Course
The 10K Run starts at the Fort Peck Dam Shaft Houses on Hwy 24, runs across the top of the dam to a 3.1-mile turnaround, then descends about 350 feet on a gravel/dirt road and finishes on pavement at Kiwanis Park. The 5K Run begins atop the dam, follows the same gravel slope without the turnaround, and transitions to pavement to Kiwanis Park. The 5K Walk follows the same route as the 5K Run. The 1-Mile Run/Walk uses a fully paved nature trail at Kiwanis Park and is flat. The 10-Mile Novice Bike Ride starts at the top of the dam, crosses and returns, then continues past the start and descends toward flatter terrain to finish at Kiwanis Park. All events finish at Kiwanis Park. Visit the organization's website for the most recent information.
