Runners from all over the country will be in Rexburg, Idaho on the first Saturday in June to participate in the Teton Dam Marathon & Races. The races include a marathon, half-marathon, relay, 10K, 5K, and Kids Race. The Teton Dam Marathon & Races takes place every year around the anniversary of the breaking of the Teton Dam.

On June 5, 1976, the collapse of the Teton River Dam unleashed a savage flood which caused $500 million in damage, took eleven lives, and made thousands homeless in Wilford, Sugar City, Rexburg, Salem, Hibbard, Firth, Blackfoot, and Roberts.

This tragedy was turned into triumph by the victims’ own faith and courage and by an outpouring of aid by many volunteers from Idaho and nearby states. For this reason, hundreds of runners flood the streets to take on their own personal challenge of running a race.

This year's Teton Dam Marathon will be on June 7th, 2025!
