We’ve all heard the classic “10% rule”
Don’t bump your weekly mileage more than 10% from one week to the next. That’s decent advice for beginners. But it’s not some sacred rule.
One study showed that about 20% of runners got injured, whether they increased by 10% or 50%. So the real goal isn’t sticking to a number—it’s giving your body enough time to adapt.
Here’s a smarter take, from legendary coach Jack Daniels: add the same number of miles as the number of days you’re running. Run five days? Add 5 km next week. Cap your jump at 10 km max, and then sit there for a few weeks to let your body catch up.
Think of it like stair-stepping:
- Go up (increase mileage)
- Walk a few steps (hold mileage steady)
- Then go up again
Another approach I love is the “3 up / 1 down” cycle. Here’s what that might look like:
- Week 1: +5–10% mileage
- Week 2: Add a little more
- Week 3: Push slightly again
- Week 4: Ease back 20–30%
Cutback weeks are a godsend. They don’t make you lose fitness—they actually build it by giving your body space to adapt.
And if you’re coming back from a break? Don’t panic. Daniels says experienced runners can bounce back faster. I’ve gone from 0 to 60 km/week in 3–4 weeks after a break, but only because I had that base built already. If you’re just starting out, take it slower. Much slower.
Bottom line: don’t do surprise mileage jumps. Stick to a plan, listen to your body, and hold new levels before climbing again. Small increases now mean big gains later.
Build a Base Before You Chase Speed
No one builds a house on sand. You shouldn’t build workouts on a weak base either.
Before you ever lace up for a tempo session or hill sprints, you need to get time on your feet. That means easy, steady runs—mostly in Zone 2. The kind where you can talk without gasping.
According to TrainingPeaks, this kind of base work boosts your fat-burning ability, lactate clearance, and general stamina.
Here’s what solid base training looks like:
- Run slow. Most runs should be “easy.” You should be able to chat. That’s where the magic happens—slow miles build your endurance engine.
- Track minutes, not just distance. Don’t obsess over pace or kilometers. Just aim for total time spent running. 30 minutes is 30 minutes, whether it’s 4 km or 5.5 km. That time adds up.
- Add gradually. If you’re at 30 km/week and feeling good, maybe go to 35 the next week. Then hold. Don’t just chase numbers.
- Start small. New runners? Aim for 3–4 runs per week, 20–30 minutes each. That’s plenty.
I’ve coached folks who tried to go “fasted and furious” in week one—and ended up sidelined. I’ve done it myself. One time, I charged into a fast finish run on tired legs and blew up. It took me a week to recover.
Lesson learned: speed is earned. Patience pays off.
Eventually, your easy runs start to feel faster, even though you’re putting in the same effort. That’s the beauty of aerobic development. Your engine gets stronger, and suddenly, that 6:30/km pace feels like jogging through a breeze.
Make the Long Run Your Weekly Anchor
If marathon training has a backbone, it’s your weekly long run. This workout is where your body learns to handle real mileage stress. Not just survive it—absorb it and adapt.
It’s where your legs get tired, your brain starts bargaining, and the magic happens anyway.
A good ballpark? Make your long run around 20–30% of your total weekly mileage, give or take. So, if you’re running 60K a week, your long run might be somewhere in the 12–18K range.
Some runners stretch that over time—starting with a 14K and building all the way to 30–35K over months. That range works well for most runners, and I’ve seen it play out hundreds of times in the real world.
Here’s how to get your long run right:
- Build it smart: Add about 1–2K per week, then back off every 3–4 weeks with a shorter “cutback” run. A steady example: 14 → 16 → 18 → 15 (cutback) → 20 → 22 … You’re not trying to break yourself—you’re teaching your body to go long without crashing.
- Pace for time, not ego: Keep it comfortable. If you’re gasping early, back off. This isn’t a tempo run; it’s a lesson in stamina. I’ve even used run-walk intervals (like 5 min run/1 min walk) during brutally hot days. No shame—just smart training.
- Fuel like it matters—because it does: I once passed out on a curb at 25K because I thought I was too tough for mid-run calories. I wasn’t. Now, I always eat something before a long run (usually a banana), and take a gel every 40–50 minutes. Practice fueling and hydration during your long runs so race day isn’t a stomach disaster.
