Ultramarathons in Buena Vista

Sunday, May 3 · Buena Vista, Colorado

The Collegiate Peaks Trail Run 50 Miler is an out-and-back course starting and finishing in Buena Vista, Colorado, set for early May when mountain weather can still be unpredictable. At roughly 50.6 miles due to course rerouting, runners have until 6:30 pm to complete the challenge, with a mandatory 12:15 pm cutoff at the turnaround point around mile 25. The course runs through Colorado's high country terrain, though specific elevation details aren't readily available. Expect typical mountain trail conditions with potentially variable spring weather — snow, rain, and sun are all possibilities in early May at altitude. Runners tackle the route entirely self-supported except at the turnaround, where crews are permitted, and trekking poles are allowed only on the return loop for 50-milers. This race suits runners comfortable with mountain terrain and changing conditions who don't mind the uncertainty that comes with early season Colorado racing. The no-crew, no-pacer policy until the turnaround emphasizes self-reliance, making this a good fit for experienced ultrarunners who prefer a more traditional, less supported race format.
