A bicyclist who died at the 7-Eleven Velodrome track at Memorial Park on Tuesday night was identified by the El Paso County Coroner as 51-year-old Victor Williams.

The United States Olympic Committee confirmed Wednesday that Williams was participating in a training race as part of a Tuesday night race series when he was thrown from his bike.

Firefighters, ambulances crews and track workers tried to help Williams. Police say he suffered critical injuries and was pronounced dead at the scene.

"This is an extraordinarily sad day and our thoughts are with the athlete's family and the entire cycling community during this difficult time," said Patrick Sandusky, USOC chief of communications and public affairs, in an emailed statement.

USA Cycling released a statement announcing Williams' death.

Williams, of Lone Tree, was involved in nearly every aspect of cycling for the past 30 years, including running teams, promoting race series and coaching junior cyclists. Williams also raced nationally and internationally in road, track and cyclo-cross events, the release said, according to The Denver Post.

Williams was racing with about 22 other cyclists — including his teenage daughter, Kirsten — at the time of the crash, according to Mark Tyson, a long-time coach at the velodrome.

The coroner did not release details on where Williams was from.

The 7-Eleven Olympic Training Center Velodrome, as it is known, is the official training site for the U.S. Olympic and Paralympic track cyclists and USA Roller Sports, according to facilities information on the US Olympic Committee website. It is one of two velodromes in Colorado, USA Cycling confirmed Wednesday, and one of 29 in the country. The track was built in 1983 and is 333.3 meters.
