About this race
Tackle the Boise River Greenbelt on a loop course. This is the Treasure Valley's only relay race, now in its second year. New for solo runners is an ultra distance, one of the Northwest's fastest & flattest non-looped courses. Relay teams of two, four, or six/seven collectively tackle the Greenbelt, exchanging a slap bracelet in designated zones. The course closes at 5PM.
