TV presenter Paddy McGuinness, preparing for a nearly 300-mile ultra-endurance cycling challenge for BBC Children in Need, credits Olympic cyclist Sir Chris Hoy for pushing him to his limits during training. McGuinness, inspired by individuals benefiting from the charity, will embark on the journey from Wrexham to Glasgow. Hoy, who is facing terminal prostate cancer, has provided invaluable advice despite his health struggles. The challenge will coincide with the annual Children in Need appeal, airing this Friday at 19:00 GMT on BBC One.
