POWER-WALKING mum Briony Emery is not letting a few blisters stop her training for a charity slog round London.

She’s training for the 2009 Playtex Moonwalk, a night-time power walk over 26 miles in the capital on Saturday in aid of breast cancer charity Walk the Walk.

The challenge requires competitors to wear a decorated bra on the walk.

Briony, of Monmouth Road, Dorchester, admitted the training is taking its toll as blisters start to emerge – but she’s determined to complete the task.

“I’ve been wanting to do it for years but it’s always oversubscribed,” said Briony, 34, who said some of her friends had been affected with breast cancer.

She added: “I started my training programme in January and hope to complete the walk in five to six hours if I can maintain my current training pace of just over 12 minutes a mile.

“I’m upping the miles each week and I’m getting blisters. But I’m not going to let them stop me.

“My next big walk will be from Upwey to Portland and back.”

Briony, who is married to Dan and has two children, Otilie, four, and Casper, two, works as a teacher at the Compass Centre in Weymouth.

She will be one of 15,000 people – male and female – taking part in the Moonwalk, which starts and finishes at Hyde Park.

The charity Walk the Walk was formed 12 years ago when a group of women power-walked the New York City Marathon in their bras to raise money and awareness for breast cancer causes. It has grown into a thriving multi-million pound charity raising, to date, in excess of £48million.

Briony said: “I have set myself a fundraising target of £500 and have set up a page on the Just Giving website.

“I organised a pudding party at home recently including a raffle with prizes donated by local businesses and raised £225 so that was great.

“I’m really looking forward to doing the Moonwalk now.”
