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, indoor restrooms, and space for tents and cooking. The event fosters camaraderie and serves as training for longer ultras. Visit the organization's website for the most recent information.
