Buster Martin: Man who claimed to be the oldest-ever marathon runner at the age of 101

Buster Martin, who died on 12 April, claimed to be the oldest-ever marathon runner at the age of 101. He ran the 2008 London Marathon in just under 10 hours, raising £20,000 for charity, and expected to be recognised as the oldest person to complete the distance, but was refused the accolade because he was unable to verify his age, amid suggestions that he could have been as "young" as 94.

Several months after his marathon run, Martin claimed to have been issued a passport with a date of birth verifying his age. Guinness World Records said they would have needed a birth certificate to prove the record. "It's not about the world record," he said at the time. "The only Guinness I am interested in is a pint of Guinness."

Martin worked as a van cleaner at a London plumbing firm until his death. He features in a film called How to Live Forever by the American documentary-maker Mark Wexler which is due for release in the US in May.
