It's got a lot of great insight including how Hall's buildup before his 2:04 was awful but this was quote stunned me.
It's an interesting thought. Hall was a 3:43 guy in HS and he's a better marathoner than miler.
“He was essentially a 4:00 miler in high school and the Mt. Sac cross country course record holder. Irv sent me his workouts. They were at a very high level. I think he could have run close to a 2:10 (marathon) in high school. I had an athlete, Steve Ortiz, who ran 2:13 as a college junior, and Ryan was doing harder workouts in high school. And when he was at Stanford they ran hard, because of all the talent that was there.
But a 2:10 marathon is way out there. I guess "close to 2:10" might be 2:12. But 2:12 is equivalent to like a 3:54 mile according to JK.
What did Gompers run? What's the US high school record?
What do you think Hall could have run for 26.2 in HS?
