The London 2012 Roadshow started and the Roadshow bus will travel around the UK over the Summer.

Visitors were able to take part in 'taster' activities run by Sport England, including Taekwondo, rowing and weightlifting.

The launch was attracting young people to join in with new sports, and activities at the Greenwich Sportathon.  London 2012 Organising Chair Sebastian Coe and Olympic gold medalist Daley Thompson joined pupils from local primary schools for the event .

The National Lottery 'Dream Statistics' zone allowed young people to enter their key statistics and find out which sport they might be best suited to.

On board the Roadshow bus, visitors saw the new 2012 challenge website, which encourages everyone to join in by setting themselves a challenge to achieve by 2012.

Sebastian Coe said: "Greenwich is a host borough of the 2012 Games and it is fitting that the Roadshow will start its journey here at the Royal Artillery Barracks, which is our venue for shooting.

"London 2012 will be a nationwide Games and the Roadshow is only the first part of our pledge to involve everyone the length and breadth of the UK towards, and including, 2012.

"We want to encourage young people to develop their sporting talents, to achieve something for themselves or to inspire others to unearth their own talents.

"Visiting the London 2012 Roadshow is a great first step to accomplishing this."
