For a long time, I had one pace.
Not race pace. Not easy pace.
Just pace.
Every run became a challenge. If I ran a certain pace yesterday, I wanted to beat it today. Even my recovery runs slowly turned into workouts.
I thought I was working harder than everyone else.
What I was actually doing was making myself tired all the time.
Eventually I hit a wall. My workouts weren't improving. My legs constantly felt heavy. I was showing up to hard sessions already fatigued from trying to run fast on days that were supposed to be easy.
That's when I finally learned the purpose of an easy run.
Easy runs aren't there to test your fitness. They're there to build it.
Once I slowed down, everything else improved. My workouts got better. My long runs felt stronger. Recovery became easier. My body finally had a chance to absorb the training instead of constantly fighting fatigue.
These days, if my easy run feels a little too easy, I know I'm probably doing it right.
