Ilkley women are hoping for good weather in May when they will be tackling a midnight marathon dressed in only their shorts and bras.
Sophie van Berckel, 36, and Juliet Muirhead, 33, pictured, will be flashing their underwear when they take part in Walk the Walk in London this spring.
The women are already in training for the walking race, sponsored by bra manufacturer Playtex, which will follow the route of the London marathon.
All the sponsorship money the pair raise will go to the Breakthrough Breast Cancer Research charity.
Anyone wanting to sponsor them should contact Mrs van Berckel on (01943) 609402.
