Terrible Twelve

The Terrible Twelve is a 12-hour self-supported trail running event held at the Warhill Nature Trail in Williamsburg, Virginia. Participants run or walk as many 3.7-mile loops as possible on a crushed gravel course featuring rolling hills and scenic views, though personal lighting is required for night running. The race starts at 7 PM and ends at 7 AM, with a unique format requiring runners to volunteer for one hour during the event to support others.

Amenities include water, Tailwind nutrition, a grill, indoor restrooms, and ample space for tents. The event fosters camaraderie despite challenging conditions and is ideal training for ultra-distance races. Visit the organization's website for the most recent information.
