This is a great ride. I've done the complete loop in 2 days ... Lake City over Engineer Pass to Ouray, Ouray over Imogene Pass to Telluride took about 11.5 hours .... Imogene is pretty brutal. Day 2 I took the Telluride gondola to the top and got on Prospect Trail to Boomerang trail and dumped into Alta Lakes .... to Ophir. Did Ophir Pass to Silverton. From Silverton took Cinnamon over to Lake City.... about 8.5 hours. Day 2 was much easier than day 1. Overall a top ride that I recommend to anyone.
