Rio de Janeiro, Aug 17 (IANS): British track cyclists continued their strong performance at the Rio Olympics, increasing their gold collection to six after winning women's omnium and men's keirin.

Laura Trott became the first female athlete representing Britain to win a fourth Olympic gold medal after wrapping up women's omnium title on Tuesday. She also became the first woman to collect a fourth Olympic gold medal in track cycling, surpassing Felicia Ballanger from France, reports Xinhua.

"I am so proud at what I achieved," said Trott.

"We believed in ourselves, and in our team. It just started to snowball."

US athlete Sarah Hammer and Jolien D'Hoore got the silver and bronze respectively.

Trott's fiancé Jason Kenny won men's keirin which was restarted twice. Matthijs Buchli from the Netherland took home the silver. Malaysian Azizulhasni Awang ended up with a bronze.

"We never thought we'd get anywhere near it here, but we've turned up and done the business again," said Kenny about Britain's progress in the recent three Olympics.

Kristina Vogel from Germany beat British talent Rebecca James to clinch victory in women's sprint. James won the silver and Elis Ligtlee from the Netherland bagged the bronze medal.

Vogel became the second woman representing Germany to win an individual gold medal in cycling track. In 1992, Petra Rossner won gold in the women's 3km individual pursuit.
