The 16 Hour Lock-in

The 16 Hour Lock-In is an ultrarunning event held at Carolina Beach State Park near Wilmington, North Carolina. Participants have 16 hours to complete as many 4.5-mile loops as they wish on a relatively flat, groomed trail featuring two hills and varied terrain including dirt, sand, pine straw, and a short road section. The race fosters an inclusive atmosphere with no dropouts allowed, accommodating all paces and goals.

The park gates close at 7 pm, requiring overnight campers to stay inside or arrange pickup. Amenities include a stocked aid station, hot meals, and camping options adjacent to the course. Awards and punk rock-themed swag add to the event’s unique vibe. Visit the organization's website for the most recent information.
