Welcome to the Boise Marathon. The Boise Marathon will offer the summer option for our marathon series. June 21st promises to be one of the longest Boise days. Sunrise is at 6.04 a.m. and while Sunset is scheduled 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.

COURSES

One of the most scenic courses in the country located in beautiful Boise, Idaho.

GREAT SWAG

We'll follow our usual recipe of race production to include our coveted race shirt (we're thinking of something other than the t-shirt hoodie for this race), 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. (www.solekids.org)
