Laura Trott became the first British woman to win four Olympic gold medals by retaining her omnium title.
The world champion, 24, moves ahead of Charlotte Dujardin, who won her third Olympic gold with victory in the individual dressage.
“I can’t believe it. I didn’t expect that at all,” said a tearful Trott, who matched her team pursuit and omnium victories from London 2012 in Rio.
She scored 230 points to win the title by 24 from American Sarah Hammer.
