Boise Marathon

Lace up for an unforgettable journey through Idaho's capital at the Boise Marathon on June 20, 2026! Featuring a full marathon (26.2M), half marathon (13.1M), 10K (6.2M), and 5K (3.1M), this event offers a distance for every runner. The course is renowned for being mostly flat to gently rolling, primarily on paved roads, making it a fantastic opportunity for personal bests and even a Boston Marathon qualifying time. You'll begin and end your race in vibrant downtown Boise, tracing the picturesque Boise River Greenbelt, a scenic pathway celebrated for its lush greenery and serene river views. Runners will soak in the sights of Boise State University, the State Capitol building, and charming local neighborhoods like Harrison Blvd. and Hyde Park.

Prepare for typical race day conditions with highs around 84°F and lows around 56°F, and only a 2% chance of precipitation, creating a comfortable environment for your run. While the elevation is around 2700 feet and some sections of the longer courses may have minimal shade, plentiful aid stations strategically placed approximately every two miles will keep you hydrated and fueled with water, sports drink, and GU gels. Runner reviews consistently highlight the beautiful scenery and the welcoming atmosphere. With comprehensive support, including portable toilets near every aid station and course monitors equipped for first aid, the Boise Marathon promises a well-organized and enjoyable experience for all participants.
