Less than a year ago, she nearly died after complications with her gastric band.
But now trades union activist JoAnne Rust has her eyes on another prize, completing the London Marathon next month.
Ms Rust, 47, from Gaywood, says she is inspired to take on her first 26-mile run following her near-death experience.
She said: “Last year I nearly died and now I have got this opportunity that at the time I would never have thought I would be able to do. It is just an amazing chance.”
Ms Rust will be raising money for the children’s charity the NSPCC. So far she has had sponsorship to the value of £800, but she is pledged to raise £2,000 and is confident she can get it and is particularly thankful to the support offered by the Hanover Housing Association.
“Training has been going really well,” she said. “I did a long run on Friday up to 17½ miles and expect to step up to 22 miles.”
She has done one half-marathon before but had never dreamed of doing a full marathon. “I love it ... not only is it really good for your health but I find it really helps to settle your mind and relax as it gives you a good chance to think things through as you are running along.”
To sponsor Jo go to her Just Giving page or text JORS47 £1 to 70070. “I’m asking people to give a quid to help a kid,” she said. “I know it is really tough at the moment, but I feel everyone can give a quid for this.”
