The International Testing Agency (ITA) has implemented a series of surprise, late-night anti-doping controls during the 2026 Tour de France, sparking significant debate among riders, teams, and the professional riders’ association, the CPA. The testing program, which has included visits to hotel rooms as early as 2 a.m. and 5 a.m., represents an expansion of the agency’s intelligence-led strategy to combat potential micro-dosing.
ITA Conducts Surprise Nighttime Anti-Doping Tests at 2026 Tour de France
The ITA, which assumed responsibility for the sport’s anti-doping program from the UCI in 2021, confirmed it obtained authorization from a French judge to conduct testing outside the standard WADA-defined window of 6 a.m. to 11 p.m. According to the ITA, such measures are reserved for limited and justified circumstances
where there is sufficient suspicion, such as abnormalities in an athlete’s biological passport, sudden performance upturns, or specific tip-offs.
Peloton-Wide Testing on Rest Day
While nighttime visits have drawn the most scrutiny, the ITA also executed a comprehensive biological passport operation during the Tour’s rest day. On that Monday, all 166 riders remaining in the race were visited by doping control officers between 8 p.m. and 11 p.m. to provide blood samples.

This rest-day operation was part of a broader testing mission that includes pre-competition screenings and ongoing monitoring throughout the race. The ITA stated that more than 600 samples were scheduled for collection across the 2026 event. The agency maintains that these additional blood samples allow for the assessment of hematological biological markers, strengthening the longitudinal monitoring of each rider’s profile.
Criticism and Official Support
The practice of nighttime testing has been labeled “strange” by race leader Tadej Pogačar and has faced harsh criticism from the CPA. Pascal Chanteur, vice-president of the CPA, questioned the involvement of the French judicial system, suggesting that judges granting the warrants may lack specialized knowledge of cycling. Similarly, EF Education EasyPost team manager Jonathan Vaughters remarked that while he supports the ITA’s efforts, he believes the bar for obtaining a judge’s warrant may not be exceptionally high given the sport’s history.

Stakes of Modern Anti-Doping
The shift toward intelligence-led, nighttime testing is intended to address the risks associated with micro-dosing, where performance-enhancing substances with short clearance times could theoretically be used to avoid detection during standard daytime hours. ITA director of testing Olivier Banuls previously emphasized that modern anti-doping has moved away from mass post-race controls toward a strategy focused on building long-term biological profiles.

Despite the controversy, the Tour de France continued as the ITA maintained its commitment to the program. The UCI noted that stakeholders collectively contribute 10 million euros annually toward the collection, analysis, and intelligence-gathering efforts that define the current anti-doping framework in cycling. As of the latest reports, the outcomes of the specific nighttime tests conducted on high-profile riders remain undisclosed.
