Cross Training For Runners

I’ll never forget that day grinding up a brutal Bali trail—sweat pouring, legs burning—and suddenly, my lower back just gave out.

It was mile 10, and I thought I was in solid shape.

But turns out, I’d been skipping the one thing holding my whole stride together: core strength.

That day was a slap in the face.

A painful one. But it forced me to finally respect my core and what it actually does for us runners.

Hey, I’m David Dack.

I coach runners here in Bali—and if there’s one thing I’ve drilled into my own training and passed on to every runner I coach, it’s this: your core matters more than you think.

Sure, running more is the key to getting better at running. No argument there.

But ignore your core, and you’ll eventually pay for it—in sloppy form, slow times, or a trip to the physio.

Once I committed to real core work, things changed. My back pain vanished, my form tightened up, and I even shaved a few minutes off my half-marathon time.

These weren’t just minor gains—this was a shift in how my body handled mileage, especially when it mattered most: the late miles.

The truth?

Most runners skip core work. I get it.

For years, if I had 15 extra minutes, I’d run an extra two miles instead of dropping into a plank.

But now I know: those 15 minutes of core work can unlock more running gains than you’d think. That’s why I put together this guide.

Inside, you’ll find the 23 best core exercises I swear by—ones I’ve tested on myself and my athletes.

I’ll also share coaching tips, mini confessions (like how a move called the “dead bug” embarrassed me in the gym), and the no-BS reasons why this stuff works.

The 23 Best Core Exercises for Runners 

Let’s Talk Core

Want to run smoother, stronger, and with fewer injuries?

Then stop skipping your core work.

A solid core holds your posture together when the miles stack up.

Below are 25 core exercises that I’ve used in my own training—and with athletes I coach—to build a midsection that actually holds up under pressure.

These aren’t just sit-ups for show.

This is about real, runner-specific strength.

Think planks, glute bridges, twisting drills, and dynamic movements that hit every angle. I’ve laid them out from basics to tougher ones, so start where you are and build up.

1. Plank

If I could force you to only do one core move, it’d be this.

The plank hits your abs, back, shoulders, glutes—pretty much your whole trunk. It’s simple but brutal.

I used to shake after 30 seconds. Now I can go longer, but it’s still not easy—it just gets more intense the stronger you get.

How to do it:

• Start face-down, elbows under shoulders, forearms flat.
• Lift into a straight line from head to heels.
• Squeeze your glutes, tighten your abs, breathe steady.
• Hold 30–45 seconds. Work your way up.

Coaching tip:

If you sag or pike, stop and reset. Short, clean holds beat long, sloppy ones.

Want to level up? Elevate your feet or lift a leg. Trust me—this pays off when your form stays tight at mile 20.

2. Side Plank

This move checks your side-to-side strength.

It hits your obliques and hip stabilizers—crucial for trails, turns, and keeping your knees aligned.

Most runners can’t hold this long at first (I couldn’t either).

How to do it:

• Lie on one side, elbow under shoulder.
• Stack feet or stagger for balance.
• Lift your hips into a straight diagonal line.
• Hold 20–30 seconds per side.

Coaching tip:

Struggling?

Try bending your bottom knee for a shorter lever. Don’t let your chest rotate or hips wobble.

To make it harder, do dips or lift the top leg (star plank). Side planks torch your obliques in the best way.

3. Balance Plank (Arm/Leg Extensions)

Add limb movement to your plank and you’ve got a full-body challenge. This teaches your core to stay stable when your limbs are doing different things—just like in running.

How to do it:

• Start in a push-up plank.
• Lift one arm out in front, hold 2 seconds.
• Return, then lift the other arm. Repeat with legs.
• Alternate arms and legs for 30–45 seconds.

Coaching tip:

Move slowly. Don’t rush. Control is everything.

If that’s too hard, drop to all fours (bird dog).

Want a real challenge? Lift opposite arm and leg together. That’s when your core really kicks in.

4. Russian Twists

Time to add some rotation.

Russian twists hit your obliques and challenge your balance. They mimic the torso rotation that happens subtly with every stride.

How to do it:

• Sit on the ground, lean back to 45 degrees.
• Feet up (or heels down to modify), hands clasped.
• Twist side to side, tapping the ground beside your hips.

Coaching tip:

Start light—don’t go heavy out the gate. I bruised my ego once going too hard with a medicine ball.

Focus on twisting your torso, not just flailing your arms. This move helped me feel more stable on uneven trails.

5. Superman

A strong core isn’t just abs—you need a strong back, too. This move targets the muscles along your spine, plus your glutes and shoulders.

How to do it:

• Lie face-down, arms extended overhead.
• Lift opposite arm and leg, hold 2–3 seconds.
• Lower and switch. Repeat for 10–12 reps per side.

Coaching tip:

Don’t go too high—control matters more than range.

If you’re feeling it in your low back, good. That’s where you need strength to stay tall in a race instead of folding forward.

6. Single-Leg Glute Bridge

Your glutes power your stride. This move builds strength and balance one leg at a time.

How to do it:

• Lie on your back, knees bent.
• Extend one leg up, drive through the opposite heel.
• Lift hips until your body forms a straight line.
• Lower and repeat 10–12 times, then switch sides.

Coaching tip:

Start with both feet down if needed. Push from your heel, not your back.

This move helped fix my IT band pain years ago—strong glutes changed the game.

7. Windshield Wipers

These build rotational strength and challenge your control. Go slow—this isn’t a race.

How to do it:

• Lie on your back, arms out in a T.
• Lift legs to tabletop (or straight for harder).
• Rotate slowly side to side, stopping before your shoulder lifts.

Coaching tip:

Control the motion. No swinging. Your core should pull your legs back to center.

Want more?

Straighten the legs or add a med ball between your feet. Your abs will light up.

8. Scorpion Plank

A more advanced move—this one adds a knee drive twist to a decline plank. It builds strength, mobility, and serious coordination.

How to do it:

• Feet elevated on a bench, hands on the ground.
• From a plank, drive one knee toward the opposite elbow.
• Return to plank, switch sides.

Coaching tip:

Keep hips low and tight. Don’t swing the leg—move with purpose.

I love these when I need to sweat fast and build rotational control. They’ll humble you quick, but the payoff is real.

9. Boat Pose (V-Sit)

Boat pose is basically a gut-check in disguise. You’re sitting on your tailbone, legs up, chest up, trying to stay balanced while everything in your core screams.

Runners often skip it, but they’re missing out.

This move hits the front and deep core hard—think rectus abdominis and transverse abdominis—and helps you lock in posture when you’re tired late in a run. I call it the seated cousin of the plank, but meaner.

I first tried it in a yoga class and barely lasted 15 seconds. My legs were shaking like I’d just run a downhill mile at race pace.

But the more I practiced it, the more I felt my upper and lower body working as a unit. That mind-muscle link carried straight into my runs.

How to Do It:

• Sit on the ground with knees bent, feet flat.
• Shift so you’re on your sit bones, chest lifted, back straight. Think “tall spine.”
• Arms reach forward at shoulder height—or keep hands on the floor for balance if you’re new.
• Lean back a bit while lifting feet off the floor. Shins parallel is a good starting point.
• Want more heat? Straighten your legs into a full “V” shape.
• Squeeze your core to hold. Start with 10 seconds, build to 30+.

Coach’s Tips:

If you feel your lower back take over, reset. Chest up. Draw your belly button in.

And if your legs shake? Good. That means you’re working.

