Swimmer Lewis Coleman has been named sports ambassador for Leukaemia & Lymphoma Research.
Lewis, from Sheffield, raised more than £25,000 for the charity at a sponsored relay race earlier this year.
Swim4Leukaemia, held in Sheffield in February, saw 100 swimmers team up to break the Guinness World Record for the fastest 100 x 100m relay.
Lewis was inspired to help the charity after his mother, Mags, was diagnosed with acute lymphoblastic leukaemia in June 2012.
Her initial chemotherapy was unsuccessful, and she was entered onto a clinical drugs trial before undergoing a bone marrow transplant last year.
Lewis, who will represent England at the Commonwealth Games in Glasgow later this month, said: “My world was rocked when mum was diagnosed with leukaemia and I wanted to do my bit so that more people can have access to new drugs and clinical trials.
“It’s a real honour for me to become sports ambassador for Leukaemia & Lymphoma Research. The charity does amazing work researching blood cancer, and I have seen first-hand what its great work can do to help save lives. I’m really excited to be part of that.”
Emma Jones, regional manager for Leukaemia & Lymphoma Research, said: “We are delighted that Lewis has agreed to become our sports ambassador as he is an inspiration to so many of our supporters.
“His Swim4Leukaemia event highlighted to so many people what he and his family had gone through, and the importance of funding clinical drugs trials.
“It was a pleasure to support Lewis in his first fundraising journey for Leukaemia & Lymphoma Research. We were all inspired by his tenacity and ability to make things happen.”
