Fitness enthusiasts from Winslow are preparing for a gruelling and extremely muddy off-road endurance event on Sunday.
The Swanbourne Endeavour is an assault course challenging competitors to race through fields, woods, haystacks, fire and “some of the finest slippery, sticky, foot-sucking clay in all England” for either 5km or 10km.
A group calling themselves the Winslow Warriors, led by fitness teacher Jane Simons, are gearing up for the challenge.
The team is made of 15 runners from Mrs Simons’ Buckingham and Winslow Zumba classes, with eight competitors down to run 5km, and seven to attempt to get through an exhausting 10km.
Mrs Simons said “We thought it looked like a laugh, but I’m slightly terrified.
“The youngest of us is 27 and the eldest in their mid-50s.
“We’re looking forward to finishing it.”
Also taking part in the 10km course will be Kim Curle, owner of Winslow shop Beautifully Different, and her daughter Emily.
Mrs Curle said: “We’ve been doing a lot of training.
“It’s all about core strength and upper body fitness.
“I can’t wait now.”
Mother and daughter are raising money for Breakthrough Breast Cancer, and have almost doubled their £500 target.
All the money raised by the Swanbourne Endeavour entry fee also goes to charity.
