Track Cycling Worlds: Great Britain look ahead to Colombia

Olympic champions Laura Trott, Jason Kenny and Ed Clancy are among the Great Britain cyclists who will be in action at the World Track Cycling Championships, which begin in Colombia on Wednesday.

Trott, along with teammates Dani King, Joanna Rowsell and Elinor Barker broke the world record as they won the new-look team pursuit at last year's Track Cycling World Cup in Manchester.

Defending world sprint and keirin champion Becky James says she thinks this will be one of the toughest ever World Championships.
