The presenter, who hosts the Sunday lunchtime programme on Radio 2, will complete the cycle on a BBC Children in Need customised and modified Raleigh Chopper – a bicycle popular with children in the 1970s.
Speaking about the challenge, the 51-year-old broadcaster said: “As a kid, I didn’t have much and used to be really jealous of my mates riding around on those bikes, so I’m really honoured to support BBC Children in Need by getting peddling to raise as much money as possible for the charity.
“‘No likey, no bikey’ just isn’t an option,” he joked, refashioning his famous Take Me Out catchphrase.
McGuinness has been a Radio 2 presenter since April 2024 and is best known as the host of shows including Take Me Out, Top Gear and Question of Sport.
