Laura Bird from St Ives is running the London Marathon with a fridge on her back.
The seasoned runner is hoping to complete the 26 mile course in less than six hours, which would get her into the Guinness Book of World Records.
She previously ran 10 marathons in 10 days, and the London Marathon in April 2024 will be her 22nd marathon in total.
However, this will be the 30-year-old's first with a kitchen appliance on her back, after a practice run at the Cambridge Half Marathon in March 2024.
Ms Bird hopes her attempt will raise as much money as possible for the children's charity Rays of Sunshine.
