In Lille, at the hub of the drugs investigation, prosecutors are preparing "a battle plan", and the French National Assembly will debate a new, tougher law against doping in sport. The sports minister, Marie-George Buffet, is calling for heavier custodial sentences after the detention of three team doctors, two team managers, two masseurs, and one rider following police operations during the Tour.
If nothing else the scandal has spurred action throughout sport with the International Olympic Committee meeting on 20 August, and a November get-together of riders, managers, and top officials to search for a formula for a "clean" sport.
Cycling's governing body, the Union Cycliste Internationale, has, over some 30 years, punished riders caught by doping controls. They never went for the suppliers and those who administered the drugs.
Yet since 1989 it has been a criminal offence under French law to "incite, facilitate, use, or administer doping products to athletes." New penalties will mean five years and a 500,000 French francs (pounds 51,000) fine for the purveyor, and seven years plus a fine of a million francs for inciting the use of drugs.
Only France has this law and the Tour and its teams felt the force of it when the Festina team's Belgian masseur, Willy Voet, was arrested and charged with smuggling doping products into France almost a month ago.
Prosecutors in Lille plan to interview more riders and managers from other teams, plus those in high positions in cycling. "We want to have enough elements to prove that the world of cycling knew what was going on," a justice source said, adding that they were not short of offers of potentially useful information.
Fears that the Tour could not survive the scandal subsided as the 85th edition of France's most important annual event reached Paris. The Tour is big business, rating third in size and prestige behind the World Cup and the Olympic Games. It works with high profile companies such as Fiat and Coca-Cola, who, along with the French bank Credit Lyonnais and Champion supermarkets, provided between 17m and 20m francs of the Tour's budget of 250m.
There has already been a flicker of doubt about the sport's image with the cancellation of the first big-money apres-Tour race. A source at one sponsor said: "It is much too early to appreciate the consequences, but there is anxiety about the notoriety that has come to the Tour. We do not want to make hasty judgements but we are very attentive about how the problems will be controlled."
Nicolas Chaine, the communications director of Credit Lyonnais, told the French newspaper Le Monde: "I am not being hypocritical but it is obvious no one can race day after day on mineral water and salad. The substances used by the riders need to be identified. The Tour is solid but it needs appropriate controls."
The attitude of team sponsors could affect how often they race in France. The speed with which four Spanish teams on the Tour fled over the border, and the decision by riders with the Dutch team TVM could hint at an answer to that question.
Marco Pantani claimed that he had won "the cleanest Tour" because police raids had made it so. He has an offer of a million francs a month for three years, but at the back end of the field 10,000 francs a month is a common wage.
He suggested that if riders were willing to take drugs "they find themselves among the best, winning much money, and enhancing their sponsor's image. Those who don't find their performances lagging along with their salaries. They are almost condemned to take the drug."
That is the philosophy of many in the sport. If the French justice system can crack down, then those who control cycling should toughen up too. They could start by overhauling the crowded racing calendar which runs from February to October, and the points-ranking system which governs entry into the Tour and can determine a rider's salary. That can tempt a weary rider to turn to artificial aids.
THE MEN UNDER INVESTIGATION
A 53-year-old Belgian, employed as a masseur by the Festina team. Detained after customs search at Neuville-en-Ferrain discovered 400 vials and capsules of doping products in the team car he was driving, three days before the Tour began in Dublin on 11 July.
