Brett Maune proposed the challenge ("hard" version):

A couple years ago I ascended the tallest peak in each of the three prominent SoCal mountain ranges (Baldy, San Jacinto, and San Gorgonio) via 'hard' routes. The stats are roughly 22k ft gain and 50 miles in 21 hours 56 min. Details of the route and trip can be found here:

The "Five Peaks Traverse" is a mountaineering project that links the summits of Mt. Bachelor, Broken Top and South, Middle and North Sister in the Cascade Mountains of Oregon.
