They have one rule: you must wear a helmet.

They are Les Increvables, a group of cyclists based out of Brossard, Que. For three years, the group has planned a millennium project. This summer, the project came to fruition as they set out from Vancouver, B.C. Their seven-week bicycle journey will take them more than 5,000 kilometers from the west coast back to their homes near Montreal.

The group arrived in Weyburn on Sunday evening after travelling 170 kilometres from Ponteix, Sask. They planned to stay in Weyburn for a day to rest and fix their equipment. So far, the trip has had it's share of surprises.

"The roads are straight in Saskatchewan but not flat. There is a little grade of one or two degrees. As a cyclist, you feel it. It's not really flat. The wind is a prevailing factor here, too," said cyclist Gilles Champoux in his native tounge.

"We were amazed not to see more oil pumps. We thought we would see more. It surprised us - the wide open fields, the colours, green, blue, yellow. Also, the weather changes rapidly from cloudy to sunny to black, much more than in Quebec."

Les Increvables has almost the same number of females and males in their group. Not all of the members were able to make the cross-Canada journey. There are 15 cyclists along with two drivers commanding the vehicles carrying supplies, baggage, camping equipment and tools. The youngest member of the tour is 37 years old, and the oldest is 67.

After studying the maps and travelling over the Trans-Canada Highway, Champoux and the group decided to take the No. 13 highway across the Saskatchewan prairie.

"We didn't want to take the Trans-Canada. It's good for cars, but there's nothing to see. We expected there to be service problems with the Trans-Canada; everything is about 100 kilometers apart. We travel slower than cars. There are lots of villages on the No. 13, but we did not know there would be few services in those villages," explained Champoux.

"The people are very nice around here and the scenery is better. The drivers are fantastic. We usually ride three across, and the drivers pass very politely and wave," he said.

Besides doing their laundry and fixing their bikes, some members of the group checked out the Soo Line Museum. For Champoux, the museum tour was enlightening.

"I learned more about the two people I know of from this area: Tommy Douglas and Eddie Litzenberger. I knew Litzenberger played with Chicago but I didn't know he played for the Canadiens. I remember he was a good fighter," Champoux said.

Les Increvables left Weyburn on Tuesday morning for Carlyle or Redvers, depending on road conditions and the weather. They plan to reach Montreal by August 19.
