After some more digging, I found out that Ryan Bull, who is an Oredigger, ran a PR of 28:03 for an 8k at altitude. (His PR for an 8k at lower elevations is 26:46.) This was in the open race at the RMAC championships, won by Western State Univ. on both the men's and women's sides. This time would've put Ryan in 52nd place in the varsity race, which is pretty awesome!
Fantastic job Ryan, a 28:03 around Willis Case GC is not easy at all. i've golfed there and there are some hills there to be sure!
