Italian Elia Viviani held off Mark Cavendish to win gold in the men's omnium at the Rio Olympics, while Laura Trott leads the women's event.
Only one gold medal was on offer at the velodrome on Monday and Viviani secured it for his first Games success.
The 27-year-old finished with a total of 207 points, beating Great Britain's Cavendish (194) and Danish 2012 champion Lasse Norman Hansen (192).
South Korean Park Sang-hoon was taken from the velodrome on a stretcher in a neck brace after a crash during the points race.
GB's Trott is in front in the women's omnium, holding an eight-point advantage over Jolien D'Hoore.
Defending champion Trott, who already has a gold in the team pursuit in Rio, top scored in the individual pursuit and elimination race.
Kristina Vogel, fourth in the women's sprint in 2012, is into the quarter-finals, while London champion Anna Meares failed to make it.
Tears flowed for Viviani, bronze medallist in the omnium at the world championships last year, after his win. His time trial (36 points) and flying lap (38) set up his victory.
For the first time at these Games, no records fell in the velodrome. However, Viviani became the first Italian man to win a cycling track gold since 1996.
"I'm happy. Elia was the best guy there. If you take the points I lost in the elimination I would've been right with him," - Cavendish praises his Italian rival after taking silver.
"I want to give myself the opportunity to be removed from this environment. I promised myself some time to comprehend everything, and make a decision. I just wanted to get here and race," - two-time Olympic champion Meares is considering her future after finishing 10th in the women's sprint.
