A 34-year-old Nebraska woman has died after she was hit on a bicycle while taking part in the Ironman Boulder race.
The Colorado State Patrol says Michelle Walters of McCook, Nebraska, was hit by a vehicle while riding on a major highway north of Boulder on Sunday.
Ironman event coordinators issued a statement confirming the woman's death. "We are deeply saddened to confirm the death of one of our athletes at Ironman Boulder," organizers said.
The driver and details of the accident have not been released. Alcohol and speed are not believed to be factors in the crash.
Participants began with a 2.4-mile, one-loop swim in Boulder Reservoir. Athletes then continued on a challenging 112-mile, multiloop bike course, followed by a 26.2-mile running course.
