Great Britain's medal flurry at the 2016 Olympic Games in Rio de Janeiro continued on day six as Team GB won four more medals, including gold in the men's team sprint.
The trio of Philip Hindes, Jason Kenny and Callum Skinner clocked a new Olympic record to claim the first track cycling gold medal of Rio 2016, while there were silver medals for Britain in rowing, canoe slalom and rugby sevens.
Team sprint gold on dominant opening night on the track
With an unprecedented medal haul at the last two Olympic Games, the Great Britain cycling team have set their personal bar so high it is almost unthinkable that they could sustain the same level of success in Rio. However, it was a perfect start for Team GB as they won gold in the men's team sprint on a dominant opening night on the track.
Hindes, Kenny and Skinner clocked a new Olympic record to beat New Zealand in a hotly-contested final to land Britain's fourth gold medal of the Rio Olympic Games so far and win a third consecutive Olympic team sprint title.
Earlier on the opening night in the velodrome, Britain's women and men both qualified fastest in the team pursuit ahead of their finals later this week, with the women claiming a world record in the process.
Grainger makes history with fifth medal
Katherine Grainger made history as she and Vicky Thornley claimed a dramatic silver medal in the women's double sculls final, just being edged out by Poland in a thrilling finish. The Polish crew proved stronger in the final 500m to claim gold ahead of the British pair.
The silver medal was a historic moment for Grainger as it takes her Olympic collection to four silver and a gold medal, the haul of five Olympic medals equalling the most won by a British woman, matching Kathleen Godfree's five tennis medals from the 1920 and 1924 Olympic Games.
Grainger is also the first British female to win a medal at five consecutive Games, while it was the first Olympic medal for Thornley having competed as part of the Team GB eight at London 2012.
Silver medals in canoe slalom and rugby sevens
David Florence and Richard Hounslow replicated their C2 silver medal winning performance from four years ago at London 2012 to claim a silver medal in the canoe slalom C2 event. The Slovakian pair of Peter and Ladislav Skantar finished just 0.43 second ahead of the Brits to win gold. Hounslow becomes a double Olympic medallist following his silver in London, while Florence won silver at his third consecutive Olympics.
Great Britain's rugby sevens team defied expectations as they won a silver medal as the first rugby seven medals were handed out at an Olympic Games. A 7-5 victory over South Africa in the semi-final guaranteed Team GB a medal, and, despite a heavy 43-7 defeat in the final to Fiji, they took Britain's medal tally at Rio 2016 to 16.
Chloe Tutton narrowly missed out on a medal on her Olympic debut, finishing an impressive fourth in the 200m breaststroke. The 20-year-old has never competed at a World Championships and only made her European debut in London earlier this year, but she showed that she is one of the sport's most promising talents by finishing just 0.06 seconds behind third-place Shi Jinglin of China in a personal best time.
Elsewhere, Justin Rose made golfing history as he became the first man to hit a hole-in-one at an Olympic Games. The British golfer is in contention after the first of four rounds on four-under par, four shots behind Australian leader Marcus Fraser, while Danny Willett is level par.
Charlotte Dujardin is in a strong position to defend her Olympic dressage title, currently in first place in the individual competition following the Grand Prix stage, with Team GB in silver medal position in the team rankings. Meanwhile, Team GB's women's hockey team continued their unbeaten start to the Rio 2016 tournament with a 2-0 win over Japan.
In sailing, Giles Scott remains on course for the Olympic gold medal after a strong recovery from a poor start saw him retain the top spot in the men's Finn class. Elsewhere, there was a good performance from Hannah Mills and Saskia Clark in the women's 470 as a first placed finish in the day's first race and a sixth in the second left them third overall. In the RS:Z classification, Nick Dempsey finished fifth and eighth to retain silver medal position in the overall standings.
