Among the thousands of people running the London Marathon in wacky costumes, or taking strange items with them, will be a Sussex woman knitting a scarf.
Susie Hewer is taking a big ball of wool to the London Marathon
Susie Hewer, from Ewhurst Green, near Robertsbridge, is raising money for the Alzheimer's Research Trust.
Her participation is in memory of her mother Peggy, a dementia sufferer who died two years ago.
Ms Hewer hopes to set a first world record for "longest scarf knitted while running a marathon".
She said: "I'm going to be using large-sized needles and wearing a little apron so I can carry my yarn with me."
Ms Hewer will have to complete the 26-mile marathon with her knitting intact in order to claim a world record on Sunday.
Rebecca Wood, from the Alzheimer's Research Trust, said: "Susie's a great person. It's a novel idea and we were pretty amazed."
