Embark on an unforgettable desert running adventure at the Arches Ultra, set against the stunning backdrop of Moab, Utah, on January 31, 2026. This premier event, part of the acclaimed Run Moab Series and a cornerstone of the Triple Crown of Moab, offers a range of challenging distances including a 50M, 50K, Half Marathon (13.1M), and 9K, ensuring a perfect fit for every trail runner.

The Arches Ultra course is renowned for its diverse and captivating terrain, traversing the Bar M, Klonzo, and Klondike Trail Systems along the border of Arches National Park. Runners will navigate a dynamic mix of smooth, easy trails, groomed singletrack, technical slick rock, and even some sandy sections, providing a comprehensive test of skill and endurance. While the elevation is generally lower, the courses feature engaging rolling hills, with the 50M boasting a 4,524-foot elevation gain and the 50K ascending 2,894 feet, offering magnificent views without the strain of high-altitude running. Beyond the varied footing, runners are treated to breathtaking vistas of towering Moab cliffs, the iconic Arches National Park, and the distant, snow-capped La Sal Mountains, with the unique thrill of passing ancient dinosaur tracks in Utah Raptor State Park.

Historically, typical race day conditions in late January present crisp highs around 47F and lows around 22F, with a minimal 3% chance of precipitation, creating ideal cool-weather running. Aid stations are strategically placed throughout the courses, offering a generous array of water, electrolytes, gels, sandwiches, chips, and even hot apple cider, all supported by a cupless policy encouraging runners to bring their own reusable cups. Organized by the highly regarded Mad Moose Events, the Arches Ultra provides a well-marked course and a supportive atmosphere, consistently earning praise from runners for its outstanding views, challenging elements, and overall exceptional experience. All races begin and conclude at the Gemini Bridges Trailhead, just north of Moab, with carpooling strongly encouraged due to limited parking.
