Team GB won three golds on Saturday and will be hoping for yet more medal glory on the final day of competition on Sunday. Here, we take a look at Great Britain's competitors ahead of their involvement on day 16 at the Olympic Games.
ATHLETICS: Scott Overall
A good friend and former training partner of Mo Farah, Overall secured his place on the team by virtue of finishing fifth in Berlin last year in his first marathon. Matching Farah's medal-winning exploits will be unlikely but a top-10 marathon finish will be the target.
CYCLING: Liam Killeen
The 30-year-old from Malvern is set to compete in his third Games cross-country mountain bike event at Hadleigh Farm in Essex. Killeen was fifth in Athens in 2004 and seventh in Beijing in 2008, when he was caught up in a crash.
MODERN PENTATHLON: Mhairi Spence
The 26-year-old Scot goes into Sunday's modern pentathlon competition as the world champion and hoping to fence, swim, ride, run and shoot her way to Olympic gold.
BOXING: Fred Evans
Welsh boxer Evans aims to complete his extraordinary journey to Olympic gold with victory over Kazakhstan's Serik Sapiyev in the welterweight final. The 21-year-old has been in irresistible form in the tournament to date but will have his work cut out against an awkward opponent.
