About the event

Experience the beauty of Boise like never before! The Boise River Marathon offers runners of all levels a unique course that winds along the stunning Boise River Greenbelt — a flat, fast, and scenic route perfect for setting personal records or enjoying a memorable first race.

Whether you're running the full marathon, half marathon, 10K, or 5K, you'll be surrounded by the natural beauty of Idaho and the support of an energetic, encouraging community. This is more than just a race — it’s a celebration of fitness, fun, and the spirit of Boise.

We believe in Boise, and we proudly highlight and partner with the small businesses that make our city special. From local vendors at the finish line to race-day sponsors and community events, your participation helps support the heartbeat of our town.

Why Run the Boise River Marathon?

🏞️ Gorgeous riverside views
👟 Fast, fast course
🎉 Family-friendly atmosphere
💪 Partnered with local health and fitness organizations
🌟 Custom medals, shirts, and unforgettable memories

Join us for a race you’ll never forget. Run the River. Celebrate the Journey. Support Local.

GREAT SWAG
Classic crew neck sweatshirt, swag, finisher food/drink, and 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!!!)
