Thanks for the great advice. I'm leaving WI on Wed, so we should be in CO by Thursday. I'm going to preride the course on Friday and race it on Saturday. Since I couldn't spend 1-3 weeks acclimating to the elevation (like I've read), I thought I'd get to the race later (two days before) so I wouldn't be so tired (like I've also read).

The race will be at 8000-10000 feet, it's 12 miles in distance and 2400ft of climbing. It will be interesting.....since mountain biking is such an anerobic sport...then you add the elevation factor on top of that. It should be fun, if I don't puke!
