Event Overview

The Longest Dam Race takes place in Fort Peck, Montana, utilizing the infrastructure of the Fort Peck Dam and the surrounding recreation areas. The event features a variety of distances and disciplines, including running, walking, and cycling. Most routes begin on Hwy 24 near the dam shaft houses at the top of the structure, providing participants with views across the water and the surrounding landscape as they move toward the finish line at Kiwanis Park.

Distances and Course Details

Participants can choose from several specific event categories:

  • 10k (6.2 Miles): A run starting at the top of the dam with a turnaround at the midpoint.
  • 5k Run (3.1 Miles): A running event starting atop the dam and descending to the park.
  • 5k Walk Only (3.1 Miles): A walking-specific event following the 5k course profile.
  • 10 Mile Novice Bike Race: A cycling event requiring helmets and proper footwear.
  • 1 Mile Run/Walk: A shorter route on a nature trail near the Kiwanis Park Amphitheater.

The courses for the 10k, 5k, and bike events involve a transition from the asphalt on top of the dam to a gravel and dirt road section. This segment includes a gradual drop in elevation of approximately 350 feet. The final half mile of these routes returns to an asphalt surface before finishing in front of Kiwanis Park.

Important Participation Rules

Specific safety and equipment regulations apply to all participants. Cyclists must wear helmets and are prohibited from wearing flip-flops during the bike race. For the 1 Mile event, personal vehicles are not permitted at the starting area; instead, organized bus transportation is provided from the group site, though participants may also walk or bike to the start. Pets are not allowed at the event. Visit the organization's website for the most recent information.
