Working plumber Buster Martin ran Sunday's Roding Valley half marathon in Essex in five hours 13 minutes, and is now focusing on London's 26-mile event.
On finishing the run, the first words of the ex-member of rock band The Zimmers were: "Where's my beer?"
Mr Martin, who has 17 children, started work at Pimlico Plumbers in London three years ago because he was bored.
The Zimmers were featured previously on Neatorama. Mr. Martin doesn’t look 101, does he? Link -via Arbroath