For a boost, try light pulses or boat pose with a twist. Runners—do this 20–30 seconds at a time, a couple rounds.

It’s one of those sneaky moves that’ll make your uphill runs smoother.

10. Dead Bug

Don’t let the name fool you—dead bugs are sneaky strong.

This move teaches your core to brace while your limbs move, which is exactly what your body does while running. It’s a top pick for runners with low back pain or who struggle to activate their lower abs.

I made the rookie mistake of rushing through it when my PT gave it to me.

Thought it was too easy… until I slowed down, pressed my back into the floor, and felt the fire light up in my belly. Humbling, but effective.

How to Do It:

• Lie on your back, arms straight up, knees bent to 90 degrees.
• Flatten your lower back into the floor.
• Slowly lower your left arm and right leg, keeping your back glued to the ground.
• Return to center, then switch sides.
• Do 8–10 reps per side, moving slow and breathing with control.

Coach’s Tips:

No arching. No rushing. If you feel your back lift, you’ve gone too far—shorten the range.

Want a challenge?

Add ankle weights or a light dumbbell. But even bodyweight hits hard when done right.

I’ve had athletes knock out their low back pain with just five minutes of dead bugs a day. Start there.

11. Bird-Dog (Kneeling Extension)

Bird-dogs are like the ground version of running: opposite limbs moving while the core holds everything together. They’re easy to underestimate but crucial for fixing wobbly running form.

I add them to almost every warm-up, especially before trail runs. They switch on your balance and coordination without taxing your joints.

How to Do It:

• On hands and knees, keep back neutral.
• Extend left arm and right leg. Pause.
• Keep hips level—no wobbling.
• Return, switch sides. 5–8 reps per side.

Coach’s Tips:

Imagine a cup of coffee on your lower back. Don’t spill it.

Brace your abs, avoid arching, and stay slow.

Add a little twist by touching elbow to knee under your body for more challenge. I’ve seen these clean up hip dips and improve posture in just a couple weeks.

12. Bicycle Crunches

These are old-school, but they still bring the heat. Way better than regular crunches, because they hit your obliques, hip flexors, and rectus abdominis—all while getting your heart rate up.

In college, our coach had us do 100 of these after track sessions. I still hear him yelling, “twist, don’t flap!”

How to Do It:

• Lie on your back, hands lightly behind your head.
• Knees at 90 degrees.
• Twist to bring right elbow toward left knee while extending right leg.
• Switch sides. That’s one rep.
• Go for 15–20 per side.

Coach’s Tips:

Don’t yank your neck. Lead with the shoulder. Extend legs low only if your back stays flat. If your form slips, rest.

I use these to fire up my core before runs and sometimes finish a session with them.

Done right, you’ll feel the burn the next day.

13. Scissor Kicks

These will light up your lower abs and hip flexors—perfect for runners who want more power in their stride. Just don’t fake your way through them. They get tough fast.

I used to hate these in track practice, but now I love them. They target the part of the core that helps drive your knees forward with each stride.

How to Do It:

• Lie on your back, hands by your sides or under your hips.
• Legs hover 6 inches off the floor.
• Raise one leg up to 45 degrees, then switch.
• Keep alternating. Aim for 15–20 per leg.

Coach’s Tips:

Back flat. Don’t let it arch. Start with small kicks if needed.

For variation, try cross-body scissors.

I use these as a finisher. The burn is real, but the payoff on hills and sprints is worth it.

14. Donkey Kicks (Glute Kickback)

These aren’t just booty builders—they’re performance boosters. Your glutes are your power plant. Weak glutes = sloppy form and injury risk. Donkey kicks get them firing without stressing your knees.

When I started doing these consistently, I felt my stride tighten up and my knees stopped aching.

How to Do It:

• On all fours, core tight.
• Keep right knee bent and kick heel toward ceiling.
• Squeeze your glute at the top.
• Lower with control. Do 12–15 per leg.

Coach’s Tips:

Don’t twist your hips.

Don’t arch your back.

Imagine stamping the ceiling. Add a band or dumbbell behind the knee if you want more load. Strong glutes = happy knees and stronger finishes.

15. Glute Bridge

Simple, effective, and underrated. Glute bridges hit the backside while opening up your tight hip flexors. Runners who sit a lot? You need this.

This was one of the first drills I did to fix my underactive glutes—and it worked.

How to Do It:

• Lie on your back, knees bent, feet flat.
• Press through your heels and lift hips.
• Squeeze your glutes at the top.
• Lower slowly. 15–20 reps.

Coach’s Tips:

Don’t over-arch. Keep knees aligned. If hamstrings cramp, bring feet closer.

For more glute work, lift your toes. Add a band or weight on hips to progress.

I hold the last rep for 10 seconds for extra burn. Total game changer for posture and hill power.

16. Mountain Climbers

These are like sprinting in plank position. Great for core, cardio, and coordination. I love throwing them in as a finisher to simulate that end-of-race grind.

How to Do It:

• Start in high plank.
• Drive one knee in, then quickly switch.
• Keep back flat, hips steady.
• Go for 20–30 seconds.

Coach’s Tips:

Form first. No butt in the air, no hips sagging.

Start slow, build speed. Quiet feet = controlled movement. Cross-body versions hit obliques harder.

Want a challenge? Try these after your long run—feel that burn.

17. Swiss Ball Roll-Out

This one builds a steel-trap core. If you’ve ever done ab wheel roll-outs, this is the friendlier version. Perfect for runners who want better form control, especially on downhills.

I started with this after face-planting on an ab wheel. It taught me how to brace hard and move slow—skills that paid off big on trails.

How to Do It:

• Kneel with forearms on a Swiss ball.
• Brace core and roll ball forward.
• Keep hips from sagging.
• Roll back to start. Repeat 10–15 times.

Coach’s Tips:

Less is more—don’t overreach.

Neck neutral, back flat. You’ll feel the shake. That’s your deep core waking up.

Do this slowly, with control. You’ll start to notice your form staying tight when you’re tired on a run. That’s the goal.

18. Cross-Body Mountain Climber (Feet on Ball)

This move is like a plank-mountain climber combo on steroids. You’ve got your feet on a Swiss ball, doing cross-body knee drives.

Sounds simple. It’s not.

Your core gets smoked trying to keep you from rolling all over the place. And when you cross that knee to the opposite elbow? Boom—your obliques are lit.

Runners, this one is gold. It trains your core to brace while your limbs move wildly. Exactly what happens when you’re sprinting up hills or maneuvering tricky trails.

I didn’t touch this move until I had mastered standard ball planks and roll-outs. First time I tried it? Rolled off the ball like a clown. Took me weeks to stop face-planting. Worth it.

How to do it:

1. Start in plank with your shins on a Swiss ball.
2. Bring your right knee toward your left elbow (under your body). Place it back.
3. Do the same with your left knee toward your right elbow.
4. Alternate sides for 5–8 reps per leg. Control matters more than speed.

Coach Tips:

• Can’t control the wobble? Start with regular ball planks.
• Tuck your pelvis and squeeze your core. It protects your back.
• Spread your feet a little for more stability.
• A softer ball sometimes helps—it molds better.

19. Medicine Ball V-Up

This one brings the heat. A V-up is already spicy—but add a medicine ball and your abs are in for a rude awakening.

Think folding your body in half while holding a weighted ball. Total-body coordination, with a deep hit to your abs and hip flexors.

I love using these as a finisher. Just like pushing through the last 400m of a race.

