Here’s the thing.
Mileage says literally nothing about potential.
Some 800 runners can’t tap into their potential until they are running over 70 mpw. Some 800 runners are world beaters with 35 mpw.
Some 8k-10k runners can’t run more than 70 without suffering injury or burnout. Some equally fast 8k-10k runners lose fitness if they stay under 70 mpw.
I know this is nit-picky and not the point of the post, but we live in an age where we’ve come to realize slamming mileage isn’t always the best, and mileage is just one factor of many.
Me and a teammate from highschool and now college both were picked over faster runners to have a spot on the team. The reason for this being that we both were significantly faster than anyone from our HS team currently or from past years, while those runners from the other teams were pretty average.
I guess what I’m saying is that a sub 4:30 guy looks better than a sub 4:25 guy when the 4:30 guy is 30 seconds faster than anyone on his team, and the 4:25 guy is barely top 5. Time wise, both have a place in collegiate running, but one shows a well trained athlete while another shows a quite possibly poorly trained athlete that can still produce almost the same times.
Even with just under a year of actually smart (not necessarily higher mileage) training, I’ve gotten a lot faster than the guys that were on my level in highschool, and caught up to the guys I used to think were untouchable.
That being said, if the margin is bigger, say 4:10 vs 4:25, obviously you’d want to take the 4:10 guy. Even if the 4:25 guy has a ton of potential, that’ll still probably look like 4:00-4:05 vs 4:10-4:15 in a couple of years.
