A Letchworth-based GP has been training hard ahead of the Chase the Sun cycle challenge, which will see her ride from dawn until dusk.

Sue Graham will take on the 205-mile challenge in memory of her nephew Peter Woodmansey, who died aged 17 from sepsis - three weeks after his leukaemia diagnosis.

The Birchwood Surgery GP - originally from St Albans - hopes her efforts will go some way to helping the charity fund potentially life-saving research.

Peter, who lived in York, was the grandson of Rennie Grove Hospice Care president and founder, Mary Groves.

Sue said: "Peter was an amazing and brilliant young man who lived his life to the full, touching so many people with his love, kindness and humour.

"His death was tragic. He was only 17, and he had a very short illness before he was diagnosed and died three weeks later.

"I decided to do some fundraising for Leukaemia UK with a cycling challenge called 'Chase the Sun'."

The challenge begins at sunrise on June 19 - 4.41am - at the Thames Estuary, and crosses to the west coast of England, finishing at Burnham-on-Sea at sunset at 9.30pm.

"It's going to be a long day," Sue continued. "I've been training really hard for it - I've done 6,000km, which has been tough, but worth it.

"Peter's death is heart breaking, and the loss unimaginable, but the bravery, courage and strength shown by him and his amazing family will spur me on through each and every one of the 205 miles I cycle

"By raising awareness and much-needed funds for Leukaemia UK, we hope to help with their ground-breaking research and care for those affected by leukaemia other blood cancers."

Sue has already raised £1,830 of her £2,500 target via her fundraising page.

According to Sue's chosen charity, someone is diagnosed with blood cancer every 16 minutes in the UK.

Leukaemia UK supports those affected by blood cancers through the uncertainty that may come with a diagnosis, and by funding research for better treatments and care.
