Coeur d’Alene Marathon

The CDA Marathon takes place each May in Coeur d’Alene, Idaho, with race options including the Marathon, Half Marathon, 10K, 5K, and Kids Fun Run. Starting and finishing in McEuen Park, the marathon course is USATF-certified and a Boston Marathon qualifier, making it a solid choice for both competitive runners and those taking on the distance for the first time. The route passes through the city and along the shoreline of Lake Coeur d’Alene, combining community streets with open waterfront views. Race organization is supported by Negative Split, with early packet pickup, on-course aid stations, and staggered start times to keep things smooth on race day. Proceeds benefit the North Idaho Centennial Trail Foundation, which helps maintain and expand local trails.
