Weeklong MTN Bike trip at altitude

[wvbrad]

Hello,

Does anyone have any suggestions on lessening the effects of altitude? I'm coming from sea level and going to Durango and biking out of Purgatory for a week in the Colorado high country. We'll be biking at 9-12,000' all week, but sleeping around 8,700'. I'm going into this week hydrated, but other than that what else can I do? Any thoughts on taking Diamox? Race day boost?

Thanks in advance!

Brad
