Another thought is fun runs ( of course you'd have to find someone who could actually run!)
Or we could do a fun wobble and roll instead!
Find us a nice short paved circuit in Hyde Park or somewhere, see if we can borrow a few spare wheelchairs from nearby organisations for folks who have a bit too much of a wobble on? Hmm ... Ever heard of the 'Karma Army'? I'll bet they could find us some able bodied, enthusiastic volunteers to help us out! We'd probably need the support of St. Johns! You're a member aren't you Retro? There'd be a cost to that though I suppose? Ooh, and a nice refreshments station so we don't have to carry loads of drinks with us ... Betcha we could blag the loan of a portaloo from some company too!
And ask the London Marathon organisers if we can borrow some of their funky silver blankets just in case! Maybe we could raise enough to cover the start up costs for some HMSA merchandise?
There's an HMS Olympics thread somewhere - maybe we should use some of those ideas too!
I like your thinking Weiza! I really should post some of my own ideas, but it is time for me to get off this site and make some food!
