A swimmer was pulled from the water during the Great Chesapeake Bay Swim and taken to a hospital.
The man was pulled from the water about 11:15 a.m. Sunday near the Bay Bridge, the Capital reports. He was one of more than 600 swimmers attempting to complete a 4.4-mile swim across the bay.
The man was unresponsive when he was pulled from the water, rescuers said. Rescuers performed CPR and rushed the man to shore and to a hospital, Anne Arundel County Fire Department spokesman Lt. Cliff Kooser said.
Numerous swimmers were pulled from the water during the event by volunteers on boats.
Event organizers say between 79 and 97 percent of swimmers have finished the race over the past five years.
