Guillaume Martin-Guyonnet and Clément Berthet of Groupama-FDJ United crashed during the inaugural team time trial of the 2026 Tour de France on Saturday, July 4. The incident marks the first recorded fall of the current edition of the race, according to reports from the event’s opening stage.
What happened during the Groupama-FDJ United crash?
During the high-speed team time trial, Guillaume Martin-Guyonnet and Clément Berthet lost control of their bicycles and went down. Team time trials require riders to maintain a tight formation at speeds often exceeding 50 km/h, meaning a single mistake can trigger a chain reaction. Both riders were involved in the fall, which interrupted the Groupama-FDJ United squad’s momentum during the opening discipline of the Grande Boucle.

The crash occurred on Saturday, July 4, during the first stage of the 2026 competition. While the team time trial is designed to test collective strength and synchronization, the technical nature of the course contributed to the first crash of the tour.
How does this impact the riders and the team?
A crash in a team time trial is particularly damaging because the team’s overall time is typically taken from the fifth rider to cross the line. When two riders fall, the remaining teammates must either wait to regroup or push forward, potentially losing critical seconds that affect the general classification (GC) standings from day one.
For Martin-Guyonnet and Berthet, the immediate concern is physical recovery and equipment damage. In the context of a three-week race, early crashes can lead to lingering soreness or “road rash” that hampers performance in the subsequent mountain stages. Groupama-FDJ United will now need to assess whether both riders can maintain their roles within the team’s tactical plan for the remainder of the Tour.
Why are team time trials risky for the peloton?
Team time trials (TTT) are among the most stressful disciplines in professional cycling. Riders operate in a “paceline,” where the lead rider cuts the wind for those behind. The followers must stay inches from the wheel of the rider in front to maximize aerodynamic efficiency.
If a rider deviates slightly from the line or hits a patch of uneven road, the following riders have almost no time to react. This creates a high probability of “pile-ups,” as seen with the Martin-Guyonnet and Berthet incident. Unlike a standard road stage where a crash might only affect a small group, a TTT crash can derail the entire team’s strategy for the opening day.
For those unfamiliar with the format, the TTT is a race against the clock where the team works as a single unit. It is a stark contrast to the individual time trial, where the rider is alone against the clock, or the mass-start stages where the peloton moves as a large, fluid group.
What is the current status of the 2026 Tour de France?
The 2026 edition has begun with the intensity typical of the world’s most prestigious cycling race. The opening team time trial serves as a barometer for team cohesion and physical readiness. While the crash for Groupama-FDJ United is a setback, the race continues to move toward its first major climbs.

The Tour de France remains the pinnacle of the sport, demanding extreme endurance and tactical precision. Early accidents, while common, set the tone for the caution and aggression riders will employ as they navigate the French countryside over the next 20 days.
The next confirmed checkpoint for the race will be the start of Stage 2, where the peloton will transition from the synchronized effort of the time trial to the unpredictable dynamics of a standard road stage.
