OSS/CIA 50 Mile Night Run

The OSS/CIA 50 Mile Night Run is a unique trail running event held in Prince William Forest Park, Virginia, which has historical significance as the training ground for OSS spies during World War II. Participants will tackle a challenging 50-mile course consisting of a 25+ mile loop run twice, primarily on single track trails. The event features fully-stocked aid stations and allows pacers starting from the second loop.

Crews are restricted to the start/finish area for safety reasons. This event not only tests endurance but also pays homage to the park's rich history in intelligence training. Visit the organization's website for the most recent information.
