His first record was for the 2K Individual Pursuit, a timed event to see how quickly one can ride two kilometers. His prior record, set at Colorado Springs on July 11, was 2 minutes and 51.420 seconds. He improved that to a new record of 2 minutes and 48.483 seconds.
The second record was set for the 200-meter time trial, a timed event where the rider gradually builds up speed over three laps with the final 200 meters being timed. His prior record, also set at Colorado Springs, was 14.100 seconds. He improved that to a new record of 13.889 seconds.
Turner set his final world record for the Hour Record, where riders are measured on how far they can ride in one hour. Turner covered a distance of 38,494 meters, which beat the last record of 37,066 meters set at a velodrome in Switzerland.
"The people that I dealt with at Aguascalientes were absolutely wonderful," Turner said. "They were supportive of my attempts in every way possible."
He was assisted by his long-time coach, Dan Smith, another Menlo Park resident.
The velodrome in Aguascalientes is at an elevation above sea level of 6,200 feet. It has an indoor 250-meter steeply banked wooden track, Turner said.
