Ellen van Dijk of the Netherlands dominated the women's time trial to win her second gold medal at this year's road cycling world championships on Tuesday.
The time trial specialist, who was the pre-race favorite, posted a time of 27 minutes, 48.18 seconds, beating Linda Villumsen of New Zealand by 24.10 seconds.
Carmen Small of the United States was third, 28.74 seconds behind Van Dijk. Both were part of the American squad Specialized-Lululemon which successfully defended its team time trial on the opening day on Sunday.
The powerful Van Dijk was one of the last down the ramp and the 26-year-old led from start to finish along the 21.8 kilometer (13.5-mile) course.
It was her first individual world road cycling medal, while Villumsen made it onto the podium for the fifth consecutive year, following three bronze medals and a silver.
Small, who considered retirement last season, edged out compatriot Evelyn Stevens by just four hundredths of a second for her first individual medal.
Defending champion Judith Arndt retired last season. Earlier, Igor Decraene of Belgium won the junior time trial, beating favorite Mathias Krigbaum of Denmark.
The 17-year-old Decraene won in 26 minutes, 56.83 seconds over the flat, 21.8-kilometer (13.5-mile) course, 8.66 seconds faster than Krigbaum.
Zeke Mostov of the United States was third, 20.97 seconds slower than Decraene.
Decraene, who is the Belgium national champion, finished second in the discipline in the European championships in July.