How to do it:

1. Lie on your back, med ball in hands overhead.
2. Lift your torso and legs at the same time. Try to touch the ball to your shins.
3. Lower slowly without letting your back arch.
4. Do 8–12 reps.

Coach Tips:

• Use a light ball (4–6 lbs). Heavier isn’t always better.
• Exhale on the way up. Engage your core like you’re bracing for a punch.
• Bend your knees a bit if your hamstrings are tight.

20. Spider-Man Plank Crunch

Channel your inner superhero. This one has you in a plank, bringing your knee to the same-side elbow. It’s sneaky tough—your obliques and hips will feel it fast.

I like this one as a warm-up too. Opens up the hips, fires up the sides. Bonus: makes you feel cool.

How to do it:

1. Get in a forearm or high plank.
2. Bring your right knee out to your right elbow. Pause.
3. Return and switch sides.
4. Alternate 10 reps per side.

Coach Tips:

• Don’t rush. Slower is harder—and better.
• Keep your hips level. Don’t twist too much.
• Think of trying to touch your elbow—even if you can’t

21. Double Mountain Climber

Take your regular mountain climber and double the chaos. You jump both feet in toward your chest, then jump them back out. Kinda like a burpee’s cousin.

It’s intense. Core, quads, shoulders—all fired up. Great for runners needing quick power bursts.

How to do it:

1. Start in high plank.
2. Jump both feet forward under your chest.
3. Jump them back to plank.
4. Do 10–12 reps.

Coach Tips:

• Land softly. Don’t let your hips sag.
• Use your core to drive the knees in.
• Break it into sets if you’re gassed.

22. Jump Squats (with Core Focus)

Sure, these torch your legs. But your core? It’s what keeps you upright and safe on the landing.

Runners benefit big here. You get power, explosiveness, and better form under fatigue.

How to do it:

1. Squat down.
2. Explode up into a jump.
3. Land softly into the next squat.
4. Do 10–15 reps.

Coach Tips:

• Keep your chest up. Core tight.
• Don’t land like a tree falling—bend those knees.
• Too intense? Start with regular squats or add a small hop.

23. Plank with Alternating Arm and Leg Raise

Plank meets bird-dog. You lift opposite arm and leg at the same time and try not to tip over.

This is a true core stability test. And a humbling one. My first time, I fell over immediately. Took practice, but now it’s one of my go-to balance drills.

How to do it:

1. Get into a push-up plank.
2. Lift left arm and right leg. Hold 2–3 seconds.
3. Lower, then switch sides.
4. Do 6–8 reps per side.

Coach Tips:

• Wider feet make it easier.
• Don’t lift too high—aim for shoulder/hip level.
• Think “reach forward and back,” not “lift up.”

Final Thoughts:

You don’t need to do all of these at once.

Pick 4–5 and rotate them into your weekly routine. Focus on form, not how many reps you can hammer out.

A few years ago, I coached a group that added 15 minutes of core twice a week.

After two months, one runner knocked five minutes off her half marathon PR. Not because she ran more—but because she ran stronger.

Consistency wins. Quality matters. Your strong core is the glue that holds your running form together—especially when you’re tired.

So… start now. Pick a few. Try them. Stick with it.

And hey—why not hit a plank right now?

Introduction: Chasing the Perfect Running Weather

Every runner dreams of that perfect running weather – the day when the air feels just right and every stride is effortless.

But what is the ideal running temperature?

As a running coach based in Bali, I’ve grappled with this question personally.

I’ve literally felt the extremes: from sweltering tropical mornings that left me drenched by sunrise, to crisp mountain air in my earlier years that made my lungs burn and my spirit soar.

Each experience taught me something profound about how temperature impacts our runs.

Let me take you on a journey through those lessons – from a terrifying heatstroke at the Solo Half Marathon to nostalgic winter training runs – combining personal stories, scientific research, and hard-earned coaching wisdom.

By the end, you’ll not only know the optimal running temperature for peak performance, but also how to thrive in any weather, hot or cold.

What’s the Best Running Temperature?

Most runners and studies agree the perfect running temperature is around 50°F (10°C) for long-distance runs Marathon performances peak in the cool 44–59°F (7–15°C) range allowing your body to dissipate heat efficiently.

Sprinters, however, prefer warmer weather near 70–73°F (21–23°C)  to keep their muscles loose and explosive.

Ultimately, the best temperature for running varies with the individual – it’s that sweet spot where you feel comfortable, strong, and fast without overheating.

Finding That Sweet Spot Between Sweat and Shivers

Let’s be honest—every runner dreams about that perfect weather run.

You know the one: where your legs feel light, the air feels clean, and every step just clicks. No dripping heat, no icy sting. Just you and the road, dialed in.

I’ve chased that feeling across some wild weather—steaming-hot Bali mornings that cooked me before sunrise… and bone-chilling winter days back when I trained somewhere a little less tropical.

And let me tell you, temperature matters.

A lot more than you might think.

So here’s what I’ve learned—from real-world screwups, close calls, and a good chunk of science-backed training—about how weather impacts your run.

Quick Hit: Best Running Temp?

According to research—and just about every seasoned runner I’ve coached—the ideal temp for long-distance running hovers around 50°F (10°C).

That’s the sweet spot where your body doesn’t overheat and can focus on moving efficiently.

In fact, elite marathoners tend to crush their times in conditions between 44–59°F (7–15°C). Your muscles stay warm, but not boiling, and your heart doesn’t have to go into overdrive just to cool you off.

Sprinters?

They love it warmer—around 70–73°F (21–23°C)—because warmer muscles mean more explosiveness. But for most of us logging miles on the road or trail, that cooler range is gold.

The Heat Slap: My Solo Half Marathon Wake-Up Call

Let’s talk about heat—and why it’ll chew you up if you don’t respect it.

I’ve had a few run-ins with it.

One time, I headed out in Bali at midday (yeah, genius move, I know). The sun was brutal—over 90°F (32°C)—and by mile three I was wobbly and lightheaded. Heart thumping like a bass drum. I had to bail and walk it in, drenched and wrecked.

But that wasn’t the worst of it.

The real gut punch came at the 2023 Solo Half Marathon.

Race morning was already hot and thick with humidity. I felt it in my bones at the starting line, but like an idiot, I thought my training would bulldoze through it.

By mile 11, the heat won.

Everything went sideways—legs locked up, vision blurred—and I blacked out. Next thing I remember, I was in a hospital bed. I’d collapsed from heatstroke. Didn’t finish. Didn’t even remember the final kilometers.

That moment taught me something brutal: toughness means listening to your body, not ignoring it.

What’s Actually Happening in the Heat?

Here’s what’s going on inside your body when it’s scorching out:

• Your body shifts blood from your muscles to your skin to help you sweat and cool down.
• That means less oxygen and fuel to your legs.
• Your heart rate spikes because it’s working double-duty.
• And your core temp climbs dangerously fast.

Running in the heat feels like you’re driving a car with the handbrake on. You’re trying to move, but everything’s fighting against you.

And yeah, the science backs it up.

A 2021 piece in Marathon Handbook confirmed that heat is the biggest factor that screws with performance and even finish rates. Every degree above that sweet spot can slow you down—and I’ve felt it in my bones.

Flip Side: Why Cold Runs Can Make You Fly

Now let’s talk cold—because when it’s done right, cool weather can feel like rocket fuel.

Some of my best runs happened on cold mornings. Not freezing, but that crisp 45°F (7°C) type of air that stings at first and then lifts you.

I remember one snowy run years ago—quiet, fresh flakes crunching underfoot—and I was gliding. No extra effort. Just flow.

