Famous Idaho Potato Marathon

The Famous Idaho Potato Marathon, scheduled for May 16, 2026, in Boise, ID, offers runners an unforgettable experience through Idaho's capital. With distances spanning a full marathon (26.2M), half marathon (13.1M), 10K, 5K, and a 1M fun run, there's a distance for every athlete. Participants can look forward to typical race day conditions with highs around 73°F and lows near 48°F, and only a 7% chance of precipitation, creating ideal running weather.

Renowned for its beauty and ease, the course is delightfully flat and fast, showcasing the tranquil Boise Greenbelt as it winds along the scenic Boise River. Full and Half Marathon courses have previously started at Lucky Peak State Park Sandy Point, leading into town, while all races generally follow the paved Boise Greenbelt Trail, with some sections on roads. The marathon is also a USATF-certified Boston Qualifier course. The event, organized by the Treasure Valley Family YMCA and presented by the Idaho Potato Commission, boasts seamless organization and enthusiastic volunteers at aid stations spaced approximately every two miles.

What truly sets this race apart is its strong tie to local agriculture and community spirit, culminating in the famous Idaho Potato Bar at the finish line, where every finisher is greeted with a hearty baked potato complete with all the fixings. This professionally-organized, family-friendly race is celebrated by runners for its scenic views, festive atmosphere, and the unique "spudtastic" post-race celebration, often featuring photo opportunities with the Idaho potato mascot. The event typically starts and finishes at The Morrison Center, providing a central hub for all the excitement.
