An out-and-back 10km course from parking area D in Prince William Forest Park. TAC certification shown has since expired. Terrain is entirely asphalt, very gently rolling or flat, using the Scenic Drive (aka park loop road) bike path from parking area D to the Oak Ridge road intersection and back. (The start/finish is the same as that used for the Virginia Hotfoot Half-Marathon.) A downloadable PDF including both the map below and the certificate is available here: https://tinyurl.com/ritesofspringcertification.
