Running 48:00 [4] 8.0 km (6:00 / km)

Sheraton Hotel in Crystal City in Arlington to Mt. Vernon Trail and then north, out and back. Nice day. After I turned back, I used 3 guys ahead of me to pace me for a while. They started out about 25 meters in front of me, and that gradually grew until the last km when I pooped out.
