Cycling: First world record broken at the Olympic Velodrome Great Britain's Victoria Pendleton and Jess Varnish advanced to tonight's final of the women's team sprint as world champions Australia qualified fastest with the first world record at London's Olympic Velodrome. Australia's Kaarle McCulloch and Anna Meares - the clear favourites for Olympic gold in the event - combined to better their own mark from the 2010 Track Cycling World Championships, clocking 32.828 seconds on in the two-lap event on day two of the Track World Cup. Varnish and Pendleton showed their continual improvement by becoming the second team to dip below 33 seconds, clocking a British record of 32.966secs to progress to tonight's gold medal ride-off. The battle for third will be contested by China and France. Ben Swift comfortably negotiated qualifying in the men's omnium, finishing fourth in his heat. Meanwhile, Dani King was set to replace Wendy Houvenaghel in the British squad for this evening's women's team pursuit final. Women's endurance coach Paul Manning suggested a change was likely after Britain qualified second fastest behind Canada and King, world champion last March, was withdrawn from her scheduled ride in the non-Olympic scratch race. Instead she was poised to join Laura Trott and Joanna Rowsell in the three-woman, three-kilometre event against Canada.
