Olympics 2016: Team GB stars tipped for Rio gold – pictures
UK stars target a record haul - and could even scoop an amazing 79 medals in Brazil
Jessica Ennis-Hill - heptathlon: The poster girl of the 2012 Games, Ennis-Hill is hoping to become only the third female athlete in history to defend a title having become a mother. Her performance this season suggest that she is a genuine contender for a second gold.
Sir Bradley Wiggins - cycling: If Team GB triumph in the men's team pursuit, Wiggins will become the country's greatest-ever Olympian, equalling Sir Steve Redgrave's haul of five golds while any medal would see him surpass Sir Chris Hoy's total of seven. Given that the team broke the world record in training, it seems possible.
Helen Glover and Heather Stanning - rowing: The reigning Olympic champions are unbeaten in competition for five years and are also world record-holders and firm favourites for the gold in the coxless pairs. Team GB will also be going for a fifth straight gold in the coxless fours.
Mo Farah - athletics: Already considered by some to be the UK's greatest ever sportsman, Farah can cement his greatness at Rio. Since winning double gold in the 5,000m and 10,000m at London, he has scooped four world championship gold medals and defended his European titles over the same two distances.
Jason Kenny - cycling: With three Olympic golds and a silver already under his belt, Kenny has the opportunity to equal Hoy's haul of six golds. The Bolton-born competitor, who is engaged to fellow cyclist Laura Trott, competes in the sprint, the team sprint and the keirin and could potentially win all of them.
Laura Trott - cycling: She emerged as one of the stars of London 2012, winning team pursuit and omnium gold, and will compete in the same two events at Rio, alongside fellow 2012 gold medal winner Jo Rowsell-Shand in the team pursuit. Gold is a possibility.
Adam Peaty - swimming: The London Aquatics Centre may have looked the part but it was home to bad memories for the British swimming team as they failed to meet their medal target in 2012. Fans hope for better things in Rio and Peaty is clear favourite for gold in the 100m breaststroke. The current world record-holder and world champion will take some beating.
Alistair Brownlee - triathlon: Spurred on as ever by his younger brother Jonathan, Alistair Brownlee hopes to retain the Olympic gold medal he won in London. The brothers from Leeds dominate the sport and five of the six-strong British triathlon team are now based in their home town.
Nicola Adams - boxing: Another Olympic gold-medallist from Leeds, Adams became the first woman to win an Olympic boxing title in London and will be confident of defending her title in Brazil. Since 2012, she has won gold at the Commonwealth Games, European Games and world championships.
Jamie and Andy Murray - tennis: Andy Murray is the reigning Olympic champion and last month won his third Grand Slam title at Wimbledon. He will be one of the favourites for gold in the singles, but he and brother Jamie are huge favourites in the men's doubles. The pair teamed up to good effect in the Davis Cup and Jamie also has a Grand Slam doubles title under his belt from Australia this year.
Jade Jones - taekwondo: She was only a teenager when she claimed a surprise gold at London 2012, but "The Headhunter" will become the hunted in Rio. However, the reigning European champion has a great chance of retaining her title, while Bianca Walkden, undefeated in 2016, could also triumph in the heavier weight division.
Tom Daley - diving: Still only 22, Daley will be competing in his third Olympics and will be looking to improve on the bronze from London. Since finding fame as a 14-year-old at Beijing, he has been forced to grow up in the public eye, but despite his high profile and media presence, he remains a committed diver with a great chance of gold in the 10m individual and synchro events.
Giles Scott - sailing: He lost out to Sir Ben Ainslie in the battle to represent Team GB at the 2012 Games but Scott bounced back to establish himself as the best Finn-class sailor in the world, having triumphed at the past three world championships. He is expected to win gold at Rio.
Claudia Fragapane - gymnastics: The dominant female gymnast in Britain, Fragapane won four golds at the Commonwealth Games in Glasgow two years ago and will spearhead Team GB's campaign for a first ever Olympic gold. Fragapane and the women's team have an outside chance of glory, but Max Whitlock could be the one to watch - he is the pommel horse world champion.
Chris Froome - cycling: In 2012, Wiggins won the Tour de France and then claimed gold in the Olympic time trial. Four years and three Tour de France victories later, Chris Froome is hoping to do something similar in Rio, competing in the time trial and the men's road race just a couple of weeks after securing the yellow jersey in France. It would quite an achievement to win Le Tour, fly halfway around the world and then win two races in the space of five days, but if anyone can do it, its Froome.
