Build my planThe Antelope Island Fall Classic has been a staple of the Utah trail running scene since the early 2010s, offering a late-season test across rolling desert terrain, ridgelines, and wide-open views of the Great Salt Lake. In 2026, the event expands with new distances, including a 68K featuring an out-and-back to the island’s high point, Frary Peak, and a 10-mile loop highlighting the singletrack around Bridger Bay.
With multiple distances and a growing festival atmosphere, the Fall Classic continues to evolve while staying rooted in what has always made it special: simple, scenic, and a perfect way to close out the season.