- Recover like it’s part of training: After a long one, you’re in mini-race recovery mode. Stretch, sleep more, and maybe trade your next-day run for a walk or spin session. You earn your fitness during the run—but you build it during recovery.
Long runs teach you that you’re capable of more than you think.
The first time I ran 30K, I finished wrecked—but proud. I ate two plates of nasi campur and slept like I’d crossed a finish line (even though it was just training).
These runs are proof. You’re doing the work. So next time you’re dreading it, remember: it’s just 20–30% of your total week. You’ve got the rest of the week to go easy and recover.
What’s your longest run so far? What distance are you building toward?
Recovery Isn’t Optional—It’s a Weapon
Let me tell you straight: if you train hard and never pull back, your body will force you to. I learned that the hard way with shin splints that sidelined me for weeks because I thought rest was for weaklings.
Here’s the real game: recovery weeks make you stronger.
Every 3–4 weeks, cut your mileage by about 20–35%. These “cutback” weeks are where your body rebuilds. For newer runners, that might also mean throwing in a rest day or swapping a run for a swim or bike ride. I call these reset weeks, and I swear by them.
Red flags you’re pushing too hard:
- Resting heart rate climbs: If your morning HR is 5–10 bpm higher than usual for a few days, ease off.
- Runs feel like slogs: If every mile feels like concrete, and even your easy runs feel hard, it’s time to back off.
- Mood & sleep go sideways: Snapping at people? Tossing all night? Don’t ignore it—your body’s waving the red flag.
- Nagging aches that linger: That tiny shin or hip pain that won’t go away? That’s not “toughness” talking—it’s an injury loading up.
If any of these show up, drop the ego and rest. Missing a few days is nothing. Getting benched for two months? That’s the real problem.
As Runspirited puts it, “You don’t lose fitness for two weeks of inactivity”. In fact, I’ve had recovery weeks that left me bouncing back with stronger legs and fresher lungs.
How to recover like a runner, not a slacker:
- Deload on purpose: Every few weeks, drop the mileage and back off the pace. If you ran 50K one week, hit around 35–40K the next.
- Cross-train smart: Trade pounding pavement for low-impact movement—swimming, biking, yoga. Studies show this can help preserve your cardio fitness and aid in injury recovery.
- Dial in sleep, food, and mobility: 8 hours of sleep isn’t luxury—it’s training. Stretch, foam roll, do band work. These habits keep the wheels turning.
I used to think cutting mileage meant I was slacking. Now I know better. Recovery isn’t weakness—it’s strategy. It’s what lets you train hard again next week.
Have you scheduled your next cutback week? What’s your recovery plan look like?
Strength Work = Mileage Insurance
Want to run more without falling apart? Lift some stuff.
You don’t need to become a bodybuilder. Just a couple of 30-minute sessions a week with bodyweight or bands can change the game. The goal? Build a body that can take a beating and bounce back.
Research backs this up: A meta-analysis showed that every 10% bump in strength work can reduce injury risk by 4%. That’s not just gym talk—that’s science.
Here’s what I focus on:
- Glute bridges & hip thrusts: These power up your hips and glutes—key for keeping your form solid late in runs.
- Lunges & single-leg squats: Great for leg strength and balance. These make a huge difference on hills and uneven trails.
- Core work: Planks, side planks, and anti-rotation moves hold your stride together when you’re tired.
- Calf raises: Tiny move, big impact. Strong calves help absorb shock and prevent lower-leg injuries.
I usually tack strength work onto easy run days. That way, I’m not overloading recovery days, and the body learns to move tired. It’s armor-building. I swear by it.
Over time, I noticed a difference—less soreness, faster recovery, and fewer days off from aches. When you’re stacking big mileage, these sessions keep you from falling apart.

Switch Up the Surface & Cross-Train to Stay in the Game
If you’re banging out 80 kilometers a week on the same stretch of pavement, don’t be surprised if your body starts talking back. I’ve been there. Same road. Same shoes. Same pain.
Want to stay injury-free longer? Mix it up. According to a study, treadmill running actually creates less tibial stress than pounding pavement. That means trading one road run a week for a treadmill session might be enough to keep your shins from flaring up.
And let’s not forget trails. Uneven ground forces your body to engage stabilizer muscles in ways that road running never will. It spreads the impact, builds balance, and gives your joints a little breathing room. Back when I was ramping up for my first ultra, alternating road with trail kept my knees from buckling under the weekly volume.
