From the Washington Running Report Express e-newsletter:
"Two incidents on Virginia's recreational trails on Saturday have raised runners' safety concerns. At approximately 11:17 a.m., a woman was reportedly cut in the upper left side of her torso by a man who jumped out of the brush as she was walking along the Four Mile Run Trail. The man ran away, she suffered superficial injuries but remains hospitalized Monday, according to the Arlington County Police Department, which has not released any information on the assailant. The attack happened between the N. Ohio Street and Patrick Henry Drive overpasses over I-66.
Around 8:30 p.m., a woman was charged with driving while intoxicated and felony hit and run after she drove nearly five miles to Vienna on the W&OD Trail from Reston and hit a bicyclist, who was thrown from the bike onto the trail's shoulder, and nearly hit a handful of other trail users."
