Team GB medal hopes - day 15

Team GB won silver medals in the men's 470 and the women's 470 on Friday, while the women's hockey team and taekwondo fighter Lutalo Muhammad claimed bronze to take our Olympic Games medal total to 57. Here we have a selected look at our competitors ahead of the action on day 15.

ATHLETICS: Mo Farah

Farah helped to ignite the Games with the last of Britain's three gold medals in 45 minutes, triumphing in the 10,000 metres on 'Super Saturday'. And he will hope to bring it to a close in similar fashion seven days on in the 5,000m, the event in which he is already world champion.

BOXING: Luke Campbell

Campbell goes for gold in the men's bantamweight division against old foe John Joe Nevin of Ireland. The pair have split their previous two meetings, with Campbell edging last year's World semi-final on countback, and another close one can be expected.

CYCLING: Annie Last

The 21-year-old from Bakewell, Derbyshire will take to the Hadleigh Farm course for the mountain bike cross-country event as the first British woman to take part since Sydney. Last deferred her place at medical school to concentrate on London 2012.

HOCKEY: Harry Martin

Midfielder Martin has improved with each game at his first Olympics, and the 19-year-old has provided an attacking drive from deep positions which has caused problems for opposition defences. He will be looking to do the same against Australia in the bronze medal match.

MODERN PENTATHLON: Nick Woodbridge

Modern pentathlon is a notoriously unpredictable sport but world number nine Woodbridge won bronze at the Olympic test event last year and will hope to challenge for a medal again.
