Just curious. I follow a lot of pros on strava, ans John Korir will run really slow on warm ups, cool downs, and wasy runs. And of course really fast on his workouts.
Some American pros hardly ever go slower than 7 minute miles, even while cooling down.
Has this been studied more as to what is more effective? Does anyone think John Korir would be better if he sped up his easy runs, or Connor Mantz would be better if he slowed down his easy runs?
