London 2012 chairman Sebastian Coe and tw-time Olympic decathlon champion Daley Thompson will be at the launch of the Olympic's national roadshow in the Royal Artillery Barracks.

 

They will be joined by Sport England chief executive Jennie Price and Greenwich Council leader Councillor Chris Roberts.

 

This is the first stop, and launch, for the branded London 2012 double-decker bus in its 10-week tour.

 

There are 27 stops in total covering across Britain, ending at Stoke Mandeville on August 29 to mark five years to go until the London 2012 Paralympic Games.

 

The launch will be held on the final day of the Greenwich Sportathon, which has been running at the site since Monday.
