I raced against those bikes (250s) here in california, they were raced at willow springs in Rosamond (high desert) not as high as a mile high, but still up there. We are allowed to pull the snorkel but it didnt make much of a difference really. I ran a 1:41.3 and weigh around 170 (without gear), the track record is a 1:40.07 by a guy that weighs 135 (without gear). So as the saying goes, LBs equal HPs!! And I'm just curious, how much do the "fast" guys weigh up there, as that seems to be the biggest issue. Need to know how much to starve myself before Oct 8th for round 8. :wink:
