Overview

There's over 22,000 feet of elevation gain on this loop, with a high point above 13,000 feet. You'll get to run on the Colorado Trail, Continental Divide Trail, and over multiple alpine passes. It generally flows counter-clockwise, starting a little below 9,000 feet, climbing to the high point of the course within the first 16 miles and then one 12 mile out-and-back section before continuing the loop.

You won't drop down below 9,000 feet until the last quarter of the course. Bring your strongest legs, biggest lungs, and be ready to view some of the most scenic singletrack you've ever seen.