Cool temps help your body regulate heat more easily. Instead of wasting energy trying to stay cool, you can focus on the run itself.

That’s why you’ll see so many PRs and records set in fall races.

Your heart rate stays steady. Breathing feels cleaner. It’s like your body has more room to perform.

Even Reddit runners talk about how they feel like they can “run forever” in the 40s. I get it. I’ve had that run-too-far-on-purpose kind of vibe on a 50°F day more times than I can count.

But Let’s Not Pretend Freezing Temps Are Easy

There’s a point where cold stops helping and starts hurting. Below freezing, things get tricky:

• Muscles take longer to warm up.
• Breathing cold, dry air can make your throat and lungs ache.
• Slippery roads mess with your form.
• And god help you if you forget gloves.

I once ran in January without gloves—rookie mistake—and my hands were so frozen I couldn’t even turn the doorknob afterward. Took 15 minutes with my armpits to thaw out enough to open the house.

That pain? Never again.

Also, don’t forget: you can still dehydrate in cold weather. You’re losing moisture through your breath and sweat—even if you don’t feel it.

What Science (and Experience) Says About the Best Running Temperature

Let’s talk weather — and not just to complain about it.

I’m talking about the sweet spot where your body runs fast, your engine runs cool, and you feel like you could go forever.

Because yes, temperature matters way more than most runners realize.

So… What’s the Magic Number?

Over the years, scientists have pored over marathon race data and lab tests to figure this out.

And guess what? The best running temps are cold — colder than most of us would consider “comfortable” for hanging out.

According to research published in Marathon Handbook, air temperature is one of the biggest factors affecting marathon finish times — and even dropout rates.

For every 1°C (1.8°F) increase above the sweet spot, times slowed down and DNFs (Did Not Finish) went up. That hurts.

The golden range?

Most studies point to 44°F to 59°F (7–15°C) as the prime zone for marathons. A long-term study on the Boston Marathon — a race that draws runners of all speeds and ages — found 46–59°F (8–15°C) to be ideal for both elites and everyday runners.

Personally, I’ve always found around 50°F (10°C) to be that Goldilocks zone — not too cold, not too warm. That’s when the engine purrs and you can hold pace without overheating.

And you’re not alone if you think 45°F feels freezing when you first step out. But trust me, once you’re moving, it’s perfect.

What About the Fastest of the Fast?

Turns out elites like it even colder. A study in PLOS ONE found that male elite marathoners peaked at around 39°F (3.8°C), while elite women ran their best at about 50°F (10°C).

Makes sense — when you’re burning fuel that fast, cooler air keeps you from overheating. I’ve seen this play out firsthand — the pros often shiver at the start line while us mid-packers are layered up like it’s winter camping.

And for the rest of us?

We’re usually best somewhere around the mid-40s°F. That lines up with how I’ve felt on race mornings — my best performances almost always came on chilly mornings when I could see my breath during warm-up.

But Wait — What About Humidity?

Temperature’s only part of the story. Humidity is the silent killer.

You’ve heard of the “real feel” or “heat index”? That’s where heat + humidity gang up on you.

Let’s say it’s 88°F (31°C). In dry conditions, sure, that’s hot — but manageable. Add 70% humidity, and suddenly it feels like over 100°F (38°C). That’s brutal.

Why?

Because sweat doesn’t evaporate well when the air’s already full of moisture, so your body can’t cool down.

Living and training in Bali, I know this struggle. I’ve run 10Ks in 80°F with 90% humidity and felt like I was drowning in my own sweat by kilometer three. It’s not just uncomfortable — it’s performance-crushing.

On the flip side, cold wind or rain can make a seemingly perfect 40°F run feel miserable. Ever been hit with icy gusts on a long run? Yeah, that’ll humble you quick.

What This Means for You

The takeaway? Cool and dry = fast. Hot and humid = sufferfest. It’s that simple — and the science backs it.

That said, we all have our own “perfect” range. Some folks run hot and prefer 40°F, others are fine at 60°F, especially for short runs. Your body size, how much you sweat, and what weather you’re used to all play a role.

But if you’re chasing that next PR? You’re praying for a start line at 50°F, overcast skies, and a dry breeze.

Warm Muscles, Fast Sprints: Why Sprinters Like It Hot

Now let’s flip the script.

All that “cool weather” stuff? That’s for endurance junkies. If you’re a sprinter, it’s a different game.

Sprinting isn’t about pacing — it’s about power. In events like the 100m or 200m, you’re done in seconds. You’re not worried about overheating; you’re focused on explosiveness. And for that, your muscles need to be warm, loose, and ready to fire.

That’s why many sprinters train or compete in warmer weather — or overdress during warm-ups to stay hot. I’ve coached short-distance runners who hated the cold. If the temp dipped below 65°F, they’d say they felt tight and slow.

There’s solid research behind it too: according to Runners Blueprint, sprinters tend to perform best around 72–73°F (22–23°C). That’s warm enough to keep muscles firing but not so hot that you’re melting.

Heck, the women’s 100m world record? Set on a warm summer day in Rome. Not a coincidence.

So while a marathoner might be praying for clouds and cool air, a sprinter is thrilled when the sun’s out.

What About Middle-Distance Runners?

Good question.

Runners doing events like the 800m or mile fall somewhere in between. They need both speed and endurance. Most prefer moderate temps — around 60°F. Not cold enough to seize up, not hot enough to slow them down.

The Real Point: Context Matters

There’s no one-size-fits-all temperature for “perfect running weather.” A sprinter’s ideal is a marathoner’s nightmare. A trail runner training in Bali has different needs than someone prepping for Boston.

But one rule still holds: if you’re going long, cooler is better. If you’re going short and fast? A little heat might be your secret weapon.

Adapting to the Heat (and Cold): What Running in Bali Taught Me About Acclimation

Let’s be real—everyone loves the idea of running in 50°F weather. It’s cool, comfortable, and your body doesn’t feel like it’s melting.

But here’s the catch: most of us don’t live in “ideal” conditions. I live in Bali. It’s hot, humid, and sticky year-round. When I first moved here, even an easy run at sunrise felt like a death march.

I’d be drenched by mile one, gasping for air, and my heart rate was through the roof—at jogging pace. One run in 78°F and 90% humidity felt worse than a 15-miler back in Europe. I actually wondered if my running days were numbered.

But here’s the thing—your body adjusts. Slowly, stubbornly, but it does.

After a couple months of steady running (and plenty of sweating), I started noticing the shift. I wasn’t overheating as fast. I could finish a 5K before sunrise without turning into a puddle.

Six months in, a 10K in the morning heat became “just another run.” I learned how to hydrate better, slow down early, and pick shady loops or routes that passed shops for a cold drink.

That’s heat acclimation in action—your body starts sweating earlier, your blood volume goes up, and everything just runs a little smoother. Studies back this up. Your system actually learns how to manage heat more efficiently. It’s wild.

I even met a local runner who thought 75°F was “cool.” Meanwhile, a guy from Florida once told me he races better in swampy heat—said 50°F felt cold to him.

It blew my mind, but it made sense. You race how you train, and your comfort zone is built by exposure.

Same goes for the cold. I’ve got a Canadian buddy who runs in freezing temps all winter. To him, 32°F is “perfect.” He layers up, protects his skin, and goes out like it’s nothing.

But when snow or ice hit, he admits things slow way down—not because of cold, but because you can’t sprint on ice without eating pavement. Fair.

