London 2012: Team GB Olympic medal hopefuls
Team GB has been set a challenge of a top four finish in the medal table and 48 medals from at least 12 different sports.
The target's been set by UK Sport which gives money to train the country's top atheletes.
Four years ago in Beijing, Britain finished fourth in the table with 47 medals, but it's hoped with a home crowd and a lot more money to spend on getting athletes ready, they should be able to do better this time round.
The spots we're expected to shine in include athletics, cycling, sailing and swimming.
