Lloyd has spent 14 years raising £1.25million for cancer charities.  He is known to millions as the man who spent five days and eight hours completing the London Marathon for charity while wearing a 120lb deep-sea diving suit.

But there is much more to Lloyd Scott. The 41-year-old has devoted the past 14 years to raising more than £1.25million for cancer charities. His feats include climbing Mount Kilimanjaro and trekking hundreds of miles across the Sahara, the South Pole and the Himalayas.

The father of three dedicated his life to good causes after he was diagnosed with leukaemia while working as a firefighter in 1987.

Lloyd, who lives in Rainham, Essex, says: “They said if I didn’t find a bone-marrow donor, I would only have three or four years left.”

In a million-to-one chance, the Anthony Nolan Trust found him a donor within months, which almost certainly saved his life.

Lloyd then left the London Fire Brigade and devoted himself to good causes. He now works for CLIC – Cancer and Leukaemia in Childhood – as a liaison officer and spends much of his free time championing the charity’s work.

He says: “I want to show other sufferers that there is hope; that it can be overcome.”

Lloyd’s next project is a 2,500-mile bike ride across Australia – on a penny farthing.