What I’ve learned is this: while science tells us that ~50°F is objectively better for performance, what really matters is what you’re used to.

Acclimation isn’t about running your fastest in 90°F—because you won’t. It’s about surviving and thriving in less-than-perfect conditions.

I even throw in hot midday jogs here in Bali just to keep that heat tolerance sharp. If I ever sign up for a cool-weather race, I’ll run with the AC cranked or travel to cooler spots just to get used to it again.

Training in tough conditions builds mental strength too. If you only run when it’s “nice out,” race day surprises will wreck you.

Bottom line? You can adapt. Whether it’s heat or cold, it’s not about chasing perfect weather—it’s about learning to run smart in the weather you’ve got.

FAQs: Weather, Performance & Real-World Running

Q: What’s “too hot” to run in?

Once the heat index hits around 90°F (32°C), you’re entering danger zone. Anything above 85°F (29°C), especially with humidity, will slow you down and spike your risk of overheating. At 100°F heat index or more? I usually tell my runners to cut it short, run easy, or hit the treadmill.

If you start feeling dizzy, your heart’s racing, or you stop sweating—that’s a red flag. Walk it in, cool down, and live to run another day.

Q: What temp is “too cold”?

Cold’s not the enemy—it’s frostbite and slipping on ice. Most runners can go down to 0°F (-18°C) with layers and protection.

But when the windchill drops below -20°F (-29°C), you’re risking skin damage fast. If it’s icy or your lungs hurt from the air, it’s time to reconsider. Treadmills exist for a reason, and using one doesn’t make you soft—it means you’re smart.

Q: Is cold better than heat for racing?

Yep. According to multiple studies (like from youraustinmarathon.com and runnersblueprint.com), marathon times drop as temps rise. Most people run best between 40°F and 60°F (4–15°C).

Why?

Your body doesn’t waste energy cooling down, so your pace holds longer. You might be a minute slower per mile at 85°F than at 55°F. Even a 10°F shift can affect performance by a few percent. Cold’s better—until it’s too cold and your legs freeze up.

Q: Do I burn more calories running in the cold?

A little.

Your body does work harder to stay warm, especially if you’re underdressed and shivering. But don’t expect a major fat-loss boost just from cold air.

In fact, running in heat feels harder but doesn’t burn more—it just feels like it does because of water loss. Want to burn calories? Focus on effort, distance, and consistency, not the weather.

Q: What should I wear when it’s ~50°F out?

Ah, the sweet spot. In 50°F (10°C), I usually go with shorts and a long-sleeve or just a tech tee with sleeves I can push up. Maybe gloves for the first few miles, a buff if it’s breezy. You don’t need a jacket unless it’s windy.

Trick is to feel a bit cool at the start—by mile 2, you’ll be golden. I ran a race once at 52°F in shorts and a short-sleeve with gloves. I froze for five minutes, then felt perfect the rest of the way.

When I first started running, I never thought much about the ground beneath my feet.

I just grabbed my shoes and hit the pavement.

But over time, I learned that where you run matters just as much as how far or how fast.

Running on the wrong surface can slow you down, wear you out, or worse—cause injuries that keep you sidelined.

Whether you’re just starting out or training for your next race, picking the right surface can make a huge difference.

In this guide, I’ll walk you through the pros and cons of different running surfaces and share tips to help you run smarter, feel better, and stay injury-free.

Sounds like a great idea?

Let’s get to it.

Pavement (Concrete & Asphalt)

Pavement? Yeah, it’s tough on your body, we all know that. It’s reliable, but it feels like running on a concrete block that’s not doing your knees any favors.

Pros:

• Convenience: Pavement’s everywhere. You can always find a route through the city, and no worrying about running out of track. It’s quick, easy, and ready when you are.
• Asphalt’s softer: Asphalt’s got a little give to it, so it’s easier on your joints than concrete. Concrete? Not so much.

Cons:

• Joints: Yeah, poor knees! You’ll feel it after a while.
• Shins, calves, and ankles: Pavement’s tough on your legs. You’ll feel it in all the wrong places.
• Potholes: Watch out for those potholes—they’re everywhere, and they’ll throw off your stride.

My best advice?

Watch out for cambered roads. Try running on them one way for a week, then switch it up. It’ll help balance your muscles and keep that knee strain in check. Pavement isn’t friendly, but sometimes, you gotta deal with it. Mix it up and be smart about it.

Grass & Dirt Trails

Grass and dirt trails are ideal in my opinion. The soft ground means less pounding, and it gets those stabilizing muscles working harder.

Feels good, right?

Pros:

• Easy on your joints: If your knees are feeling the pavement, grass and dirt trails are like a vacation for your legs.
• Feels like a break: Running through a well-maintained park or field feels like you’re floating. Seriously, it’s like a spa day for your legs.

Cons:

• Uneven terrain: Can be tricky. If your ankles aren’t stable or you’re not careful, you might twist something.
• Wet grass: Forget it. Unless you’re into slipping around like it’s an ice rink, stay away from wet grass.

My best tip?

If you’re new to trail running, focus on stabilizing those ankles and getting your form solid. When it’s wet, stick to dirt if you can. It’ll save you a lot of hassle and make the run way smoother.

Sand

Running on sand? It’s a killer for your legs and core, but in a good way. It absorbs the shock, so it’s a little easier on your knees than pavement. But be careful—the ground’s uneven, so one wrong step, and you could twist an ankle.

Pros:

• Strength training: Running on sand is like a workout for your legs and core. You’ll feel it in your calves, quads, and abs with every step. It’s awesome for building strength.
• Gentler on your joints: Sand absorbs the impact, making it easier on your knees compared to pavement.
• Push yourself: If you’ve got the energy, running on sand feels like you’re conquering a challenge.

Cons:

• It’s tough: Running in deep sand is way harder than you think. Your legs will feel heavy and tire you out faster than you expect.
• Uneven ground: The ground’s soft, so stay focused. A wrong step and your ankle will remind you it’s there.
• Slower pace: Sand’s a bit slower, so don’t expect to set any speed records. It’ll feel like you’re running through mud.

My best advice?

Run near the waterline where the sand’s firmer. It’ll make a huge difference in how fast you can go without burning out too quickly. Use the soft sand for a challenge, but keep it smart for when you’re really ready to push yourself.

Treadmill

Let’s be real—the treadmill isn’t fun, but it’s got its place. It’s perfect for when the weather’s bad, but yeah, it can get pretty boring. You control everything—speed, incline, no worrying about traffic.

Pros:

• Predictable: You control the speed, incline, and there’s no potholes or traffic to deal with. Simple.
• Injury recovery: If you’re coming back from an injury, the treadmill is soft and safe while you get back into it.
• Work on your form: Plus, it’s easier to focus on your form without worrying about bumps or hills.

Cons:

• Boring: Staring at the same spot for miles isn’t the most exciting thing.
• No scenery: You’re not seeing much. The lack of change in environment messes with your head a bit.
• No real-world adjustments: No hills, no wind, no turns—it can throw off your natural stride and form.

My best advice?

Throw a 1% incline on that treadmill. Trust me, it’ll mimic outdoor running better and keep your workout from feeling like you’re walking on a conveyor belt to nowhere. You’ll feel more like you’re actually out there running. Here’s how to get started on the treadmill.

Trails (Woodland, Mountain, etc.)

Want to feel like a pro? Hit the trails. They’re awesome for strength and adventure, but yeah, you gotta be careful. Trails are amazing, but they can be rough on your ankles if you’re not paying attention.

