LONDON (AP) Bradley Wiggins kissed the track and jokingly compared himself to Barack Obama as he said farewell to the Olympic velodrome in London on Sunday after teaming up with Mark Cavendish to win the madison, the last event of the track world cycling championships.
It was Wiggins' final appearance at the track where an ecstatic home crowd cheered the pair's gold medal as the host finished top of the medals table with five golds among a total of nine.
''It was my last race on this track,'' said Wiggins, who intends to compete in the Rio Olympics. ''Not bad was it?''
Wiggins and Cavendish won the world title back in 2008, since when Wiggins has become the first British winner of the Tour de France and Cavendish a 26-time stage winner. They reunited in the event one last time to take gold eight years on.
''You couldn't have written a better script,'' added Wiggins. ''It was like deja vu from eight years ago. We went on to conquer the world in those eight years, like Barack Obama. We've had a good term in presidency. Come back, full circle and won it again.''
The pair won despite Cavendish coming off his bike, only to get back on.
''We knew we had the legs to do it,'' Wiggins said. ''We just kept on going. We didn't come here to finish fourth.''
Cavendish added: ''Hearing the crowd at the end kept us going. It's incredible, it's untrue.''
It followed Trott's second gold medal of the competition, as she added the omnium title to the scratch race.
Trott headed the first sprint of the points race to take the maximum five points and from there steadily extended her lead to finish with 201 points. Laurie Berthon won a sprint finish with Sarah Hammer to beat the American to silver with one point.
It was Trott's second world omnium title after victory in 2012.
''I am just so happy,'' she said. ''It has taken me four years to get a gold medal back in the omnium and it was just incredible.''
It takes to seven Trott's haul of world titles with Chris Hoy's total of 11 in her sights.
Tianshi Zhong headed a Chinese one-two in the women's individual sprint event.
Zhong won the first two races against teammate Lin Junhong, meaning there was no need for a decider, as she became the first Chinese rider to win a world title in an Olympic event.
Zhong was a member of the team sprint which was relegated from gold to silver on Wednesday, a decision which saw China's head coach Benoit Vetu break his hand after hitting it on a table in anger.
''It was an injustice for me,'' Vetu told The Associated Press. ''But we used that anger for the rest of the worlds. This is just a step to the Olympics.''
Kristina Vogel clinched her fourth consecutive sprint medal with bronze.
Joachim Eilers got his third medal, and second gold, of the championships in the keirin.
It saw Germany finish second in the medal table with three golds in a total of eight with Australia in third.
