The final weeks of the Tour de France test not only the elite contenders vying for the yellow jersey, but also the riders fighting simply to survive the high mountains and make the time cut. During the grueling stages leading into Nice, the peloton splits into distinct worlds: the fierce battle at the front, and the collective struggle of the gruppetto far behind, where exhausted riders navigate brutal climbs under intense physical strain.
For the riders trailing far behind the main group, the final mountain stages present an unrelenting physical test.
Behind the struggling riders, race support vehicles traverse the winding Alpine roads under unique conditions. A day spent inside the sweep vehicle—the official broom wagon tasked with picking up riders who abandon the race—offers a stark window into the attrition rate of a Grand Tour, where race officials witness firsthand the physical toll exacted on the field.
The Gruppetto’s Battle Against the Clock
According to race coverage from Le Télégramme, participants in the gruppetto finish stage efforts completely spent, describing the penultimate mountain tests as a long ordeal. Riders must balance conserving energy for the following day with the immediate necessity of conquering steep, relentless gradients.
Team carriages and support staff monitor time gaps closely, calculating splits on every hairpin turn to ensure their remaining athletes avoid elimination ahead of the final procession.
Inside the Sweep Vehicle on Mountain Stages
While the leaders race for stage victories, the race’s official sweep vehicle—known in French as the voiture balai—follows the absolute rear of the race.
According to reporting from L’Équipe, staff members inside the sweep vehicle spend hours tracking the shattered remnants of the race, ready to assist riders who can no longer turn the pedals.
