Hi all. I'm from California with 25,000 RUSA k's to my credit and 2 PBP's, a pair of Cascades, a Rocky Mountain, and GRR as my 1200k's done. I keep coming back to do "just one more". I have never done a 1200k at high altitude, however. I know some of you from the Bicycling LD forum, but I pretty much quit posting there.
On my calendar for this year's folly is the Colorado High Country 1200k. I live near sea-level and have no high-altitude training available until mid-June and the CHC is in early July. Most of it is above 6000 ft and the route has some long grades that go up to 10,000 ft. I am not a fast rider either. My average time on the rides mentioned is about 88 hours. I do get in good sleep breaks, good being about 10-12 hours total or 3-4 hours each night of the ride.
Any ideas, other than purchasing the "high altitude sleep chamber" or selling everything, quitting my job and moving to Lake Tahoe, to help me get ready for this?
