Hugh Porter took to the track at Aldersley Stadium, in Wolverhampton, along with dozens of other riders, to raise money for Compton Care.
The Commonwealth Gold medal winner did 80 laps of the track, roughly 22.7 miles, in 90 minutes as part of the event the day before his 80th birthday.
The venue – Aldersley Stadium – was chosen as it was where the broadcaster trained ahead of his World Championship successes.
And people who took part were invited to the the mayoral suite in the city the following day, through special invitation.
Mayor of Wolverhampton, Councillor Claire Darke, said: "Hugh and I wanted to thank everybody who had contributed and took part to make it happen.
"And it happened to coincide with his birthday, so we had a bit of a birthday bash for him and it worked out very well for everyone.
"It worked out for the people who did all the hard work and Hugh was fundraising for a good cause, Compton Care, and it was praise for all the good work he does.
"I think it's good to get these personal connections with people who came to the event."
The Wolverhampton-born cyclist, who is a patron of Compton Care, said: "It was absolutely wonderful – it was a wonderful idea of the mayor's and it was a big thank you to everyone involved.
"It gave me an opportunity to invite quite a lot of the riders, who are my pals, who rode the event with me.
"It give it a nice friendly feel and it was so lovely.
"I've had two absolutely memorable days I will never forget – it's just been wonderful."
