This Rockies classic offers three distinct courses traversing Big Sky’s diverse terrain, from Town Center to the slopes of Big Sky Resort. The event has grown steadily, drawing over 400 mountain bikers across 15-, 30-, and 60-mile options, with all proceeds split between Big Sky Community Organization and the Southwest Montana Mountain Biking Association.

The 60-mile course delivers the full Big Sky experience with 58 miles and 8,600+ feet of climbing on over 85% singletrack. Recent updates include new sections through the Spanish Peaks neighborhood, the technical Poop Chute singletrack, and a first-time descent of Otter Slide. You’ll tackle the Yellow Mule loop in reverse direction—the way locals ride it—climbing First Yellow Mule before descending Second Yellow Mule. The route encompasses Mountain to Meadow, Fish Camp, and the classic town finish via Ralph’s to Uplands to Hummocks.

The 30-mile option covers 33 miles with 4,400 feet of climbing, also predominantly singletrack. It features the same Spanish Peaks addition that eliminates the pavement climb to Fish Camp, plus Mountain to Meadow and Fish Camp before the town finish.

The 15-mile beginner-friendly course showcases the best town trails with most climbing front-loaded on pavement, though Ralph’s Pass delivers one heart-rate-spiking switchback section.

Bear safety is paramount—both black bears and grizzlies frequent all routes. Organizers partner with HEY BEAR for bear spray rentals, especially valuable for out-of-town participants. A $3,600 purse rewards top finishers in the long course, while Stio products go to the top five in each category.
