If you've entered fun runs in the past and you're looking for a new challenge for a good cause, the Playtex Moonwalk could be right up your street

Fancy doing an event with a difference? The Playtex MoonWalk 2008 will see 15,000 women and men power walk the moonlit streets of London in fantastically decorated bras - yes, that's right, bras, and that includes the men too.

Taking place on 17th May, people from across the country will come together to raise money and awareness for vital breast cancer causes. Although all places for this year's event are sold out, make it a date for your diary next year.

Nina Barough, founder of the charity said: 'It's very exciting to be entering the second decade of the London Playtex MoonWalk. In the past 10 years we have been able to make an important contribution to the lives of many with breast cancer and have encouraged many to change to healthier lifestyle options as a form of preventive health. Now we have ambitious plans for the future, so watch this space!'

Walk the Walk is the grant-making, health charity behind the famous MoonWalk events in London and Edinburgh and the SunWalk's in Bristol and Newcastle. The stirrings of the charity began in 1996 when Nina and 12 other women power walked The New York Marathon in their bras to raise money and awareness for breast cancer research.

It probably would have remained as a one-off thing, but in January 1997, Nina not only discovered that she had breast cancer but that it was an aggressive tumour (which she had most probably had for about three years). Her friends power walked the 1997 London Marathon in support.

With Nina in remission, the Walk the Walk team entered the London Marathon 1998 for the second time but only 25 people received places, leaving many disappointed. So as not to leave them out or to waste their fundraising and training, Nina decided to create a one-off marathon for these girls.

The 25 intrepid walkers, plus friends, set off at midnight and completed their marathon at 7.00am on Sunday morning in Trafalgar Square and The MoonWalk, as we know it, was born.

What started out as a once only fundraising event has blossomed into a thriving charity raising to date in excess of £40 million for vital breast cancer causes.
