Horseshoe Bend Ultras

Running through Arizona's breathtaking landscapes, the Underground Runner series offers an unforgettable experience for endurance athletes. Participants can choose from three distances: 50 miles, 55 kilometers, and a half marathon, each providing unique challenges and scenic beauty.
The 50-mile race takes runners on a journey across desert sand and slickrock terrain to reach Antelope Canyon and Horseshoe Bend, two of the most photographed landmarks in the country. The route then transitions into smooth single-track trails around Page's plateau before finishing with stunning views of Lake Powell and Glen Canyon Dam.
The 55K course features an awe-inspiring journey to Horseshoe Bend, navigating challenging desert landscapes en route. Runners will enjoy a final loop around the city’s plateau on fast and runnable terrain, offering panoramic vistas of Lake Powell and Glen Canyon Dam as they near the finish line.
For those seeking a more manageable distance, the half marathon offers an exhilarating ascent and circumnavigation of Page's plateau with smooth single-track trails that wind through scenic landscapes. The route provides breathtaking views of Lake Powell and Glen Canyon Dam throughout its entirety.
