Former world champion Mariana Pajon won the women's BMX competition, giving Colombia its first gold at the London Olympics last Friday.
Pajon, her country's flagbearer at the opening ceremony, led from the start on the challenging course and crossed the line in 37.706 seconds after a flawless run.
With David Beckham watching from the stands, Pajon hit form at the right time after being hampered by a shoulder injury earlier this season.
''I've been trying to win this my whole life. I just wanted go out of the gate and win it. It's unbelievable,'' she said.
Seconds after crossing the line, Pajon blew kisses to the capacity crowd as members of the Colombian team started to celebrate. She then was cheered by a couple dozen Colombian fans packed into a small section of the stands.
Pajon credited her win on the dangerous and technical course to the quick start coming out of the first corner ahead of her rivals. Pajon had posted three consecutive wins in the semifinals earlier Friday.
''I have tried so hard for it, and I just did it,'' she said. ''I felt really strong, I had really good gates and that's it. I really had fun on it. ... I have to wake up tomorrow and realize what I have just won.''
Sarah Walker of New Zealand claimed silver and Laura Smulders of the Netherlands took bronze.
Home favorite Shanaze Reade of Britain, who crashed out of the final in Beijing four years ago, was never in contention and ended sixth.
