There are too many parts that are runner-unfriendly due to the size and type of gravel being used. I have been coming away with very tender feet after long runs through there. I was ready to never go there again. But I was introduced to the power line and mountain-bike trails on the Wakefield side and had observed similar trails on the Accotink side and decided to go for it again. After trying the mountain bike trails once before, I kept getting redirected to the main trail, apparently by the choices I made.
Persistence pays dividends.
Having already explored the Wakefield side, I decided to drive to the Accotink side. The trails are on either side of Braddock Road. At the point where the trail becomes a road, there are power line trails to either side. I chose the right trail, and had to cross three streams to end, eventually, onto Braddock Road. Out and back only took about twelve minutes.
