Hogan, 59, was pronounced dead at Winchester Medical Center at 11:24 p.m. Wednesday, according to Jefferson County Sheriff’s Deputy A.S. Hockman. Hogan, who was among hundreds of cyclists participating in the 2012 Bike Virginia Tour, was wearing a helmet when he struck his head in the crash at the Duffields railroad crossing about 10:30 a.m. Wednesday, the sheriff’s office said. Hogan was in cardiac arrest as he was transported to Jefferson Memorial Hospital in Ranson, W.Va., and then was flown to Winchester, the sheriff’s office said. Deputies said a tire blew on the bike as Hogan was riding toward Shepherdstown. Wednesday was the last day of the 25th year of the cycling event, which began June 22 in Clarke County, Va., and took riders through Washington County, Md., and Berkeley and Jefferson counties in West Virginia.
