None of us are perfect runners. I’m not, you’re not—and that’s okay. But some training mistakes show up again and again, no matter if you’re brand new or chasing a Boston Qualifier. The good news? They’re all fixable.
After reading a recent piece from Runner’s World where coaches shared their biggest pet peeves, I found myself nodding along. These are things I see with many of you, too. So here’s my quick take on the five mistakes—and what you can do instead.
1. Running Every Run Too Hard
If every run feels like race day, you’re missing the point. Easy runs are where your aerobic system actually gets stronger. They should feel so relaxed you can hold a conversation. Slow down on your easy days, so you have energy to actually run fast when it’s time.
2. Ignoring Your Current Fitness
Too many runners train for their goal pace instead of their current fitness. That’s a recipe for injury or burnout. Use your last race (or a mile time trial) to set training paces. Training is about progression—start where you are, and the fitness will build.
3. Over-Relying on Data
Watches are great, but don’t let them run the show. Learn to listen to your body—breathing, rhythm, perceived effort. Sometimes the best thing you can do is ditch the watch for a run and reconnect with feel. On race day, your body—not your Garmin—gets you to the finish.
4. Letting Peer Pressure Pick Your Races
Just because your friends are running a marathon doesn’t mean you should. If the thought of training excites you, go for it. But if it feels like a burden, it’s okay to say no. Running should come from your own goals, not someone else’s Instagram post.
5. Disrespecting the Training Plan
Training plans are designed with balance—hard days, easy days, recovery. When you skip runs, cram workouts, or go rogue, you throw that off. Consistency matters more than perfection. Missed a run? Don’t panic. Just move forward and trust the plan. And if you’re working with me—tell me! Communication is part of the process.
Bottom Line
Running is simple, but it’s not easy. Respect the process, trust your plan, and listen to your body. Fixing these small mistakes can help you stay healthier, run faster, and—most importantly—enjoy the miles.
