Runners must check out with the timing partner to finalise finish results and then collect their finisher prize at the NU Limits Basecamp gazebo. Basecamp is marked on the event GPX map, offers kit storage under two 6 x 3 meter gazebos, and welcomes spectators. NU Limits Ltd does not accept liability for lost kit.
