Nestled between Yellowstone and Glacier National Parks, this beginner-friendly event lets you swim in a scenic spring-fed lake, bike on recently rebuilt two-lane roads with sheriff support, and run a flat, fast trail course while enjoying wonderful people and stunning scenery. You can choose from triathlon, aqua-bike, duathlon, or super sprint distances, with a virtual option available for $30, and all participants receive a finisher's medal, shirt, and post-race meal with age group awards. A 5K fun run is also offered as a charity fundraiser, with proceeds supporting local organizations like the Prickly Pear Land Trust and Helena Food Share.
