London, Aug 7 (IANS/RIA Novosti): Britain's Laura Trott sped to Olympic gold in the women's omnium Tuesday by winning a thrilling 500 metre time trial.
Trott clocked 35.110 seconds, with Sarah Hammer of the US, her nearest challenger, coming in fourth with 35.900.
It was enough to secure gold by one point for the Briton, who had been level with Hammer after the first five disciplines. "I cannot believe this is happening to me," Trott said.
"I was losing my head a little bit between the events because they weren't going the way I wanted them to. I am so happy."
Hammer, meanwhile, spoke of her exhaustion. "I gave it my all. It's physical and mental - it's both of those things. That's what it is."
Annette Edmondson of Australia took the bronze after finishing second in the time trial.
Trott, 20, won team pursuit gold Saturday with Britain.
