I'm planning to start out on the CDR going north from South Fork Colorado to ride the track up Steamboat Springs. A general question to anyone that can answer: where are the most challenging bits of this track in Colorado? Please note, I'm not asking where I'll have trouble because that would require some knowledge of our riding skills and what we're riding. We're pretty experienced off-road on KLRs and 690 Enduro. I'm just trying to get some idea of miles we'll ride each day and where people, in general, are finding the challenge in the that part of the CDR. We're starting the ride this Friday. When we get to Steamboat, we'll turn around and head south on the COBDR back down to Cortez. We're looping in that direction thinking it'll put us in the San Juans mid-week vs. the weekend if we go there first (traffic avoidance in the Alpine Loop area).
