Another aspect to London is of course the 2012 Olympic Games, so put the two together and you get the TfL Underground Olympic Legend Map.
Appropriately water sports have got the blue coloured Piccadilly line, and you can see legends like Steve Redgrave (Knightsbridge) and Russell Coutts (Russell Square - a nice touch that).
And in the centre at Covent Garden is Ben Ainslie.
