Boulder, CO
This challenging course includes nearly 2300 vertical feet of climbing. A mixture of dirt roads, fun winding single track, and some technical trail running, the course has a little of everything, including a creek crossing and small ladder to climb. It showcases Boulder County's mining history, the regrowth of a forest after a fire, and fantastic views. Starting and finishing at the Cal-Wood Lodge, this run is entirely on private property and these trails are only accessible to the public on race day.
