Britain's Laura Trott won her fourth Olympic gold medal with a masterful ride in the track cycling omnium on Tuesday, leaving her rivals fighting for podium places as she defended her title with ease.

Trott, the first British woman to claim three Olympic golds when leading the team pursuit home last week, held a commanding lead going into the points race, the sixth discipline of the event, and turned it into a procession.

As the 24-year-old ticked off the 100 laps without incident, picking up early sprint points for insurance, the real battle was for silver between American Sarah Hammer and Belgium's Jolien D'Hoore.

Hammer finished runner-up, as she did in London four years ago while D'Hoore had to settle for bronze.

Kristina Vogel bags individual sprint gold

Kristina Vogel of Germany swept past Becky James of Britain to win the gold medal in the individual sprint at the Rio Games. Katy Marchant added a bronze for Britain when she swept Elis Ligtlee of the Netherlands.

The world bronze medalist in the event, Vogel knocked off Marchant in the semifinal round to set up her match with James. She won both races in the best-of-three event from the lead, even losing her saddle as she crossed the finish line to win the gold medal.

Kenny wins keirin gold to take haul to six

Britain's Jason Kenny won the men's track cycling keirin on Tuesday, taking his gold medal haul to six and equalling Chris Hoy's record for the country's most Olympic titles.

In a tense race around Rio's boards, Kenny had too much pace down the final stretch, recovering from a slow start to finish just clear.

Matthijs Buchli of the Netherlands won silver and Malaysia's Azizulhasni Awang took bronze.

The final had to be restarted twice after issues with the positioning of the riders and the electric bike that sets the pace in the early laps.
