Winter Park Hill Climb

Wow, so i guess i am not a climber- i just got my butt kicked at the hill climb in winter park. it starts at 9,000ft and it climbs up service roads for 5 miles to Mary jane ski area, to over 11,000ft. i heard the view up top was cool, but i just went through the finish, and immediately turned around and rode back down. i know, i shouldn't be such a sore looser, but i felt like i was going backwards and everyone passed me after the start. i pulled my way back up to 6th, but i didn't feel very good. i figured that i needed a good warmup for this, so i rode for about 2 hours before. didn't help. i am the kind of rider that always has a better second half of a xc race- so i am blaming it on the fact that if i had another 5 miles or 2,000ft, i could have won. just kidding. but seriously, i am hoping i was just having a bad day, and that i really am ok at climbing. really.
