The best selection I've seen is at the London 2012 shop in Hyde Park and the London 2012 shop online, however neither have the complete range of training gear.

If they did have in try going to the Olympic shop i went the other week and there were loads of t shirts in there

On the olympic website and click on shop! then it will bring up all the clothing available!

Can anyone tell me where I can get the adidas navy blue training top that Chris Hoy, Ryan giggs the shot putters have been wearing, and long sleeve I've looked in obvious places but must be for sale!
