Vernon Kay is just hours away from starting his 115-mile charity challenge – and he's just received encouragement from a true Hollywood legend. The 49-year-old Boltonian is aiming to complete the Ultra Ultramarathon this week, which starts at Victoria Park in Leicester tomorrow morning (Tuesday). Traveling 115 miles in four days, he aims to complete the challenge at Bolton Wanderers Stadium on Friday (November 17) live on the Radio 2 Zoe Ball Breakfast Show. He previously posted on his Instagram Stories “We're on our way,” along with a photo taken on a passenger bus, although the exact route he'll be walking has yet to be revealed. But on Zoe's show today (Monday), Vern explained how he will summit Kinder Scout in Derbyshire as part of his efforts. Although he is in good physical shape, he said he felt pain in his knees while running in Skegness today. Vernon said: "Skeggy was good, and then at the end of it, I had a little bit of a knee twinge. I thought, 'What's that, that's not said hello before'. "I've had lots of aches and pains and lots of strains, but people have been looking after me and we've kind of come to an apex of disorder on my left side." He explained that he has a 'dodgy IT [iliotibial] band', an MCL [medial collateral ligament] that 'wants to come and play', I've got something wrong with the nerves in my toes... But apart from that, I'm alright." Despite his long list of physical problems that would have discouraged a lesser person, Vernon remained in good spirits. And if you need extra motivation to get through the tough times, Arnold Schwarzenegger's help is always at hand. The legendary Hollywood strongman was on Zoe's show on Friday, October 27, speaking on a number of topics and was asked to give Vern a pep talk. The former California governor did not disappoint. Arnie said: "It shouldn't be a problem if that's [Vernon's] goal. And if you can visualise your goal and see yourself at the finish line, I think you can do it. "Seeing it, visualising it, believing it, is achieving it. He will make it, there's no two ways about it, because if that's his goal there's nothing that can stop him. "As long as he doesn't get any injuries and he just has to focus on his goal and that's the bottom line." As the latest addition to Radio 2 after replacing Ken Bruce earlier this year, Vernon was challenged to travel from Leicester's Victoria Park to Bolton Wanderers' football stadium in his hometown, powered only by power with two feet. This is to raise funds for the BBC Children in Need 2023 appeal. He will be challenged to walk different parts of the track each day. To mark the end of the challenge, Zoe will host her popular radio show from Bolton Wanderers Football Stadium, on Burnden Way in Horwich, to cheer on the DJ as he crosses the finish line in his hometown.
