Rio Olympics 2016: Laura Trott on course for another gold as she leads women’s Omnium after day one

Laura Trott is ideally placed to win her fourth Olympic gold after taking an overnight lead in the women's Omnium in Rio.

Mark Cavendish claimed silver in the men's Omnium to take Britain's tally to four golds and three silvers from six events entered in the velodrome. Britain did not qualify for the seventh, the women's team sprint.

More could follow on Tuesday's final day on the track, with Jason Kenny and Callum Skinner in the men's Keirin, and Becky James and Katy Marchant in the women's sprint quarter-finals.

Trott, world champion and London 2012 gold medallist in the event, is the best prospect of the lot, having won two of the first three disciplines of the Omnium. She was second in the other.

The 24-year-old from Cheshunt was second in the opening scratch race and won the individual pursuit and elimination race - a discipline which has become her trademark - to lead on 118 points.

Belgium's Jolien D'hoore was second on 110pts and Sarah Hammer of the United States third on 108.
