The Moonwalk is a 26.2 mile walk overnight in London in aid of breast cancer - done in a decorated bra (men and women allowed). It is an amazing thing to be part of and the training really gets you fit (I can see more meet-ups just for the training walks).
If anyone is interested in doing it it costs around £50 for entry (payable on applicant in Oct/Nov) which covers cost of a bra t shirt entry pack etc then obviously nearer the time travel to London etc - you have to guarantee sponsor money of £100 each (again maybe some fund raising meet-up activities).
It is the most amazing experience and if you want more information here is the link to register your interest.
I hope we can get a team together it is life changing :-) if you can walk a marathon you can do anything.
