So back to the idea of the Great Divide solo. Yes it is a remote area. But is there enough bicycle traffic, or other, to get out of a tight spot should a problem arise? I'm thinking a severe mechanical problem is more likely than a severe medical problem. More likely to break a derailleur than an arm or leg. I do understand the point of travel in a pack of 3. But necessary? I would seriously consider a spot if doing it alone.
