The Great Divide Ultra

The Great Divide Ultra is a popular trail running festival that offers various race distances including 100 Miler, 100K, 50K (Saturday, Night, Sunday), and 25K (Saturday, Night, Sunday). The event has a history of selling out quickly, so early registration is encouraged.

In 2025, all 50k and 25k runners and their crew will be required to park at the John Wesley Ranch, with a shuttle service provided to the start/finish line.

A new addition to the festival is the Dark Divide Night Run, kicking off at 8:00 PM, which allows participants to share the trail with 100 mile and 100k runners during the night.
