Typically the Kids Race volunteer shift is from 8:00 AM - 4:00 PM. Volunteers assist the Kids Race Staff with operational needs including but not limited to providing racer encouragement, distributing finisher medals and finish line sponsorship items, safely matching racers to their parents at the finish line, and course tear down. Course tear down will only occur on the last race day of the event and includes removing course tape, breaking down the finish tent and fences, stacking tables, removing trash and signage, and consolidating obstacles for load-out.
Volunteers receive a free race entry for that event or any Spartan kids race registration at that event or a future event, US Sprint, Super, or Beast, a Spartan Support T-shirt, and a meal. Same day racing is not available to Kids Race volunteers but you may use your free race the day prior or following your volunteer day (Example: Volunteer Saturday and race Sunday or volunteer Sunday and race Saturday).
