A KNUTSFORD swimmer clocked a personal best at the same time as helping to raise more than £20,000 for Leukaemia research.

Adam Frost joined a 100x100m relay team, including James Goddard and Rebecca Adlington, that swam at Sheffield’s Pond Forge as part of Swim4Leukaemia.

He posted a time of 51.1s, helping a 100-strong team to a Guinness World Record of 1:29.30.

“We beat the previous record by eight minutes,” said the 18-year-old.

“My PB was 52.37s; obviously a relay take over is slightly quicker, but it was a really good swim as I haven't posted a time that fast in two years.

“I saw Becky Adlington during and managed to speak to her properly about the event.

“She said she enjoyed it and was pleased to be helping out and the organiser Lewis Coleman, whose mum was diagnosed with Leukaemia last year, did a fantastic job. “ Frost, whose uncle died of Leukaemia a decade ago, contributed more than £800 towards the total.

“It was excellent,” he explained.

“It was quite emotional at the end; Lewis was in tears as was his brother and most of the crowd. But the atmosphere was incredible.”
