Mastering,
No, last year 8:50s. The race started in pouring rain, the field was bunched for a very slow first mile. The last 800m was fast, I did not have a time on it. Last year went in about 8:50, that chap won the Mountain West 10k a week or two ago. The winner from 2014 ran 8:52 during the season, I believe he ran 13:50 as a sophomore at Boise State.
Slagowski is pretty good, that is all I can say. Probably quite a bit better than some high school athletes over the last decade. Obvious statement from his times, but he is something special which will be evident soon enough.
