Boise Greenbelt Relays & 50 Mile Ultra
The event on April 24, 2027, follows the Boise River Greenbelt and is based at Ann Morrison Park in Boise, Idaho. The relay course is a 45 mile loop that starts and finishes at Ann Morrison Park and passes through Garden City, Eagle, and Southeast Boise. A solo option covers 50 miles by following the same first 45 miles and then adding a 5 mile loop.
Distances offered:
- 50 Miles solo ultra (first 45 miles plus an added 5 mile loop)

Relay teams compete in divisions for two, four, six, or seven runners; co-ed teams are permitted and compete in the same division. The course is divided into seven legs of roughly 5-8 miles with six exchange zones. Teams hand off a slap bracelet inside each exchange zone. Every exchange zone provides bathrooms, parking, and an aid station. Runners on a team may run multiple legs and may run consecutive legs if the team chooses.
