Without the support of enthusiastic and caring volunteers producing our races would not be possible. Volunteers of all ages and abilities help with setup, check-in, aid stations, course marshaling, timing, and post-race food.
Volunteering is a fun, novel way to experience races, play in the outdoors, and spend time with friendly people. All volunteers receive a free race T-shirt, free food, and the ability to earn credit toward a future Inside Trail Racing event, commensurate to the amount of time worked. Five hours of assisting an event results in a free race credit or Inside Trail merchandise.
