2026 PENDING Boise Greenbelt Relays Course
PLEASE NOTE: The 2026 Course is still being finalized, but will be similar to the 2025 race. Even after the course is finalized, it is subject to change due to unplanned construction, flooding, etc. We will always keep you aware of any changes and the course will be clearly marked. While the vast majority of the planned course is on the beautiful Boise River Greenbelt with traffic control, flaggers, course marking, and volunteers used to keep participants safe; no roadway will be entirely closed. Shoulders and sidewalks will be utilized where possible, but signalized crossings must still be adhered to by race participants. Please only cross the street when safe!

There will be Tailwind Hydration Mix, gels, chews and snacks at all Transition Zones. Please only take what you need for the race so that we can ensure our ultrarunners have enough fuel!
