A team of sporting north Norfolk women braved today's rain to complete an al-fresco treadmill marathon ahead of taking part in a 26-mile charity walk through London.

The team of fundraising friends from North Walsham and Mundesley also showed off their specially decorated bras, which they will be wearing when they step out for the annual Moon Walk next month.

The twilight event, which attracts thousands of competitors, raises money for breast cancer causes and is now in its 15th year.

The ladies, many of whom are members of Rossis gym in North Walsham, set up a stand in Mundesley's shoppers car park and began walking at 8.30am, and hoped to complete their joint marathon by 2.30pm. They also held a raffle and sold home made cupcakes to passing visitors and supporters in a bid to boost their fundraising total.

Lisa Payne, 36, was among a smaller group who completed the walk last year and will be lacing up her trainers again for 2012's event - and hope the 18-strong team will complete the course in six hours.

She said: 'It's an amazing atmosphere, you just keep going through the night and the supporters on the way and volunteers from the Moon Walk are fantastic. And there's so many different bras, you spend all your time looking at everyone's bras.'

Organisers send walkers a plain bra ahead of the event and competitors are then encouraged to let loose and 'administer fluff in any way they fancy'. And with the theme of 'rocking around the world' many of the north Norfolk ladies picked a patriotic pattern and have adorned their underwear with Union Jack flags.
