Here is mine from 30 years ago, and it is still one of the most beautiful rides I've done. It starts and finishes southwest of Colorado Springs in Penrose Colo. It is about 110 miles from Penrose, but an even 100 if you start/finish in Florence. Ride south from Florence and up Hardscrabble Pass, from the pass the views of the Sangre de Christo range will take your breath away (so will the 10,000 ft elevation), have lunch in the town of Westcliffe. This is a classic Colorado ride, I rode it many times, always enjoyed it!

There is a hot springs in Florence, that was always nice after this ride!
