In California’s San Bernardino Mountains, the 100-mile contest in the annual Tour de Big Bear race was disrupted
when a fierce storm dumped rain on bicyclists on 8,400-foot-high Onyx Peak, says this article on yahoo.com.
The storm left 40 bicycle racers with mild to moderate hypothermia who were taken back to the starting line, county fire spokesman Eric Sherwin said.
“Some were shivering, some were suffering from cramps” but none needed to be hospitalized, he said.
Unusual to have such cold weather during the race
Although summer “pop-up” thunderstorms aren’t rare, it was unusual to have such cold weather during the race, Sherwin said.
“Dressed in cycling clothes, 60 degrees and wet is cold, especially when you’ve got done sweating climbing up a mountain pass,” said race event director Craig Smith.
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature,” according to the Mayo Clinic.
