Autumn Run Half Marathon, 10K, 5K, & Kids Fun Run

The Autumn Run is held each year on the third weekend in September, in and around the historic, friendly, and picturesque town of Buena Vista, Colorado. Nestled in the upper Arkansas River Valley at the base of the Collegiate Peaks, the Autumn Run has one of the most beautiful courses in Colorado. ​ Online registration will STAY OPEN to race day! For 2023, we will have Early Bird Registration and Late Registration. While we love to provide our runners with amazing race swag, we also must keep our cost (and yours) down by ensuring that we are not wasteful with our orders. Race swag is not guaranteed if you register within the two week window before the event. Register early to ensure you get the goods!
