Andre Bancala secures the invisible racing line of the Tour de France

Voiron – 23.07.2026: When the Tour de France peloton races over a crest, cuts through a roundabout or rushes through a town at high speed, Andre Bancala has long since completed his work. The coordinator for Departements de France has been one of the invisible architects of the Grande Boucle for almost three decades. On 22.07.2026, the 17th stage covered 174.7 kilometres from Chambery to Voiron – on roads that were meticulously checked before the first racing bike set out.

Bancala’s task does not begin on the morning of a stage. As soon as the route is set in the autumn, a network of road authorities, technical managers and local emergency services springs into action. It is about the road surface, narrow sections, traffic islands, construction sites and every point where a tightly packed peloton could lose its line. The Tour requires a route that is not only fast, but also controllable over many hours.

This is not background work, but race safety in detail. According to their association, around 3,000 employees of the French departements are mobilised every year before the start. During the race, a permanent technical team complements this work. Eight conspicuously yellow vehicles are part of the system, as are a mobile control centre and a technical rear guard. On the most critical sections, an average of up to 3,800 warning signs are installed.

For the riders, this preparation determines fractions of a second and often much more. A poorly visible traffic divider, loose gravel after the advertising caravan or an unprotected traffic-calming feature can trigger a chain reaction in the peloton at 60 km/h. That is why the Departements de France team not only checks the route, but also coordinates with the Tour organisers, the Garde republicaine, police and the affected departements on race day.

In 2026, the signage was further adapted. A dedicated warning sign for chicanes is new; at roundabouts and road narrowings, the number of notices is generally to be reduced from three to two. Where visibility remains difficult, such as on a descent, an additional notice may remain in place. The principle is clear: the warning must reach the professionals early enough without turning the road itself into an obstacle course of signals.

The 18th stage starts in Voiron on 23.07.2026 and runs for 185.2 kilometres to Orcieres-Merlette. For spectators, another major mountain day begins there. For Bancala and his team, it starts earlier: with the inspection of those metres of asphalt on which the sporting decision only becomes possible. The Gendarmerie also accompanies the race with personnel from several units to protect riders and the public along the route.
