Why we'd pick it
- Serious climbing — 4572 m of gain. Respect the cutoffs.

The course
This is a 100-mile out-and-back from Leadville over Powerline, Sugarloaf Pass, the Colorado Trail, Twin Lakes, and Hope Pass twice. The start sits near 3,109 m and the course totals more than 4,572 m of gain, with its high point at roughly 3,810 m. The 30-hour cutoff leaves little room for a bad stomach, slow river crossing, or altitude spiral.