Pros:

• Adventure time: Trails take you to cool spots, and the bumpy ground is great for building strength.
• Easier on your body: Trails are easier on your joints than pavement, and the less impact is a win in the long run.
• The real deal: The fresh air, the quiet—this is the kind of run that’ll leave you feeling alive.

Cons:

• Roots, rocks, and mud: One wrong step, and you’re twisting an ankle. It’s beautiful, but don’t expect a fast pace if you’re dodging rocks and roots all the time.
• Focus on footing: You’ll need to pay more attention to where you step than how fast you’re running.

My best advice?

Keep an eye on the ground. Most hazards can be avoided if you just watch your step. Start slow on the easy trails before jumping into the gnarly stuff. That way, you’ll build confidence and strength while keeping those ankles in check.

Track

Track time—this is where you go to push your speed! The track’s flat and smooth, perfect for crushing lap times—just don’t let it get boring.

Pros:

• Speed work: If you love speed work, the track’s your best friend. The surface is smooth, no bumps, and you can easily track your distance.
• Body-friendly: The synthetic surface is easier on your body than concrete, so you can really push yourself without worrying about wrecking your joints.

Cons:

• Boring: Lap after lap, it can get old.
• Tight turns: Those tight turns can mess with your knees and hips, especially if you’re always running in the same direction.
• Monotonous: Don’t make the track your go-to every day, or it can get repetitive.

My best advice?

Mix it up and change directions every few laps (but make sure to abide by local etiquette). Your body will thank you, and it’ll make your workout way more interesting.

Listen to your body, and switch things up to keep your muscles guessing and prevent overuse injuries.

Your body’s tougher than you think, but it needs the right kind of variety. B

e adaptable, creative, and always keep your runs interesting! Keep building that foundation and enjoy the ride.

FAQ Section (Optimized for Featured Snippets)

What is a Cambered Road?

A cambered road is slightly tilted to one side to help with water drainage.
The downside? One leg works harder than the other, throwing off your stride and putting extra stress on your joints.

How Does a Cambered Road Affect My Running?

Running on a cambered road messes with your alignment, making your body fight against gravity. It’s like running uphill on one side and downhill on the other—not exactly easy on your body.

What’s the Difference Between Asphalt and Concrete for Running?

Asphalt is softer and has a bit of give, making it easier on your joints. Concrete, on the other hand, is much harder, which can lead to more wear and tear on your body over time. If you have to choose, asphalt is the better option for long runs.

How Does Trail Running Affect My Body Compared to Pavement?

Trail running offers a softer surface, so it’s easier on your joints. But the uneven ground forces your muscles to work harder to stabilize your body. It’s a great way to build strength, but also be careful of rocks, roots, and other obstacles that could cause injury.

What’s the Best Surface for a Long Run?

If you’re aiming for a long run, asphalt or well-maintained dirt trails are your best bets. They’re softer on your body than concrete, but still provide enough stability to keep you moving without too much strain. Avoid running on rough trails or concrete for long distances unless you’re really trying to push your limits.

Why Does Running on Grass Feel Easier on My Body?

Grass provides a natural cushion that absorbs a lot of the shock, making it easier on your joints compared to harder surfaces like pavement. However, it can be a little tricky to run on because of uneven ground, so make sure you’re watching your step. Running on grass can feel like a break for your body but still gives you a solid workout.

Can Running on Sand Help Build Strength?

Yes! Running on sand is like a strength workout for your calves, quads, and core. It’s tough, but it’s great for building muscle.
The only downside is it’s much harder to maintain speed, so if you’re looking to race, stick to more solid surfaces. But for strength and endurance, sand’s a killer option

A lot of runners worry about how running impacts their knees and joints. I’ve been there myself—put in tons of miles and felt those joint aches.

But honestly? Running has been one of the best things I’ve done for my body in the long run.

And hey, science has my back on this one too.

Let’s talk about how running affects your joints, what can go wrong, and how to keep them happy in the long run.

Spoiler alert: it’s not running that messes up your joints, it’s how you run and how you take care of your body between runs.

Let me get to it.

Running: The Good, The Bad, and The Myths

First off—running’s not automatically bad for your joints.

You won’t automatically end up with arthritis just from running. Studies show runners often have healthier knees than people who sit around all day.

But don’t get too excited just yet—let’s talk about where things can go wrong. Running’s great, but you’ve got to be smart about it to keep your body in check.

Myth #1: “Running Causes Arthritis”

The myth that running causes arthritis? It’s outdated and debunked. In fact, a study showed that sedentary people have nearly three times the risk of developing osteoarthritis compared to recreational runners.

But here’s the kicker: It’s all about how you run. And yep, form is everything.

The Real Risk: Overuse and Poor Form

Look, if you’re running every day without paying attention to your form and recovery, you’re asking for trouble.

Overuse injuries like patellar tendonitis or IT band issues? They’re no joke, trust me. And if you’re new to running, doing too much too soon will make your joints throw a tantrum.

Staying injury-free? It’s all about consistency and being smart with your effort.

So, What Actually Happens to Your Joints When You Run?

Believe it or not, running actually helps strengthen your knees. Studies show that regular running can help ‘condition’ your knee cartilage. Basically, it makes your knee cartilage stronger over time.

So, not only can your knees handle the stress, they actually adapt and get stronger.

But don’t overdo it—take it slow and steady. Too much of anything is still too much. If you’re running like you’re preparing for an ultra every day and skipping recovery, you’re setting yourself up for trouble.

Long-distance or high-volume training without proper rest? That increases your risk of joint issues big time.

The Power of Strengthening

Weak muscles? Yeah, they can cause joint issues. Think of your muscles like bodyguards for your knees. If your muscles aren’t strong enough, guess who gets the hit? Your knees.

That’s where cross-training comes in—things like strength training, biking, or swimming. Building up your quads, hamstrings, and calves gives your knees the backup they need.

Form Matters More Than You Think

Bad form? It’s like a fast track to injuries. If you’re landing on your heels or your foot is too far ahead of you, you’re asking for trouble. Focus on landing mid-foot and keeping your posture tall.

Small tweaks like this can save you from a lot of pain later on. Not sure about your form? Get someone to check it out. It’ll be worth it, and it could make a big difference in keeping you injury-free. You can also check my guide here.

What Can You Do to Protect Your Joints?

Here are few of my best tips to help protect your joints while performing high impact exercises.

Choose the Right Surface

I get it—concrete’s easy, and it’s everywhere. But it’s tough on your joints. So, why not mix it up?

Try switching it up with softer surfaces, like grass or dirt trails. It won’t get rid of the impact entirely, but it’ll definitely take the edge off.

I made the switch years ago, and my knees are much happier now.

Proper Footwear is Non-Negotiable

Look, I’ve been there—running in shoes that were on their last leg because they “still felt okay.” Don’t make that mistake.

Your shoes are your first line of defense for your knees. If your shoes are worn out, your knees will feel it.

Get fitted for shoes that match your foot type and running style. Don’t just grab any pair off the shelf. It’s worth the time and effort to find what works for you.

Build Those Muscles

Want to keep your knees in top shape? Add strength training to your routine.

Lunges, squats, and leg extensions—they’re your friends. These exercises help build the muscle stability your knees need so you’re not relying solely on the joint for support.

A bit of strength work goes a long way to keeping your knees strong and injury-free.

Don’t Forget to Rest

Rest is your secret weapon for recovery. I get it—rest might seem like slacking off, but trust me, your body needs it. It’s when your muscles and joints repair and get stronger.

