Running the half marathon in her heavy navy outfit should not be a burden for Kelly who got into shape after losing eight stone.
The turning point for Kelly, from Romiley, came five years ago when she advised a patient at the hospital where she was a nurse that she might want to lose weight.
It persuaded Kelly to change to a much healthier lifestyle, dropping her dress size from 24 to a trim 12 in the process.
Kelly said: “It felt embarrassing to tell someone to lose weight when I was that big. I was so glad I changed my own lifestyle.”
Kelly fulfilled a dream when she joined St Ann’s in January. “I was a student nurse here in 2004 and loved it. It’s an amazing place and I feel proud to be back as a sister.
“St Ann’s needs to raise two thirds of its income from donations so I want to make my own contribution and raise awareness of the need for support. Every day we do make a difference and although it’s a cliche, fundraising helps us care for people when they need it most.”
Kelly and husband Marc have already raised £5,500 for charity from various runs, mostly to support treatment of multiple sclerosis, a condition which affects her sister Donna Bentley, from Romiley.
Kelly, a member of Davenport Runners, added: “My fundraising from now on is for St Ann’s because we look after patients with all life-limiting illnesses, including MS and cancer.”
