WALNUT CREEK -- A 30-year-old woman crashed her bike Saturday on Mount Diablo and had to be flown to a hospital for treatment, a fire official said.
The woman, who has not been identified, most likely lost control of her bike around 10:42 a.m. while she was riding on Northgate Road roughly a quarter mile from the junction of Southgate and Northgate roads, said Battalion Chief Derek Krause of the San Ramon Valley Fire District. She veered off the road and down a 15-foot embankment.
The woman, who was in and out of consciousness while she was being treated at the scene, may have suffered a broken clavicle and a concussion, Krause said. She was, however, wearing a helmet.
Northgate Road was closed for about 10 minutes while the woman was loaded into a helicopter. She was flown to John Muir Medical Center, and her condition was not available Saturday afternoon.
According to Krause, the woman was not even aware how she got to Mount Diablo and had no recollection of the crash.
"Something like that could be temporary, or it could be evidence of something more serious," he said. "However, we do not diagnose in the field."
Fire officials initially said that the woman had been participating in the Fast Freddie Gran Fondo cycling event, but an event spokesman later said park rangers had told him that the woman was on a recreational ride unaffiliated with the event.
