Laura Trott is nicely poised in first place at the halfway point of the women's omnium at Rio 2016. The dominant Team GB cyclist, who helped break two team pursuit world records alongside Katie Archibald, Elinor Barker and Jo Rowsell-Shand en route to becoming the first British female athlete to win three gold medals on Saturday, won the six-discipline event in London four years ago and began the defence of her title with a second-place finish behind Tatsiana Sharakova in the 10km scratch race.

The 24-year-old rider later took the lead by winning the 3km individual pursuit in an excellent time of 3:25.054 and closed day one with an eight-point buffer over Jolien D'Hoore of Belgium and the USA's Sarah Hammer by winning the elimination race in typically commanding fashion. The omnium concludes tomorrow (16 August) with a 500m time trial followed by a flying lap and a 20km points race.

Also set to be resolved on the final day of racing inside the Olympic Velodrome is the women's individual sprint. Keirin silver medallist Becky James and Katy Marchant are both through to the quarter-finals after victories over Virginie Cueff and Miriam Welte. They now face Zhong Tianshi and Simona Krupeckaite respectively for a place in the last four.

Jason Kenny will also bid for his third gold medal of the Games and a sixth overall in the men's keirin. He pulled level with Sirs Bradley Wiggins and Steve Redgrave with success in the team and individual sprints and another victory would see him equal another knight of the realm in Chris Hoy, to whom he lost at Beijing 2008.
