Your pace is slowing

Your aerobic zones have shifted after 50 - and if your training hasn’t shifted with them, your pace will feel harder even at the same effort.

You're picking up more injuries

Tendon and muscle resilience naturally change with age, making knees, calves, hamstrings, and Achilles more vulnerable if strength and pacing aren’t aligned.

You’re more fatigued

Your recovery system isn’t keeping up with your training load - causing fatigue to build faster, recovery to slow down, and runs to feel harder.

The Problem?

Most runners don’t know which one is really holding them back.
