These 3 Run Form Myths Almost Ruined My Marathon

My form was fine… until I ran slower.

Form breakdown doesn’t always happen when you're tired—it can hit at your "comfortable" marathon pace. In this episode, I break down how a mild hamstring strain led me to reassess everything I thought I knew about run form. You’ll hear how I tested drills, cadence changes, and strength work to fix overstriding and avoid heel striking without interrupting training. If you're working toward a sub-3 marathon or just trying to stay healthy through long-distance training, this is your blueprint.

Key Takeaways

1. Fixing form isn’t about one quick tip—it’s consistent drills and strength work.
2. Slower running doesn’t always mean better running; form can break down at marathon pace.
3. Heel striking isn’t always bad—overstriding is the real problem.
