The 16 Hour Lock-in

The 16 Hour Lock-In at Carolina Beach State Park

The 16 Hour Lock-In is an endurance event held at Carolina Beach State Park, organized by Punk Rock Ultras. Participants run a 4.5-mile loop within the park and may repeat the loop as many times as they wish during the 16 hour event period. The course runs through a coastal maritime forest and is described as groomed, wide, and relatively flat, with two hills of about 100 feet of climb per loop. Underfoot surfaces include dirt, sand, pine straw, roots, and a short section of road with a grass alternative.

Support at the Start/Finish area includes sheltered drop bag space, bathrooms, and an aid station offering water, Tailwind, and a variety of salty, sweet, and savory snacks. Two hot meals are provided during the event and organizers try to supply vegan and gluten free options when notified. The event is cup free so participants must bring a refillable hydration vessel. A headlamp or similar light is required for night running.

Camping options are available. Thirty 10 by 10 group campsite spots are offered near the race area with primitive amenities. The park also has a family campground a short walk or drive from the course. Awards include patches for recognized distances and a buckle for 100 mile finishers. Volunteer roles are available with benefits such as a race shirt and priority registration. Visit the organization's website for the most recent information.
