Mum Judy Baker will parade through London wearing a decorated bra to raise £1,000 for a breast cancer charity
Judy, whose husband Richard is general manager of Brighton's De Vere Grand Hotel, will be among 8,000 people setting out on the 26-mile walk at midnight on Saturday.
The annual event, to raise money for Breakthrough Breast Cancer, is in its fifth year. Organisers hope to raise more than £1 million.
Judy and six pals - three from Brighton, two from Eastbourne and one from the north of England - are keen to play their part.
She said: "We decided to take part because breast cancer touches most people's lives."
