TWO brothers helped to smash a swimming world record and raise money for a charity which has helped their mother to fight leukaemia.

Lewis Coleman, aged 21, and his 10-year-old brother Oliver, were part of a 100-strong squad which broke the 100x100m relay record, posting a time of one hour, 29 minutes and three seconds.

Oliver, a pupil at Greenmount Primary school, started the first leg, while Lewis completed the final leg.

The previous record stood at one hour, 37 minutes and 53 seconds, but was broken with the help of swimming stars such as Rebecca Adlington, Fran Halsall and Karen Pickering who swam 100 metres each.

The event at the Ponds Forge International Sports Centre in Sheffield on Saturday raised more than £26,000 for blood cancer charity Leukaemia and Lymphoma Research.

Lewis’s mother Mags, aged 48, was diagnosed with acute lymphoblastic leukaemia in June, 2012, and has since undergone chemotherapy and a bone marrow transplant. The family also received good news from doctors, who said that treatment had been successful.

Lewis, a member of the Great Britain swimming team, said: “It’s been an absolutely fantastic day. Everyone’s support has been overwhelming.

“My world was rocked when my mum was diagnosed with leukaemia and I decided I wanted to raise money to help beat blood cancer.”

Rebecca Adlington, a double Olympic gold medallist, added: “I wanted to do a decent time just to help Lewis. It’s great to be here.”

Mags, who lives in Tottington with husband Joe, said: “It’s absolutely amazing what he has done. We are very proud of him.”
