What you missed: Day Fifteen overnight highlights from Rio


Mo Farah won his fourth gold, boxer Nicola Adams her second and sprint canoeist Liam Heath his first as Great Britain surpassed their London 2012 medal tally on the penultimate day of the Rio Olympics.

There were bronze medals for triathlete Vicky Holland, taekwondo fighter Bianca Walkden and the women's 4x400m relay squad.

Third in the relay saw Britain take a 66th podium place of Rio 2016 to surpass the haul of 65 medals from four years ago. Boxer Joe Joyce is guaranteed another medal on Sunday's final day.

Britain are also on course to finish above China in the overall medals table, although diver Tom Daley's premature exit handed China's Chen Aisen gold.

Here's a review of Saturday's action:

Mo Farah completed his long-distance 'double double' by adding the 5,000m gold to the 10,000m he won in Rio last weekend and the two triumphs at London 2012. The 33-year-old Londoner held off the United States' Paul Kipkemoi Chelimo on the final bend to sprint clear and become only the second man after "Flying Finn" Lasse Viren to win both titles at two Games. Andrew Butchart was sixth.

Nicola Adams became the first British boxer to retain an Olympic title in 92 years by outpointing Sarah Ourahmoune of France to claim flyweight gold. The 33-year-old from Leeds emulated Harry Mallin, who won back-to-back gold medals in 1920 and 1924.

Liam Heath powered his way to Olympic gold in the K1 200 metres. The 32-year-old made it third time lucky after winning silver alongside Jon Schofield in the K2 200m, to go with his bronze in the same class from London 2012.

Brazil atoned for their 7-1 humiliation at the World Cup to Germany with a penalty shootout victory as Neymar converted the decisive spot-kick. Neymar, ruled out of 2014´s meeting through injury, kept his cool after a match drawn 1-1 after extra time at the Maracana Stadium to send the host nation into raptures.

South Africa's Caster Semenya, who found herself at the centre of a gender row following her victory at the 2009 World Championships and had to undergo gender testing before being cleared to return to competition, claimed gold in the women's 800m final. Lynsey Sharp, who earlier this summer claimed the 800m had become two different races, finished sixth.

Vicky Holland outsprinted best friend and housemate Non Stanford to win triathlon bronze. USA's Gwen Jorgensen took gold.

Bianca Walkden outpointed Wiam Dislam of Morocco 7-1 to become the third member of the British taekwondo team to win a medal after Jade Jones and Lutalo Muhammad. Mahama Cho missed out, beaten by Brazil's Maicon Siqueira to become the 17th Briton to finish fourth at the Games.

The women's 4x400m relay squad of Eilidh Doyle, Anyika Onuora, Emily Diamond and Christine Ohuruogu dug in to finish third behind the USA and Jamaica and clinch Britain's 66th podium place of the Games.

Tom Daley's bid for Olympic gold in Rio ended after he failed to qualify from the semi-finals of the 10 metres platform event, despite topping the preliminary round rankings the day before. The 22-year-old from Plymouth vowed to continue on to Tokyo.
