Teton Dam Marathon 2027

The Teton Dam Marathon begins near Madison Jr High School in Rexburg, Idaho. Its out-and-back course is linked to the Teton Dam break site. The event offers a USATF-certified marathon, alongside half marathon, 10k, and 5k races, catering to both long-distance runners and those seeking a shorter race. The course winds through farmland and open spaces outside Rexburg. Runners encounter several uphill sections early on, with another rise around the halfway mark, gaining over 300 feet in a few miles. The half marathon crosses the Teton River twice, between miles 3-4 and again near mile 8. The route's history is tied to the Teton Dam break, which flooded Rexburg, with the race incorporating that landscape into its narrative.
