NEW YORK — A bicyclist competing in a race from Logan, Utah, to Jackson Hole, Wyo., crashed on a bridge in Wyoming and fell about 35 feet to his death into the Snake River.
Robert Verhaaren, 42, of Mesa, Ariz., was participating in the annual LoToJa race when he swerved to avoid a pothole and crashed on Highway 89 about 8 miles from the finish line Saturday afternoon, Teton County sheriff’s deputies said.
The 206-mile race also was marred by serious accidents in Idaho and Wyoming that sent two bicyclists to the hospital, and by flat tires experienced by roughly 200 cyclists early on, said race spokesman David Bern.
He said it is the first fatality in the 30-year history of the race, which is billed as the longest one-day bicycle race in the country sanctioned by USA Cycling. This year’s event drew 1,500 competitors from across the nation.
‘‘It was devastating for us to lose a member of our LoToJa family,’’ Bern said. ‘‘Unfortunately, these things go along with bicycle racing. Cycling is not for the risk-averse.’’
Sheriff’s deputies said that when Verhaaren swerved to miss the pothole, he crashed into a guardrail and was catapulted over it into the river.
The victim was an experienced cyclist who had competed in the event at least twice before, organizers said.
Bern said it was the first major accident on the bridge in the race’s history, and organizers would discuss it with Wyoming Department of Transportation officials.
Another cyclist was seriously injured in a crash on the descent from Strawberry Summit in southeastern Idaho, while another was severely injured in a crash near Wyoming’s Alpine Junction about 45 miles from the finish line.
Less than 20 miles into the race, cyclists began experiencing an unusually high number of flat tires. They were blamed on thorny weeds by some and on very small nails by others.
Riders also had to deal with horses on the road and smoke from a Wyoming wildfire during the race.
