Pictures: Team GB medal hopes for Sochi

Check out Team GB's best medal hopes for the 2014 Winter Olympics in Sochi.
David Murdoch and Eve Muirhead, seen at the front of this picture, are leading the British men's and women's curling teams. The last curling medal for the men's team was in 1924! The women's team have had better luck and won gold in 2002 - can they do it again this year?

Elise Christie is the first British woman to win a World Championship medal in short track, when she finished third in the 1000m in 2013. It's been 20 years since the last Team GB Olympic medal in this event.

Can you spot the difference? On the left is Lizzy Yarnold and on the right is Shelley Ruddman, both medal hopes for the Skeleton. In the last Olympics athlete Amy Williams competed in the skeleton and won the only British gold of the Games.

With the Winter Olympics kicking off, Newsround are looking at some of the top medal hopes for Team GB. Starting us off are freestyle skiers Katie Summerhayes (left) and James Woods (right). Britain has never won a Winter Olympics freestyle medal but with Katie winning a World Cup medal last season and James winning a silver in 2013 in the World Championships, their chances of doing well in Sochi are high.

John Jackson is the pilot for the British men's four-man bobsleigh team. Despite an injury last year he's made a quick recovery and with him piloting the bobsleigh team there are high hopes for a medal here.
