; in the interview below he refers to threshold ten milers at 5:20 at lower altitude and 8 miles at 5:26 at Big Bear). His senior year he was held back by side effects of Accutane treatment. In college, he ran no faster in the 1500m but finished 2nd as a junior in xc to Ritz and won NCAA's in the 5000m in 13:22 as a senior.
"HALL: I see myself as being very good at all of the distances, but I really like the mile the most. It’s what I’m the most passionate about, but I see myself as a good cross country runner as well. Hopefully, when I go to college I’ll do well in cross country which I think I’m pretty good at. I think I’ll do well at the longer distance (10k in college versus 5k in high school) because I’m doing 10 mile threshold runs now so 10k should seem shorter than that.
LETSRUN: What type of pace are we talking about for these threshold runs?
HALL: It depends on where and when I do them. I did one at 5:20 pace at lower altitude. Up here (in Big Bear), I did 8 miles at 5:26, but I’m getting stronger and stronger every week."