Here’s what I often recommend:
- Swap a run or two: Got a tempo session midweek? Sub it with an easy bike ride or pool swim. Same cardio, way less stress on your legs. Runner’s World and Run Spirited both back this up: low-impact workouts help preserve fitness without adding damage.
- Trail or incline for long runs: Some weekends, instead of hammering 20K on concrete, I’d hit the trails or crank up the incline on a treadmill. It felt like a mountain session—minus the ankle-rolling rocks.
- Kill the boredom: Mentally, this stuff matters. I always look forward to a sunrise jog on the beach after too many soulless laps on the asphalt. Even elites use cross-training to get through marathon prep in one piece. You’ll see them on bikes, in pools, or hiking hills—because staying healthy is the secret weapon.
Bottom line: Mixing up surfaces and using cross-training doesn’t mean you’re slacking—it means you’re training smart.
When I’m in a high-mileage block, just swapping one run for a grassy jog or an easy bike spin keeps me going strong. It’s how you build volume without breaking down.
Your move: What surface switch could help you stay consistent this week? Treadmill Tuesday? Trail Saturday? Give it a shot.
Time-Based Runs: The Pace Break You Didn’t Know You Needed
Let me tell you a trick that saved my training when I was burnt out: I started running for time, not distance.
Sounds too simple, right? But it works. Studies show that when you run by time, your brain naturally holds a steadier effort. Run by distance, and your brain starts racing to the finish line—especially during that last stretch (Runner’s World has a good breakdown of this mental pacing shift).
Here’s what changed for me:
- Instead of chasing 10K every time, I’d say, “Just run 45 minutes.” No guilt if I felt sluggish. No pressure to “beat yesterday.” And weirdly enough, I started enjoying my runs again.
- I learned to run by feel—heart rate, breath, how my legs responded—just like legendary coach Harry Wilson taught his Olympic athletes. He had them run intervals by time so they’d tune in to effort instead of obsessing over splits.
Some real perks:
- Ditch the ego: When you’re tired, overtrained, or mentally fried, saying “I’ll jog for 30 minutes” feels way more doable than “hit 5K pace.”
- Steady effort = real progress: I’ve seen beginners get more consistent when they stop chasing distance. Running 40 minutes daily builds more fitness than hitting 7K once then ghosting your plan for a week.
- Mental wins: An hour on your feet, even at an easy pace, builds serious confidence. Trust me, that stuff stacks up.
Personally, I like to mix both approaches. Some runs I time. Others I measure in kilometers. But if you’re just starting out, or rebuilding after an injury? Time is your friend. Run the clock. Let distance take care of itself.
Try this: Set a timer for your next few runs instead of a mileage goal. What changed? Did it feel easier? Less pressure?
Listen Before It Breaks: Early Signs You’re Overdoing It
Your body doesn’t just suddenly fall apart. It whispers first.
Ignore those whispers? You’ll be hobbling for weeks. I’ve learned that the hard way. A few twinges in my hip turned into a full-blown shutdown because I thought I was being “tough.”
Here’s what to watch for:
- Nagging tightness or soreness – If that ache in your shin sticks around more than a day or two, it’s not “just tightness.” Ice it. Rest it. Cross-train. It’s way easier to prevent injuries than to fix them.
- Weird form changes – Limping? Shuffling? Posture off? Don’t run through it. That’s your body compensating for a problem.
- Crashing performance – If your normal pace feels like a death march and every workout feels harder than it should, you might be pushing too far into the red.
- Heart rate spike and crap sleep – Keep tabs on your resting heart rate. If it’s suddenly 8–10 bpm higher than normal, that’s a red flag. And if you’re tossing all night for no reason? Something’s off.
- Mental burnout – That dread before a run? The urge to skip “just this once”? It’s not laziness—it’s often a cue that your body needs recovery.
And here’s the kicker: missing one run is always better than missing three weeks. In fact, Runner’s World notes that swapping a painful run for a walk, bike, or swim session keeps you fit while letting the damage heal.
I live by this now: If it doesn’t feel right, it probably isn’t.
You’re not “soft” for taking a rest day. You’re smart. Elite runners pull back all the time to extend their careers. Trust your gut, and respect the signs.
