They are both fast guys. David was in the Olympic Marathon Trials and came in third last year at this race and Zach won the 50k version of this race last year. David was in the Western States this past summer and bombed so this might be a redemption run. Zach has never raced a 100 miler so it will be interesting. They both run for Nike Trail and are both hipsters. It will be a great race.
166 km, 9600m in elevation, in the alps, they have to carry an emergency pack with them
this is the same race that Sage broke his knee on last year and was helicoptered out