After a tough run or training week, don’t skip the rest. Overtraining is the quickest way to turn healthy knees into sore ones. Your body will thank you for giving it the rest it needs.

Conclusion: The Takeaway

Running doesn’t have to hurt your knees—as long as you’re doing it the right way. Pay attention to your form, make time for recovery, and don’t skip your strength training. Your knees will thank you, and you’ll be running strong for years!

Quick Tips for Healthy Knees:

• Run with proper form to protect your knees
• Choose softer surfaces like grass or dirt to reduce impact
• Strengthen muscles around the knees for better support
• Get fitted for the right running shoes to protect your joints
• Allow for proper recovery between runs to prevent injury

FAQ

Can running cause knee arthritis? No, running itself doesn’t cause arthritis. In fact, studies show runners often have healthier knees than sedentary people. The key is to run with proper form and allow for recovery.

What’s the best surface for avoiding joint injuries? Softer surfaces like grass or dirt trails are easier on your joints compared to hard concrete or asphalt. Mix it up and avoid always running on hard surfaces.

How can I strengthen my knees for running? Strength training exercises like lunges, squats, and leg extensions help build muscle around your knees, providing better support and reducing the risk of injury.

Many marathon training plans have you running five or six days a week. That can sound overwhelming.

You might have a busy life or worry that running too much could get you hurt.

This might make you wonder: Can I train for a marathon by running only three days per week?

As a running coach, I’ll be honest – I’m a bit skeptical of such a low-mileage approach.

I usually recommend training about five days a week with plenty of easy running. (We call those easy efforts Zone 2 training, which means running at a comfortable pace.)

However, I also understand that not everyone has the time or ability to run that often. Some runners have tight schedules or past injuries.

For those runners, three runs a week might be all they can manage.

Still want my answer? 

Then I gotta say yes – you can finish a marathon with only 3 runs per week (the keyword here is finishing a marathon, not running a fast one).

But you have to be smart about it.

Each run becomes very important when you only have three.

You’ll also likely need to do some other exercise on the non-running days to build your endurance.

Let’s talk about how such a plan works and how to make the most of it.

How to Train for a Marathon on 3 Runs per Week

I’ll level with you.

When runners ask me for a 3-day-a-week marathon plan, I often start by handing them a 5-day beginner plan!

Then I tell them to drop a couple of the weekday runs and replace it with cross-training (like cycling or swimming).

This way, they’re still staying active five days a week.

But only three of those days involve running.

That leaves us with three key runs in the week. These three runs are the essentials that every good marathon training plan needs.

If you nail these three, race day won’t feel like a struggle.

Instead, you’ll feel in a good spot despite not fully committing to training. 

Let me break down the plan even further.

The Three Important Runs:

• The Long Run: the distance-building run for endurance.
• A Faster Run (Tempo or Intervals): a run to work on speed and strength.
• An Easy Run: a short, relaxed run to aid recovery and add some mileage.

Long Runs – Building Endurance

The long run is the most important workout of your week.

This is where you practice running far, gradually building your distance over time.

If you’re on the slower side, I might cap your long run based on time instead of distance.

For example, you might stop after 3 to 3.5 hours, even if you haven’t hit 18-20 miles. This keeps you from burning out and gives your body a better chance to recover.

When you do your long run, the goal is to run at an easy, conversational pace. 

You should be able to talk in full sentences without gasping for air. This pace is called your aerobic zone (or Zone 2). I’d also recommend you take some breaks during these extended efforts.

It’s a level where you’re working but still comfortable, and it’s key for building endurance without pushing too hard or risking overuse injury.

Pacing for the Long Run

The goal? Take it slow—find a pace that builds your endurance, not one that leaves you gasping for air halfway through.

• Beginners: Aim for about 90 seconds slower per mile than your marathon pace. The focus here is on being out there for the time, not worrying about speed.
• Intermediate Runners: You’re looking at 60-75 seconds slower. You’ve got the distance down, now it’s about building that stamina.
• Advanced Runners: You may only need to slow down by 60 seconds per mile. Your goal is endurance, not speed.

Tempo Run

A tempo run is all about running at a “comfortably hard” pace for an extended period.

You’re not sprinting, but you’re not cruising either.

A typical tempo run lasts 20-40 minutes at this steady, hard pace. That doesn’t include your warm-up and cool-down, by the way.

Tempo runs train your body to maintain a faster pace for longer, which helps improve your overall speed.

Here’s a good example: jog easy for 10 minutes to warm up, then run 20 minutes at a strong, steady pace, then cool down with a 10-minute jog.

Interval Workout

Intervals are all about short bursts of fast running with quick recovery periods in between.

For example, you might run hard for 2 minutes, then jog or walk for 2 minutes to catch your breath.

You repeat that cycle several times.

Interval workouts (sometimes called “repeats” when done on a track) are great for building speed and power.

They’re tough, but they can also be a lot of fun. You get to push yourself hard, then take a break and do it again.

Here’s an example: 6 × 400-meter repeats at a 5K pace, with a 2-minute rest between each.

These intervals help train your legs to run fast and teach your body to recover quickly, which is key for improving speed.

In a 3-day training plan, you might do intervals one week and a tempo run the next. It really depends on what your plan calls for.

Both interval workouts and tempo runs will help make your marathon pace feel easier over time.

The Key to Success: Cross-Training

I know what you’re thinking: “Doesn’t cross-training just add more work to my already busy schedule?”

Let me explain why it’s worth it.

Cross-training can help build strength and endurance while keeping you injury-free. And it’s all about doing other forms of exercise besides running.

This can include many activities, such as:

• Cycling (riding a bike)
• Swimming
• Brisk walking or hiking
• Using an elliptical machine (a low-impact exercise machine that simulates running)
• Rowing or cross-country skiing
• Strength training

Here are some great ways to cross-train:

• Cycling: Hop on your bike for 45 minutes and keep your cardio strong, without the pounding that running puts on your joints.
• Swimming: Swimming gives you a killer full-body workout, boosting your cardio while giving your legs a break.
• Elliptical: Got access to an elliptical? It’s a great way to mimic the running motion without the impact.

These activities keep your fitness up while giving your legs a break.

Let’s say your 3-day running schedule looks like this:

• Monday: Long run (10-15 miles)
• Wednesday: Tempo run (5-7 miles)
• Friday: Speed work (intervals or hill sprints)

For the days in between, cross-train to work your heart and keep your muscles strong:

• Tuesday: Swim for 30-45 minutes, focusing on endurance with a steady pace.
• Thursday: Do a 45-minute cycling session at a moderate intensity to keep your legs active without overloading them.
• Saturday: Take it easy with the elliptical for 45 minutes, focusing on maintaining a good rhythm and heart rate.

Cross-training isn’t just for fitness—it helps keep you injury-free and gives you the break your legs need.

Rest

Of course, rest is important too.

Make sure to take at least one full day off each week to let your body fully recover. On a 3-run schedule, you might run on Monday, Wednesday, and Saturday. Then you could do cross-training on two or three of the other days. That leaves at least one or two true rest days.

Find a routine that fits your life. With a 5-day training week, you get two days of full rest. This should be more than enough.

Strength Training for Runners

I’m a big fan of strength training.

It helps build your muscles, improve bone density – I can go on and on.
And you don’t need a lot of it, to be honest.

Just 20-30 minutes twice a week is all it takes to keep your body strong and ready for race day.

Key exercises every runner should include:

• Squats: Target your quads, hamstrings, and glutes.

