12 Hour - Adventure Trail Run
The 12-HR ATR will be held in Prince William Forest Park (PWFP), www.nps.gov/prwi just outside of Triangle, VA in Prince William County. The Park is 17,000+ acres and has over 40 miles of trails. The course will be on a DIFFERENT set of trails than our 24-Hour ATR.
The course boasts a 6.5 mile looped figure eight (8). It is designed to challenge the novice and experienced trail runners alike. It will be 100% trails, some single track, and some fire road. The approximate elevation gain/loss is 650 feet per loop.
The terrain will have undulating hills with some nice ascents and descents to keep trail runners on their game and keep them honest. There will be rocks; there will be roots, dirt, and mud if it rains. There will be two aid stations. The primary aid station will be the Start/Finish. It will have a plentiful array of sustenance (food) to cover everyone through out the event. The second aid station will ONLY have H2O. The 12-HR is concluded with the awards ceremony and Post-Race Meal for participants and crews. Our local community supporters include REI and The Running Store!
