A Paris judge authorized night-time doping tests for Tadej Pogacar and Jonas Vingegaard in the early hours of July 19. This decision came after the International Testing Agency (ITA) petitioned for tests to be conducted outside the regular hours of 6am to 11pm, ahead of Stage 15 to Plateau de Solaison in the Savoyard Alps.

• Vingegaard was tested at 2am, while Pogacar faced his test at 5am.
• Pogacar criticized this timing, calling it "inhuman," and suggested it negatively impacted Vingegaard's performance, potentially contributing to his crash that resulted in a broken collarbone and withdrawal from the Tour.
• Vingegaard mentioned, "I was sleeping very well. It’s good that they test, but when it’s affecting performance and your sleep, I don’t think it’s so good."

The UCI's regulations stipulate that night-time tests require serious suspicions of doping, and the judges have the authority to approve such requests. The decision faced backlash from riders and team staff, including Remco Evenepoel and Matteo Jorgenson, who labeled it disrespectful to the athletes.

The ITA acknowledged the disruption caused by night-time testing but emphasized its commitment to maintaining the integrity of cycling. It is reported that up to five teams, including UAE Team Emirates XRG and Visma Lease-a-bike, have undergone similar nocturnal tests during the Tour.

This testing method targets micro-dosing of performance enhancers, a practice that poses challenges for detection. Jonathan Vaughters, a team manager and former teammate of Lance Armstrong, supported the tests, indicating that they could have prevented years of doping scandals if implemented earlier.

The Tour concludes in Paris on Sunday evening, but the timeline for the test results remains unknown, with the ITA committed to publishing outcomes only in cases of rule violations.
