Race Information

A classic, high-alpine, vert-heavy Colorado 50k!

Get some miles on the Colorado Trail and run all the way to 13,150 feet in elevation! Starting and finishing at the base of Mount Princeton, runners are treated to panoramic views of the Sawatch Range and the gorgeous Arkansas River Valley. The race runs in a large lollipop and is essentially one long 7000' foot climb and one long 7000' descent. The beginning and end have a mix of dirt and paved roads, but the middle is 25 miles of uninterrupted singletrack, including 12 miles on the Colorado Trail. Yet, despite the amount of vert this course is surprisingly runnable, especially for a runner with mountain experience.

Runners will have 10 hours to complete the course. For the added challenges, you can attempt the Sawatch 50/50 by running the West Line Winder and the Sawatch Ascent over the same weekend. The Sawatch Ascent is put on by Freestone Endurance, the same folks who bring you the legendary High Lonesome 100.
