I think it's even slow for high schoolers. I didn't practice that much and ran 100m in 12.5s from rest at my peak. 4s slower is snail pace. I think most in my class could run that fast (or slow).
At my peak, I finished the NYC Marathon in the top 2%. I still finished 45 minutes behind the winner.
It feels like elite athletes aren’t even competing in the same sport.
