The Coeur d'Alene Triathlon and Duathlon is one of the most scenic races in the Northwest. The 1.5k swim takes place in Lake Coeur d'Alene. A 40k bike ride goes down Coeur d'Alene Lake Drive, and leads to Mullan Trail Road for a challenging uphill course. Finishing with the 10k run, the course heads north along Northwest Boulevard and the Spokane River, ending with a finish in the Coeur d'Alene City Park.
