The Great Divide Ultra

The Great Divide Ultra

Join us for a full weekend of trail running at the Great Divide Ultra! The popularity of the event has allowed us to fill both Saturday and Sunday! The Great Divide Ultra has sold out three consecutive years, so get registered now! Please be aware of the event date when registering.

New in 2025: All 50k and 25k (excludes Dark Divide) runners and crew will be required to park at the John Wesley Ranch. The shuttle ride from the ranch to the start/finish line is approximately 6 minutes. Vans will be shuttling runners and crew to and from the ranch throughout the day.

Experience the spring-fed meadows, massive rocks of Pike Peak granite, and sweeping views of Colorado’s most spectacular mountains in the Great Divide Ultras. This early season 100 mile, 100k, 50k, and 25k event takes place entirely on the beautiful rolling meadows of Mueller State Park. The course is 100% smooth single/double-track trail.

Dark Divide Night Run

As a part of the Great Divide Ultras running festival, we are introducing the Dark Divide Night Run! This night run begins at 8:00PM as the sun is setting on Saturday June 7th. This incredible run offers runners an opportunity to share the trail with the 100mile/100k runners and to practice running through the night.
