The Experience
The Boise Marathon, held on the longest summer day, offers a scenic journey through Idaho's capital. Runners can expect a course that winds through picturesque canyons, lush trees, charming riverside neighborhoods, and some of the country's most beautiful parks.
This USATF-certified event is designed for speed, with minimal elevation change and a net drop that favors fast times. While the weather in Boise in June can be variable, the long daylight hours provide ample opportunity to complete the race, with sunrise at 6:04 a.m. and sunset well past 9:30 p.m.
Participants receive a coveted race shirt, quality swag, and post-race refreshments. All finishers are awarded a medal, making it a rewarding experience for the ~650 runners who typically participate, drawing athletes from around 31 states.
Race-provided description
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.

Great Swag: We'll follow our usual recipe of race production to include our coveted race shirt, sweet swag, and finisher food/drink. ALL participants will get a finisher's medal. Please note that registrants registering within 2 weeks of race date may not be guaranteed a shirt. (We'll do the best we can. We're cutting off registrations once we think we can no longer get you a shirt or a medal. Medals are easy... but we don't know what shirt size folks are until they register so there's no way to know. Thanks to all who register early!!!) Another race put on by team SoleKIDs.
