Team GB currently sit third in the Olympic Games medal table with 29 in total after winning golds in track and field, rowing and cycling on Super Saturday, and here we take a look at the top Brits in action on Sunday.
ATHLETICS: Adam Gemili
The teenager is living the dream after winning the world junior title in Barcelona and now lining up alongside world champion Yohan Blake in the semi-finals of the Olympic 100 metres.
BASKETBALL: Kim Butler
Butler's 12 points and six rebounds in the heartbreaking 80-77 overtime loss to France were more than she had managed in the previous three games combined, and a repeat performance could help Britain snare their first win against Brazil.
BOXING: Natasha Jonas
Jonas stars as women's boxing makes its historic debut at the Olympic Games. The Liverpool lightweight faces a tough first-round battle against American Queen Underwood, who she narrowly beat at last year's Olympic test event.
CYCLING: Victoria Pendleton
The 31-year-old from Stotfold was set to begin the three-day sprint competition, which concludes on Tuesday, in her final event before retirement. Pendleton was seeking a successful defence of her Olympic title and golden final hurrah after keirin gold on Friday.
EQUESTRIAN: Ben Maher
Nick Skelton might be the spearhead of Great Britain's showjumping quartet at Greenwich Park, but Maher is another integral part of the team medal bid. An experienced, high-class rider. Maher could also be among the individual medal challengers in his second Olympics.
FENCING: Laurence Halsted
The son of two Olympic fencers, Halsted was omitted from the individual competition after being injured earlier this season and is only reserve for the team foil event, but should get on the piste for his Olympic debut at some point.
GYMNASTICS: Louis Smith
The 23-year-old Beijing bronze medallist will look to win Great Britain's first ever gymnastics Olympic gold when he competes in the pommel horse final. Smith is one of the favourites to be crowned champion after he finished top in qualification with one of the world's most difficult pommel horse routines.
HANDBALL: Kelsi Fairbrother
Great Britain women's handball team bring their maiden Olympic campaign to a close against Croatia hoping to bow out with a win, after four heavy defeats. Winger Fairbrother, who plays for the Esbjerg club in Denmark, will hope to inspire a grand finale.
HOCKEY: James Fair
Goalkeeper Fair can expect a busy day against world number one side Australia in a match which is likely to determine who wins Pool A, and keeping the free-scoring Kookaburras at bay will be crucial to GB's chances.
SAILING: Ben Ainslie
The 35-year-old is on the verge of becoming the greatest Olympic sailor of all time. Should he manage to topple leader Jonas Hogh-Christensen in the Finn medal race, it would see him replace another Dane, Paul Elvstrom, as the most decorated sailor in Games history.
SHOOTING: Ed Ling.
The 29-year-old from Somerset came fourth in the trap at the London 2012 test event earlier this year, agonisingly missing out on a bronze medal after a shoot-off. Can he do better on the biggest stage of all?
SYNCHRONISED SWIMMING: Jenna Randall and Olivia Federici
Randall and Federici begin their campaign, competing in the duet technical routine before their free routine the following day as they aim for a place in Tuesday's final. They were eighth in last year's World Championships and fifth at the 2010 European Championships.
TENNIS: Andy Murray
Four weeks to the day since his Wimbledon final heartbreak, Murray will try to overturn the result and beat Roger Federer to Olympic gold. Federer wants the title to complete a career Golden Slam of tennis' four majors and the Olympic title. Later in the day, Murray and Laura Robson go for gold in the mixed doubles final.
VOLLEYBALL: Lucy Wicks
As the team's setter, Poole-born Lucy Wicks will be essential against a Japan side that Great Britain feel they have the measure of. She will dictate the pace of the game and, if she can find her tall wing spikers, Japan may be in some trouble.
WATER POLO: Fran Leighton
The GB women's water polo captain and centre-forward will look to lead from the front in her side's quarter-final clash against Spain. The team have lost all of their games so far, but a win would take them through to the last four.
