Rio 2016 - 100 days to go
Olympic Games begin 5 August
UK Sport has predicted Britain could win as many as 79 medals in Rio, where the Games begin on 5 August.
Mo Farah will be attempting to win another Olympic double after taking 10,000m and 5,000m gold in London, while Jessica Ennis-Hill will defend her heptathlon crown.
Performance analysts Gracenote have predicted both to win medals again in Rio - and say while Team GB will fall "somewhat short" of UK Sport's target, "it is looking like having its best ever Olympic Games when not hosting", with 65 medals.
