Prepare for an unforgettable journey into the heart of the Colorado Rockies at The Great Divide Ultra on June 6, 2026, in Divide, CO. Hosted by Revenant Running, this premier early-season ultra running festival offers challenging 100M and 100K distances, along with 50K, 25K, and even a unique Dark Divide Night Run, creating an engaging atmosphere for runners of all levels. The race takes place entirely within the stunning Mueller State Park, where you'll navigate 100% smooth single and double-track trails, experiencing rolling meadows, impressive Pikes Peak granite formations, and sweeping mountain vistas. The 100-mile course, comprising six 14.8-mile loops and one 10.5-mile loop, features an elevation range of 9,189' to 9,743' with an approximate total gain of 16,071 feet, while the 100K boasts around 8,500 feet of elevation gain.

Known for its exceptional organization and vibrant community spirit, The Great Divide Ultra has a reputation for being a runner-centric event, having sold out for two consecutive years. Typical race day conditions in early June offer pleasant running weather, with highs around 68°F and lows near 37°F, though a 9% chance of precipitation means runners should prepare for varied conditions, including the possibility of rain or even snow at higher elevations. The looped course design ensures excellent crew access and features well-stocked aid stations, spaced every 4.3 to 6.1 miles, offering everything from Tailwind and Muir Energy gels to warm food, and allowing for drop bags. Pacers are permitted for 100M and 100K runners, further enhancing support on the course.

The start and finish line for the 100M, 100K, and Night Run is conveniently located at the Livery/Equestrian parking lots, making it ideal for support teams. Finishers of the 100M and 100K races earn a coveted belt buckle, along with a gender-specific race shirt, BOCO Trucker Hat, personalized bib, and a post-race meal, ensuring a rewarding experience after conquering Colorado's majestic landscape. With a generous 36-hour cutoff for the 100-mile distance, The Great Divide Ultra welcomes both seasoned ultrarunners and those looking to test their limits on a stunning, non-technical course.
