  Event Information

  Welcome to the Scenic Challenge!

  The Coeur d'Alene Triathlon, Duathlon and Sprint is one of the most scenic races in the Pacific Northwest. This year marks the 41st year of the race which will be held Saturday, August 9, 2025

  Athletes participating in our traditional Olympic distance (1.5K swim) will board one of the beautiful Coeur d'Alene cruise ships and enter the water out in the bay and swim back to the sandy beach shoreline of one of the city's most iconic parks.

  The "Sprint Distance Triathlon" has become a popular staple of our race and will take off from the city park beach one hour after the Olympic race begins. The Scenic Sprint consists of a 500-meter swim, a 13-mile bike ride, and a 3.1-mile (5K) run. The sprint course will have women and men-specific wave starts to give novice triathletes a sense of confidence and safety.

  The bike courses follows the shoreline on Coeur d'Alene Lake Drive. For Olympic distance triathlon riders and Duathlon riders going the full 40K, the race leads to Mullan Trail Road for a challenging uphill course.

  The run courses travels north along the North Idaho Centennial Trail and the Spokane River. There are two turn-around points along the Centennial Trail: the 5K turn-around is in front of the University of ldaho/LCSC Harbor Center, and the 10K turn-around is on the Centennial Trail under the Seltice Way overpass. The course ends at the finish line in Coeur d'Alene City Park at the Triathlon Village adjacent to Lake Coeur d'Alene and City Beach.

  Please Note: Late registrations may have limited event shirt availability.
