IRONMAN Montana
About the race
Every mile of IRONMAN Montana is shaped by the spirit of Big Sky Country. From the banks of the Missouri River to the expansive landscapes that define this region, athletes will race through a setting where adventure, endurance, and discovery come together. The course showcases the rugged beauty, wide-open spaces, and authentic character of Montana.

The 26.2-mile, two-loop run course follows the banks of the Missouri River, culminating in a finish near Elks Riverside Park, adjacent to IRONMAN Village and transition in Great Falls.
