Back in the 1940s Jamie Stuart, was a member of Shettleston Harriers, and was Scottish Two Mile Steeplechase champion in 1948.
When he was in his sixties, he ran five marathons in Glasgow and London, and raised thousands of pounds for churches and charities including Save the Children Fund and The Glasgow Lodging House Mission.
Now 93, and a well-known Glasgow author, the indefatigable Mr Stuart said he was proud to be one of the 4,000 baton bearers in Scotland.
"I'm very excited about it," he said a few hours beforehand.
An elder at High Carntyne Parish Church for 49 years, he added: "I think the whole of the church will be there, waving me on.
"I'm so proud to have been selected to carry a baton that will be opened by the Queen on Wednesday."
At the other end of the age-scale, teenage brothers Daniel and Alex Richardson, both of whom are British age-group champions in weightlifting, both helped to take the baton down Sauchiehall Street.
"It was brilliant, really exciting," said Daniel, 14.
"I never realised how exciting it was until I actually did it.
"All these people cheering you on was just brilliant."
His brother Alex, 13, said: "It felt brilliant, seeing everybody just watching me."