Thank you for dropping by.

Keep training strong.

If you’re like me, you’ve probably kept running shoes and gear way past their prime.

But here’s the truth: holding onto old gear can actually hurt your performance—and lead to injury.

Let’s chat about how long your gear should last before it’s time to say goodbye. I’ll help you figure out when it’s time to let go and keep your runs as strong as possible.

How Often Should You Replace Your Running Shoes?

Your shoes? They’re the foundation of every great run. But even the best shoes wear out eventually.

You’ve probably heard the rule: change your shoes every 300-500 miles. That’s a good starting point, but there’s more to it than just miles.

I’ve done it too—kept running in shoes even when they were done, just to save a few bucks. Trust me, that’s when injuries pop up out of nowhere.

So, how do you know when to finally let them go?

1. The Surface You Run On

Where you run makes a big difference too.

Running on pavement? Your shoes won’t last as long.

Trails are kinder to your shoes.

But if you take road shoes onto rocky trails, they’ll wear out faster.

2. Your Running Style

Are you a heel striker or do you land on your forefoot? The way you land affects how your shoes wear down.

If you’ve got a heavy heel strike, you’re burning through that cushioning much faster.

Next time you’re at the store, check out the wear pattern on your shoes—it’ll give you a good idea of your running form.

Best tip? If you run a lot, get two pairs of shoes and switch between them. This way, each pair gets a rest, and they’ll last longer.

Signs Your Running Gear Needs Replacing

• Thin spots
• Visible holes
• Loss of elasticity around toes/cuffs

Don’t wait until it hurts—replace those shoes before they mess up your form and cause injuries.

How Often Should You Replace Your Running Sports Bras for Comfort and Support?

Sports bras are meant to give you support, and once they start losing that, it’s time to replace them. If the elastic bands start to stretch out or the straps lose their shape, it’s a clear sign they’re done.

On average, you should replace your sports bras every 6-12 months, depending on how often you use them.

How Often Should You Replace Your Running Tops and Bottoms?

Moisture-wicking fabrics are a game changer—when they’re fresh. But once they lose their elasticity or start thinning out, they’re not doing their job anymore.

If you notice stubborn smells that won’t come out or the fabric starts feeling “sticky,” it’s time to let go.

I used to hold onto my favorite running shorts way too long, even though they were getting a little too see-through. Finally, I had to retire them after a very awkward moment during a group run. Trust me, you don’t want to wait that long.

When to Replace Your Running Hat

I’ll be honest: I used to hang on to my hats way longer than I should have. That favorite cap of mine? It had seen better days—faded color, sweat stains, and the brim was drooping like it had been through a hurricane.

But we runners get sentimental about our gear, right?

Here’s the deal with hats: they’re meant to shield you from the sun and keep the sweat out of your eyes. But once the shape starts to go, or the fabric becomes too worn out, it’s time to replace them.

And, let’s be real, if you notice that sweatband starting to stretch out or smell funky no matter how many times you wash it, that’s your signal to let it go.

When to Replace Your Running Sunglasses

Those sunnies are supposed to protect your eyes from the sun, but if they’ve seen too many miles, they might be doing more harm than good.

If your sunglasses’ lenses are scratched, you’re not just dealing with a cosmetic issue—you’re compromising your vision.

A good pair of running sunglasses should give you clear, distortion-free vision to see your path ahead. Once they start to get foggy, or the frames are too loose, you might as well be running blind.

My advice? If they’re slipping down your nose during your runs, it’s definitely time for an upgrade. Don’t wait for them to fall off mid-stride.

When to Replace Your Running Gloves

Gloves aren’t just for keeping your hands warm during those chilly runs—they’re a crucial part of your running kit when it comes to comfort.

But here’s the thing: running gloves have a shelf life. They’re taking on sweat, dirt, and the elements all winter long, so over time, they start to lose their insulation or get holes where you don’t want them.

Once they’ve been through a few seasons, and you notice that the fabric isn’t as warm or snug as it used to be, it’s time for a new pair.

Don’t wait for your gloves to develop holes and leave your hands exposed to the cold. Trust me, it’s not fun running with frozen fingers.

When to Replace Your Running Watch or GPS Device

We all rely on that trusty GPS watch to track our runs, monitor our heart rate, and help us stay on pace. But like everything, even your tech needs replacing every now and then.

Battery Life:

If your GPS watch is struggling to hold a charge, or it takes forever to charge up, that’s a red flag. A battery that dies quickly is a sign the watch is on its last legs. Don’t wait for it to give out in the middle of a run.

Accuracy:

Running is all about tracking progress, and if your watch starts giving you inaccurate readings—whether it’s distance, heart rate, or pace—you’re better off investing in a new device.

A GPS watch is meant to be your training partner, and if it’s no longer reliable, you’re just running blind.

When to Replace Your Running Socks

Running socks are one of those things you don’t think about until it’s too late. You’re out on your run, and suddenly, there’s a blister forming. Well, guess what? Those socks you’ve been holding on to probably have something to do with it.

Signs They Need Replacing:

• Thin spots
• Visible holes
• Loss of elasticity around toes/cuffs

When to Replace:

If you’re running consistently, replace them at least every 6 months. It’s a small investment that’ll save you from discomfort, and possibly injury.

How to Store Your Running Gear

Proper storage can seriously extend the life of your gear. You might think tossing everything into the laundry basket or leaving your shoes by the door is fine, but trust me, how you store your gear makes a big difference.

Shoes:

Don’t leave them in a damp, humid environment—like the garage or the trunk of your car. The moisture can cause the material to break down faster. Instead, let them air out after a run and store them in a cool, dry place.

Clothing:

Running clothes, especially moisture-wicking fabrics, need to be stored in a way that keeps them from losing their elasticity. Avoid tossing them in a laundry hamper where they might get moldy. Hang them to dry if possible, and store them in a cool, dry area to preserve the fabric.

Proper storage means your gear stays in better shape for longer, saving you money and preventing unnecessary wear and tear.

Frequently Asked Questions About Running Gear Lifespan

1. How do I know if my running shoes are still providing the right support?

As your shoes wear down, the cushioning and support degrade. To check if your shoes are still offering the support you need, press the midsole (the cushy part) with your thumb. If it feels stiff or hard, it’s time to replace them. Also, if you notice pain in your knees, hips, or back after a run, your shoes may not be supporting you correctly anymore.

2. Can I extend the lifespan of my running shoes?

Yes! Rotating between two pairs of shoes can help extend their lifespan. By alternating between them, each pair gets a break, allowing the cushioning to recover. Also, always let your shoes dry out fully after each run and store them in a cool, dry place to avoid moisture breaking them down faster.

3. How can I tell if my running gear is too tight or too loose?

If your gear starts to feel tight or restrict your movement during a run, it’s time for a new piece of equipment. Tight clothing can lead to chafing and discomfort, while loose clothing can get in the way of your performance. Pay attention to any signs of discomfort, like rubbing or shifting, during your runs.

4. How often should I replace my running socks if I have blisters?

If you’re getting blisters regularly, even though you’ve tried new shoes or different socks, it could be time to replace your socks. Over time, running socks lose their elasticity and cushioning, which may no longer provide the protection your feet need. You should aim to replace them every 6 months or sooner, depending on how much you run.

5. How long do running sunglasses typically last?

Running sunglasses can last anywhere from one to three years, depending on how often you use them and how well you care for them. If the lenses get scratched, it’s time to replace them to ensure proper protection for your eyes.
