Taking place in the pristine heart of one of Idaho's prettiest areas, this race—recently moved to late summer—always fills quickly. Coeur d’Alene is a classic resort and vacation destination that offers numerous recreational activities. The glacier-fed lake, surrounding forests and parks, the Trail of the Coeur d’Alenes and the Coeur d’Alene Resort Golf Course’s floating green are just a few examples.

Athletes begin their day with a two-loop, 2.4-mile swim in the clear waters of Lake Coeur d’Alene. The challenging two-loop, 112-mile bike course boasts no turns in an 80-mile stretch. The run loops along the shores of the lake blending the energy of a small town resort atmosphere with a world-class course. The single transition area and multiple loop course at the "hot corner" make IRONMAN Coeur d’Alene a favorite among athletes and their friends and families.
