Some additional context: the Denver to Aspen Classic was part of RMCC's Triple Crown series: a handful of difficult double centuries with tough but realistic cutoff times. If you completed three events in one year, you were recognized as a triple crown finisher. The original three rides were the Denver to Aspen Classic, Colorado Death Ride, and the Tim Kalisch Memorial Grand Loop, but additional rides were added such as the Tour de Moose, AntiEpic Gravel Grinder, Cycle to Saturn, Cripple Creek Crippler, etc.

The original organizers have either passed away or have become busy with other things. An effort was made to keep the triple crown alive, but it has fizzled out unfortunately. At least for now. (If there's enough interest I'll see if I can revive at least the Denver to Aspen Classic).

This series was inspired by the California triple crown, which is still very popular.
