Jill Douglas presents coverage as the Track Cycling World Championships draw to a close with what should be a thrilling final day's action in Ballerup, Denmark.

Olympic legend Chris Hoy will be desperate to reclaim the men's sprint title he was unable to defend last year after a serious fall at this venue in the World Cup final. Hoy has looked sharp so far this year and has gone below the 10-second barrier in 200m time-trial qualifiers at three meetings in a row.

Another British Olympic gold medallist, Victoria Pendleton, is expected to go for glory in the women's keirin. Interest in this event has grown dramatically since it was confirmed as an Olympic event for 2012 and Pendleton will face stiff competition from China's Guo Shuang, Australia's Anna Meares and Lithuania's Simona Krupeckaite.

The men's omnium will also be introduced as an Olympic event at the London Games so competition is sure to be fierce for this event, which comprises five races of differing lengths.
