Rio Olympics: Laura Trott becomes Team GB's most successful female Olympian after winning another omnium gold
Laura Trott is a four-time Olympic champion after winning her second gold of the 2016 Games in Rio.
The 24-year-old from Cheshunt took a commanding 24-point advantage into the points race, which concluded the six-discipline omnium, and rode a masterful race.
Trott, who won team pursuit gold on Saturday, successfully defended the title she won at London 2012 to take her to four career Olympic gold medals, the most for a female British Olympian.
The Briton finished with 230 points, 24 clear of her nearest rival, after enhancing her advantage in the discipline which was once her Achilles heel.
Sarah Hammer of the United States was second on 206 points and Belgium's Jolien d'Hoore third on 199.
Trott won her first world title in the discipline since 2012 in London in March after three successive second places behind Hammer (2013, 2014) and Annette Edmondson of Australia (2015).
She had struggled with the format change which saw greater emphasis placed on the points race, but coach Paul Manning deserves immense credit for her vastly improved race craft.
She won three of the first five disciplines, including the penultimate flying lap to move on to 196 points entering the points race, which took place over 100 laps and featured 10 sprints. D'Hoore and Hammer had 172 and Edmondson 168.
Elia Viviani had a 16-point lead over Mark Cavendish in the corresponding men's omnium, which took place on Monday, and the deficit proved too much for Cavendish to bridge, so the omens were good.
The leading quartet, who had a cushion of nearly 30 points over fifth-placed Laurie Berthon of France, stayed with each other for much of the 25km race.

Trott scored at the first sprint, extending her lead to 25 points, and at the second, behind Hammer and d'Hoore.
Hammer and d'Hoore tried to stretch Trott, but she shut down the moves and scored at the fourth sprint to take her lead to 24 points once again.
Bar any drama, Trott appeared to be cruising to glory. She took a lap alongside Hammer and d'Hoore, who consolidated their podium places as Edmondson missed the move.
And Trott won the fifth sprint - and the sixth - to move 31 points clear.
New Zealand's Lauren Ellis moved into podium contention by taking a lap for a third time, moving from seventh to fourth overall.
With 12 laps to go, d'Hoore and Hammer attacked again. It was their final chance to consolidate their podium places and to try to break Trott.
Trott again reacted, reeling them in, before crossing the line victorious. Once again. She has never been beaten in Olympic competition.
A fourth gold saw Trott move above Charlotte Dujardin in the reckoning after the equestrian rider won her third gold on Monday.
Trott's success took Britain's tally to five gold medals and three silvers from the eight events which had concluded, but Britain were only represented in seven after failing to qualify in the women's team sprint.
