The Port Fairy Cycling Club's tribute to the famous Paris-Roubaix - known as the "Hell of the North" - has been extended by 12 kilometres and incorporates an extra five km of gravel terrain.

The Paris-Roubaix, which took place last Sunday, is a 257km bike race in northern France renowned for its rough surface and cobblestones.

Port Fairy Cycling Club President Jason Puschenjak said he was excited about the updated course.

"We're putting in an extra section, an extra lap of gravel," he said.

It's also the first time participants will pedal on gravel as they cross the finish line.

The race, in its fifth year, will finish on the Port Fairy to Warrnambool Rail Trail at the Toolong picnic area near Badhams Road.

Puschenjak said the changes were made to extend the gravel section of the race.

He said the club normally cycled around Toolong and the special race incorporated a couple of rail trail sections to give a "cobbled classic feel".

Part of the challenge for riders will be avoiding a punctured tyre after six riders sustained punctures last year.

The handicapped 60km race, which comprises of 43kms of road riding and 17km of gravel, will start at 2pm at Toolong Hall on Saturday.

There is a junior race which starts at 1pm.

Puschenjak said he expected about 20 juniors and 60 senior riders to participate.

He said those wishing to enter the race should contact the Port Fairy Cycling Club on its Facebook page.
