Jake Humphrey introduces action from the second day of the World Cup meeting at the Olympic Velodrome in London.

This final leg of the series also doubles as the test event for the summer's games and many of the world's top cyclists will use the opportunity to familiarise themselves with the track and facilities.

Great Britain's track cyclists won seven of the ten gold medals on offer at the last Olympics, and reigning Olympic champions Sir Chris Hoy and Victoria Pendleton are expected to be among those in action this weekend, alongside rising stars such as sprinter Jess Varnish.
