If you are planning to watch the Isle of Man Classic TT races then you might see an unfamiliar site after all the bikers…

A former semi-professional rider and dad-of-two is preparing to take on the circuit on foot this year – followed by a support crew of four friends with a collecting bucket - to raise up to ?10,000 for Cancer Research UK.

Dave Binch, from Mansfield, Nottingham, will complete the parade lap around the island on the infamous Classic TT course on his Yamaha TZ250.

But after riding around the 150mph race he then plans to run the 37.8mile hilly course – the equivalent of one-and-a-half marathons - powered only by his trainers as well as a little grit and determination.

The 45-year-old, who trains with Mansfield Harriers, came up with the double challenge in aid of Cancer Research UK after being inspired by a friend's daughter who has been diagnosed with terminal cancer.

He said: "It's quite a unique event based around me achieving two major goals. One is to celebrate the race at the Isle of Man TT and the second is to try to run it.

"It really is two extremes – 150mph one day and then 4mph the next. But it was the diagnosis of my friend's daughter that prompted me to do something. Everyone has friends or family that have passed away from cancer and I just asked myself 'how can I help.'"

Project manager Dave, who took part in his first race on the TT course over 25 years ago, said when his wife Karine became pregnant with the first of their now-teenagers daughters Aimee and Abbie he abandoned two-wheeled transport and took up running instead and has completed fell runs a well as marathons.

The running part of the challenge will see him travel around the island on foot - at a more sedate pace of 4miles per hour - in a bid to raise ?10,000.

The roads are narrow and windy and his plan had to be adapted for safety. The route will see him take in Bray Hill, the aptly named Windy Corner, Hailwood Rise and the Snaefell mountain course – the highest peak on the island at 2,034ft above sea level.

Dave said: "I've never done anything like this distance before as it's one-and-a-half marathons. I don't really know how to train for this. The mountain section will be a big challenge and it's very undulating and awkward to get around. As well as preparing the bike, I've got to prepare mentally as well as sort out the legs and the stamina. The mountain section is certainly one big hill! But it will be a case of breaking down into smaller chunks and putting my head down and just putting one foot in front of the other.”

Dave has estimated the bike race will take about 30 minutes and the run at least 20 times that – around eight hours.

He will also be joined by friends and family, including wife Karine who will spend their wedding anniversary on September 1 watching the run.

All the money raised by Dave will go to Cancer Research UK, inspired by the story of his close friend's daughter Rachel Burton, from Matlock, Derbyshire, who was diagnosed with terminal brain cancer last summer aged 26.

Dave added: "I took her out on the back of the bike after her diagnosis around Derbyshire and we had a really nice day. She is such a nice lady, really unassuming. Once I took her out on the bike I thought there must be something I can do."
