It’s hard to imagine it now, but two years ago Darren Graham weighed in at 185 kilograms and had a number of health concerns.

Fast-forward to today and the Tarneit man is in fighting fit shape thanks to a low-carb, healthy fat diet, which prompted him to jump back on his bike and get active.

“I’m off all medications now, for the first time in 20 years,” he said.

“After about a month or so, all my pains and arthritis went away. After I saw the science was working, it went from there.”

Mr Graham said he started cycling part-way to and from work in the city, gradually increasing the distance as his fitness improved. He also does longer rides at weekends with the Wyndham cycling group and easily racks up more than 100 kilometres on his bike each week.

“I decided to get a team of guys together from work and did Ride Daylesford, which was a 55 kilometre ride, and I did a half-marathon … and I thought, what’s next?”

It turns out, what’s next is a 65-kilometre bike ride along the Great Ocean Road.

This weekend, Mr Graham will be joining Tour de France winner Cadel Evans and thousands of others riding the Cadel Evans Great Ocean Road Race, where he hopes to rub shoulders with the cycling great.

The four-day road race kicks off on January 25. To find out more, go to www.cadelevansgreatoceanroadrace.com.au
