Having done RTR twice - many years ago - I have some concerns about "flatlanders" from low elevations coming to CO and then having just ridden a 12,000 foot pass, generally not expecting what turns out to be a very cold night with frost and likely not-sleeping well in crowded and cold tent facilities or a poorly ventilated and crowded gym, then attempting another 12,000 foot pass the next day.

I don't know the particulars of this situation, and it may not fit the above scenario, but I do know there have been many serious accidents, some critical, and a number of deaths over the years on RTR. I witnessed one myself, when a rider went down in a crowd in front of me, breaking her pelvis.

I don't, however, know the solution (if one is required).
