The Fort Worth Press - Designing a Tour de France route: a three-year labour of love

Work on each year's Tour route begins three years ahead of time, when Tour director Christian Prudhomme settles on the city that will host the Grand Depart for that edition.

After that, he decides which direction the race will set off in, and starts to pick the departure and arrival towns for each of the 21 stages from a list of 300 candidates -- including 50 foreign ones.

Several factors go into that decision-making process.

"If we only took sporting issues into consideration, every year we would be there," Prudhomme told AFP in his office before the Tour, pointing to the southern half of a map of France pinned to his wall.

"Because that is where you can do anything you want: flat, medium mountains, very tough (mountains).

"But then you also have Brittany, the land of cyclists; the north, who gave us an incredible reception last year; Normandy, where every time there is a crazy number of fans.

"Over a period of four or five years, we go just about everywhere."

Beautiful scenery is a key consideration because "people also watch the Tour for the beauty of its landscapes".

Special attention is also paid to weekend stages and the one on Bastille Day -- France's national holiday -- as those attract the largest television audiences.

And then there are the non-negotiables.

"You could put 50 mountains but if there isn't the Tourmalet, Galibier, Ventoux or Alpe d'Huez, people will say that there were no mountains," said Prudhomme.

- '10 miracles' -

And then there is the sense of history and sentiment, such as when the Tour passed through the village of Castelnau-Magnoac, the birthplace of France's national rugby team captain Antoine Dupont ahead of the 2023 World Cup in the country.

Back in 2014, there were seven stages that largely followed the World War I frontline of 100 years earlier.

"I love it when a stage can be viewed in different ways," said Prudhomme.

Once he has decided the 21 departure and finish towns, it is over to route director Thierry Gouvenou to lay out the exact 3,000-kilometre path that the peloton will embark upon.

That begins for the following year once the Tour finishes at the end of July.

"At the end of August, Christian gives me the list of stage towns," Gouvenou told AFP before the Tour began.

"From that point, it takes up my whole time. Generally, I design the course in one month because it has to be finished by September 25."

Firstly, he uses mapping and cycling apps to design the route, while he also receives a plethora of messages from cycling enthusiasts with suggestions.

Then, he gets in his car to visit potential "trouble spots" where "things could go wrong".

The main issue is town centres, which can contain unexpected hazards -- such as traffic calming infrastructure which can provide obstacles to the safe passage of a peloton of more than 180 riders.

Once the route is fixed, Gouvenou sets about driving the course of each and every stage.

"I don't do it alone. We're in teams of two. We jot down everything: the dangers, the layout, and we decide already on where to have the intermediate sprints and the climb summits."

The Tour route is then revealed in October in Paris, nine months before the race begins.

Although, there are always some late crises, such as for the second stage this year when the route had to be diverted away from an area that had seen an outbreak of swine flu.

"The regions are hyper-vigilant. There are often 10 miracles achieved" to avert last-minute problems, said Gouvenou, a former professional cyclist.
