Longest Dam Race

Embark on an unforgettable journey at the Longest Dam Race, set for June 20, 2026, in scenic Fort Peck, Montana. This unique event invites runners of all abilities to traverse the iconic Fort Peck Dam, offering breathtaking views and a truly one-of-a-kind experience. Choose your challenge from distances including 10 miles, 6.2 miles (10K), 3.1 miles (5K), and a 1-mile fun run/walk, promising an exhilarating day filled with community spirit and stunning natural beauty.

The longer distances, including the 10K, kick off at the Fort Peck Dam Shaft Houses on Highway 24, leading participants across nearly the entire length of the colossal Fort Peck Dam—the fifth largest earthfill dam in the world. Runners on the 10K course will reach a 3.1-mile turnaround before embarking on an approximate 350-foot gradual descent. This thrilling section combines gravel and dirt roads, eventually transitioning to asphalt for a strong finish at Kiwanis Park. The 5K run and walk options also begin atop the dam, skipping the turnaround and heading directly down the scenic gravel slope to the paved finish line at Kiwanis Park.

For those seeking a more relaxed pace, the 1-mile fun run/walk offers a flat and friendly course entirely on a paved nature trail within Kiwanis Park. Typical race day conditions in late June bring comfortable highs around 79°F and lows around 54°F, with only a 10% chance of precipitation, creating ideal weather for an inspiring race day. Established in 1996, the Longest Dam Race is a beloved annual tradition, promising vast views and an engaging course for every participant.
