While 166 exhausted Tour de France riders tried to recover from 2 punishing weeks of racing, anti-doping officers arrived at team hotels across Haute Savoie with blood collection equipment.
Reuters reported that the International Testing Agency collected samples from every rider still competing during the second rest day on Monday, July 20. The operation came before the 26.1 kilometre stage 16 time trial from Évian les Bains to Thonon les Bains.
Each sample added fresh information to the rider’s Athlete Biological Passport. Testing the full peloton was significant, but the timing carried even greater weight.
Just 1 day earlier, Jonas Vingegaard and Tadej Pogačar revealed that officers had woken them at 2 a.m. and 5 a.m. before stage 15. Those visits turned a routine discussion about enforcement into a sharper debate about sleep, recovery, performance, and rider safety.
Every Remaining Rider Entered the Same Process
Cycling Weekly reported that testing officers visited every team during the rest day and collected blood from all 166 remaining riders during normal evening hours. The ITA later confirmed that the entire peloton had been included.
That did not mean officials considered every rider a suspect. A mass operation gave investigators a common reference point after more than 2 weeks of racing, illness, recovery, altitude exposure, and accumulated fatigue.
All Tour starters had already undergone blood testing before the race. Stage winners, classification leaders, and competitors selected through intelligence or risk analysis also faced regular controls during the event.
The ITA explained before the Tour that its programme would combine biological data with performance analysis and intelligence. The rest day sweep added another layer to that work before the decisive Alpine stages.
Testing the full field also removed any immediate concern about selective treatment. The yellow jersey, domestiques, sprinters, climbers, and riders near the bottom of the standings all entered the same process.
That breadth matters in a sport where public attention often settles almost entirely on the race leader. This operation made clear that the scrutiny extended across the peloton.
Each Sample Strengthens a Longer Biological Record
The Athlete Biological Passport does not depend on finding a prohibited substance in a single tube of blood. It tracks selected biological markers over time and builds an individual profile for each rider.
One sample rarely catches a cheat in the act. It adds another point to a long term biological map.
Experts compare each result with earlier readings and search for changes that normal training, racing, recovery, illness, or environmental conditions cannot easily explain. An unusual movement can trigger closer monitoring, targeted controls, or an expert review.
The panel can clear the reading, order more tests, or begin proceedings if the wider evidence indicates the use of a prohibited substance or method.
As Reuters noted in its report on the mass operation, the additional samples allow specialists to assess changes in blood markers across the race. Cycling has used biological passport monitoring since 2008, making the Haute Savoie sweep part of an established investigative system rather than a 1 night search for a positive result.
Its value also extends beyond the current Tour. Officials can compare a sample collected during the rest day with results taken before the race, during later competitions, or through future out of competition controls.
Overnight Controls Changed the Argument
The full peloton operation took place during ordinary evening hours. The controls involving Vingegaard and Pogačar did not.
Vingegaard said officers knocked on his door at 2 a.m. and kept him away from his room for around 40 minutes. Pogačar faced his test at 5 a.m. and later said he could not return to sleep.
Cyclingnews reported that both contenders accepted the need for strict testing but questioned the damage caused by the timing.
The Guardian cited reporting from L’Équipe that a Paris judge had authorized the overnight controls after the ITA sought approval under French law. UCI rules generally restrict testing between 11 p.m. and 6 a.m. unless specific conditions apply.
The ITA defended the operation, arguing that effective controls must sometimes occur outside daytime hours. Officials may need to act unpredictably when investigating methods designed to exploit short detection windows.
Pogačar accepted that principle. He said he would cooperate if officials considered night testing necessary to prove the riders were competing clean. His objection focused on what the timing did to his recovery.
“It is a bit shit when you sleep for 4 hours in 1 day in the middle of a 3 week Tour,” Pogačar said as he explained the physical cost of the early morning visit.
His frustration captured the real fault line. Riders are not asking to avoid scrutiny. They are questioning whether officials can achieve the same objective without taking away a night of recovery during the hardest race in professional cycling.
Vingegaard’s Crash Raised the Stakes
Vingegaard later crashed out of stage 15 with a fractured collarbone. No evidence has established that disrupted sleep caused the accident.
Pogačar nevertheless raised the possibility that fatigue had affected his rival’s concentration. As Cyclingnews reported, he presented sleep loss as a potential factor rather than a proven explanation.
That distinction matters. It would be wrong to draw a direct line between 1 interrupted night and a racing accident. The episode still gave the wider debate a harder edge.
Sleep is not a comfort during a 3 week Grand Tour. It is part of an athlete’s preparation.
Riders depend on it to repair muscle damage, restore energy, manage stress, and maintain concentration. On narrow descents and crowded roads, a brief lapse can end a race or cause serious injury.
Authorities cannot dismiss those risks. They also cannot make testing so predictable that sophisticated doping becomes easier to conceal.
The answer is not to ban overnight controls. It is to set a high threshold for using them and require officials to show why normal hours would not serve the same purpose.
The Riders Union Calls for Smarter Enforcement
The Cyclistes Professionnels Associés responded by calling for a more intelligent and proportionate fight against doping.
Cyclingnews reported that the riders union supported strong enforcement while demanding greater protection for health, recovery, and equal competition.
Its position was not a call for fewer controls. It was a demand for better ones.
Testing built around intelligence, biological data, performance trends, and targeted analysis offers more value than disruption for its own sake. The ITA has already described its Tour programme as intelligence led and based on changing risk assessments.
Monday’s sweep strengthened the union’s argument. Officers reached all 166 remaining riders during a controlled evening window and still collected meaningful biological information.
There may be exceptional cases when investigators need to test during the night. Such controls should remain exceptional because the cost to a rider’s recovery is immediate and impossible to reverse.
Cycling Must Protect Credibility Without Sacrificing Recovery
The mass blood collection strengthened the Tour’s anti doping programme. It expanded the available data, treated the full peloton consistently, and showed that officials can conduct a major operation without waking riders in the middle of the night.
That does not make every overnight visit improper. Unpredictability remains an important weapon against doping methods designed to evade conventional controls.
Cycling cannot afford weak enforcement. Its history has removed that luxury.
The sport also cannot treat sleep as acceptable collateral damage without a clear and exceptional reason. The Haute Savoie sweep showed that credibility and rider recovery do not always have to compete.
The next step is making sure they rarely do.

FAQs
Were all Tour de France riders drug tested?
The ITA collected blood from all 166 riders still racing during the second rest day to strengthen each rider’s biological passport.
Why were Pogačar and Vingegaard tested during the night?
Officials may use unpredictable timing when normal hours could miss short detection windows. A Paris judge authorised these controls under French law.
Did the overnight test cause Jonas Vingegaard’s crash?
No. The article states that no evidence directly links Vingegaard’s interrupted sleep to his stage 15 crash.
How does the Athlete Biological Passport work?
It tracks selected blood and urine markers over time. Experts investigate unusual changes instead of relying on one sample to reveal a banned substance.
What does the riders’ union want changed?
The union supports strong testing but wants smarter, proportionate controls that protect sleep, health, recovery and equal competition.
