If you’ve ever blown up in a race and thought, “what the hell just happened?” …yeah. Welcome.
You’re normal.
Pacing is one of those skills everyone thinks they have until the adrenaline hits, the watch starts yelling numbers, and you’re suddenly running the first mile like you’re trying to win an Olympic final.
I’ve messed this up plenty. So have my athletes. So has basically every runner I respect.
Because pacing isn’t just math.
It’s ego.
It’s emotion.
It’s the crowd.
It’s heat and hills and bad sleep and the stupid voice in your head that says, go with them, don’t be weak.
And the brutal part is this: you usually don’t realize you paced wrong until it’s too late. When the legs go heavy. When your breathing turns to panic. When your “comfortable” pace turns into survival shuffle.
So let’s call out the classic pacing mistakes — the ones that keep people stuck, tired, or constantly blowing up — and how to fix them without turning every run into a spreadsheet.
1. Starting Like You’re Shot Out of a Cannon
We’ve all done it—first mile of a race or long run, legs feel fresh, energy’s high… and BOOM, you’re out way too fast.
“I felt great the first 10 minutes… and then I blew up.”
Sound familiar?
Even going out 15–30 seconds too quick per mile can wreck your day. You’ll feel fine early, then hit a wall and start bleeding time.
Fix it:
Start slower than you think you should. Let the overzealous runners pass. You’ll reel them back later when they’re walking and you’re still cruising. Remind yourself: if it feels too easy at the start, you’re doing it right.
2. Racing Every Damn Run
One guy in my old run group used to hammer every training run. I mean, tempo effort on recovery days. He was constantly injured and couldn’t figure out why.
“I thought if I pushed hard every run, I’d get faster.” Nope. That’s the fast lane to burnout.
Fix it:
Easy days are sacred. Run slow. Like, “I can sing the chorus of a song out loud” slow. Follow the 80/20 rule—80% easy, 20% hard. That’s how real gains happen. Save the fire for race day.
If you can’t trust yourself to slow down? Run with a slower buddy or ditch the watch altogether.
3. Comparing Yourself to Everyone Else
Social media makes this worse. You see your friend post 7:10 pace on their long run, and suddenly your 9:30 pace feels embarrassing.
Stop. Everyone’s on a different path. Different training, different goals, different bodies.
“I kept comparing my pace to my friends… it ruined running for me.” That’s a real quote. Don’t let that be you.
Fix it:
Compare your current pace to your past pace. Are you improving? Then you’re winning.
Someone else’s 6:45 pace has nothing to do with your 10:00 PR breakthrough.
4. Being a Slave to the Watch
Here’s the truth: running watches can’t account for heat, hills, headwinds, poor sleep, or rough days. But your body can.
Don’t force an 8:00 tempo just because the plan says so—if your body’s redlining, it’s too fast today.
“Forget the charts. Learn your gears.” That’s one of my coaching mantras.
Fix it:
Use pace as a reference, not a rule. If the effort feels off, adjust. And if conditions suck? Let the pace go. Effort-based training always wins long-term.
Try covering the watch face and just checking splits once per mile—or not at all. Get back in tune with your body. Train smarter, not stricter.
Pacing Mistakes: The One Nobody Warned You About
- Not Adjusting for the Environment. Here’s the deal: running isn’t done in a vacuum. Heat, humidity, hills, altitude, wind—even plain ol’ fatigue—can throw off your pace. And if you expect to hit your perfect splits no matter what, you’re setting yourself up to be frustrated or injured. Or both.
- Heat Reality Check. Running in 90°F heat? You’re gonna slow down. That’s not weakness—it’s physiology. For every 5°F above your comfort zone, expect your pace to dip by 20–30 seconds per mile. That’s normal. Hydrate. Adjust. Survive. Don’t be the hero who passes out trying to match their winter PR pace in a summer sweatbox.
- Smart hill strategy. You might crawl uphill and fly down—that’s fine. The goal is even effort, not even splits. Pace is a guide, not gospel.
Final Word
“Pacing isn’t math—it’s feel, feedback, and flexibility.” The best runners don’t obsess over their watches—they listen to their bodies and adjust in real time.
