Boise Marathon

Welcome to the Boise Marathon. The Boise Marathon will offer the summer option for our marathon series. June 20th promises to be one of the longest Boise days. Sunrise is at 6:04 a.m. and while Sunset is scheduled for 9:30 p.m., you know that Boise sun can hang in the sky until late into the evening. We can't imagine a more perfect day to run our Summer Marathon. DISCLAIMER: Boise also likes to offer multiple weather seasons throughout a June day. We'll promise the sunrise/sunset time, not sure about what season. Marathon Series: Spring - Boise River Marathon - May 2, 2026 Summer - Boise Marathon - You found it!!!
