The Coeur d’Alene Triathlon and Duathlon is one of the most scenic races in the Northwest. This year, the race will be held August 11. The 1.5k swim takes place in Lake Coeur d’Alene, a body of water that stretches 30 miles long and up to 3 miles wide. A 40k bike ride goes down Coeur d’Alene Lake Drive, a scenic route that leads to Mullan Trail Road for a challenging uphill course. Finishing with the 10k run, the course takes you north along Northwest Boulevard and the Spokane River, ending with a triumphant finish line in the Coeur d’Alene City Park.
