Event Description

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. Add in the changing aspen leaves and the (usually) perfect fall weather and you've got yourself one hell of end-of-the-season race. As an added bonus, the course shares some similarities with the High Lonesome 100 course and is put on by the same folks at Freestone Endurance.

The race starts on Sunday, September 26th, 2021 at 8am and runners have 10 hours to complete the course. There are three aid stations (not counting the Start/Finish) that are fully stoked with the typical aid station fare as well some tasty treats to surprise you and water and Tailwind are available at all aid stations. Runners can camp at the start/finish line for $10/night and space is limited to 35 spots. The race is capped at 150 runners and registration is $140 no matter when you sign up. Runners get an award, shirt, free full resolution professional images, and free drinks (alcoholic and non) at the finish line.

As an added challenge, runners can attempt the Sawatch 50/50 by registering for the West Line Winder 50k on the same weekend! Finishers of the Sawatch 50/50 will get a special award and place awards for the top 3 overall men and women.
