11 May - Will the weather be kind to those taking part in the London MoonWalk?
The Moonwalk is the brainchild of Nina Barough. In 1996 Nina and friends walked the New York marathon in highly decorated bras to increase awareness of breast cancer.
Now a registered charity under the name Walk the Walk, the MoonWalk is an annual event in London raising millions to increase awareness of breast cancer and to aid further research into the disease. For further information about the event visit the official MoonWalk London website.
