Track World Cup: Wendy Houvenaghel wins individual pursuit silver
Northern Ireland's Wendy Houvenaghel has added a World Cup silver medal in the women's individual pursuit to her gold from the team event in Colombia.
The Olympic silver medallist clocked a time of three minutes and 33.698 seconds as gold went to New Zealander Alison Shanks who finished in 3:28.994.
Trott is currently in fifth place at the halfway point in the omnium.
What is the omnium?
- Six races - the flying lap, points race, elimination, individual pursuit, scratch race and time trial.
- Points awarded for each discipline - one point for the winner, two points for second, and so on.
- The gold medal is awarded to the rider with the lowest points total after the six events.
The women's pursuit team are the only British representation in Cali, Colombia, which is hosting the second of the four World Cup meetings.
The squad made the perfect start when Paralympic gold medallist Storey, European champion Trott and Houvenaghel teamed up to comfortably beat New Zealand.
Houvenaghel, 37, won Olympic silver in Beijing behind team-mate Rebecca Romero , but the individual pursuit has since been withdrawn from the London 2012 programme.
