Great Britain added three more medals to their Rio 2016 total on day 10 as Charlotte Dujardin became the first British woman to retain an individual Olympic title after winning gold in the dressage.
Sophie Hitchon won Team GB's first hammer medal since 1924, while Mark Cavendish claimed his first ever Olympic medal in the omnium.
Historic gold for Dujardin and Valegro
Charlotte Dujardin rode Valegro to their second consecutive individual dressage gold medal, repeating their feat of four years ago with a score 93.857%, to become the first the first British woman to retain an individual Olympic title.
The 31-year-old, who won silver earlier in Rio as part of Britain's dressage team, set an Olympic record Grand Prix freestyle to successfully defend her title ahead of Isabell Werth and Kristina Broring-Sprehe, who won silver and bronze for Germany respectively.
In winning her third Olympic gold, having also triumphed in the team event at London 2012, Dujardin joins Laura Trott as the only female British Olympians with three gold medals.
Third time lucky for Cavendish
It was a case of third time lucky for Mark Cavendish as he claimed his first Olympic medal, winning silver in the men's omnium. An Olympic medal was one of the few honours that have eluded the 'Manx Missile' in his illustrious career, after missing out on a medal in the madison in Beijing in 2008 and on the road in London in 2012.
However, his wait for an Olympic medal was over after he held off the charge of Denmark's Lasse Norman Hansen in a dramatic points race - the last of the six events. Italy's Elia Viviani took gold with a final points tally of 207, with Cavendish finishing with 194 and Hansen 192.
Elsewhere on the track, Laura Trott's dominance of the women's omnium continues as the defending champion leads at the halfway stage after wins in the individual pursuit and her favoured elimination race.
Hitchon wins bronze in hammer
Sophie Hitchon became the first British female in history to win an Olympic hammer throw medal after throwing a personal best distance of 74.54m, which was enough for her to win silver.
Hitchon went into medal contention with an effort of 73.29m from her second attempt, but she knocked out of the medals in the fourth round. However, Hitchon was not to be denied her moment in history and secured a historic bronze medal with a British record distance of 74.54m.
More medals could be on their way...
