QUIZ: Who's won more Olympic gold medals?

British cycling's power couple Jason Kenny & Laura Trott dominated on Tuesday as they helped Team GB take their medals tally to 50 in Rio.

Kenny equalled Sir Chris Hoy's British record of six Olympic titles having claimed victory in the keirin, after his fiancee Trott had become the most successful female British Olympian in history after completing a dominant win in the omnium.

Kenny had already won the team sprint on Thursday and individual sprint on Sunday and the 28-year-old from Bolton completed the clean sweep of sprint events at this year's Games with another supreme performance in a controversial final.

As for Trott, the 24-year-old from Harlow joins an illustrious list of British Olympians to have won four golds as she moved alongside Sir Ben Ainslie and Sir Matthew Pinsent on that mark.

Kenny and Trott have now won 10 Olympic gold medals between themselves since Beijing 2008, more than some nations in the same time period.
