Course Highlights
The Sage Burner Trail Race takes place in the Hartman Rocks Recreation Area just west of Gunnison, Colorado — a landscape utterly unlike the classic Rocky Mountain high-alpine environment. Here the hills are covered in sage brush and the terrain alternates between technical slickrock, smooth flowing singletrack, and doubletrack roads built for speed. The course is described as ‘deceptively tough’ — rolling hills and punchy climbs in a high-desert climate at approximately 7,700 feet elevation. From the ridgelines, runners are treated to extraordinary 360-degree views spanning the Maroon Bells, the San Juan Mountains, and the entire Gunnison Basin.
Race Details
The 2026 Sage Burner is scheduled for Saturday, October 3. Distances include the signature 50K and a 15K option. Parking at the Hartman Rocks base area begins at 6:45 AM on race day. Gunnison is located approximately 2 hours east of Grand Junction and 3 hours west of Denver, making it a destination race that rewards an overnight trip. The proximity to Black Canyon National Park makes for an excellent weekend adventure.
Why Runners Love It
The Sage Burner is beloved for offering a genuinely different trail running experience from the mountain-heavy Colorado racing calendar. The Hartman Rocks terrain — with its desert-influenced sage and slickrock — channels Southwest trail running aesthetics in a distinctly Colorado setting. The October timing brings cooler temperatures and often brilliant autumn light over the Gunnison Basin. It’s one of Colorado’s hidden-gem trail races, drawing a devoted community of trail runners who prize terrain quality over event spectacle.
Race Weekend Tips
October at 7,700 feet in Gunnison can be cold — mornings may be in the 30s°F with afternoon temperatures reaching the 60s°F on a clear day. Bring layers for the start and a wind shell in case conditions change. Gunnison is a small town with limited accommodation — book lodging well in advance, especially if visiting during fall foliage peak. The Black Canyon of the Gunnison National Park is just 15 miles away and worth adding an extra day for hiking.
