La Veta, Colorado (United States of America) - "Wild Wahatoya Runs". Come join us to run through a magical part of history in the Cuchara Valley.

The Ute, Comanche, Apache, and other, earlier Native American tribes held the peaks in religious awe and named the mountains Wahatoya, meaning — Breasts of the Earth.— Our event will be pairing with both the town of La Veta and Cuchara to help them celebrate their annual October Fest. We will have a 50K, heavy half marathon, and 8ish mile event.

Winter Park, Colorado (United States of America) - "The Elevation Everest Race". The Elevation Everest Race is an endurance event held at Winter Park Resort in Colorado, focusing on elevation gain rather than distance. The goal is to accumulate either half or the full elevation of Mt. Everest. Participants can race solo or form a relay team with friends to divide the total elevation gain. Athletes race up the mountain, ride the gondola down, and repeat until they summit. The Half Everest race involves 10 laps up the mountain, over 14,516 feet of elevation gain, 22 miles, and allows 17 hours to finish. Looking for an even bigger challenge? Take on the Full Everest—19 laps up the mountain, over 30,000 feet of elevation gain, 42 miles, and the same 17-hour time limit. Backed by industry-leading sponsors like Garmin, La Sportiva, Gorewear, and Runners Roost, Elevation Everest is one of Colorado's fastest-growing endurance races and was voted "Endurance Event of the Year" for both 2025 and 2026 by the Colorado Event Alliance. https://www.elevationeverest.com
