International Testing Agency (ITA) officials continue to conduct unannounced, middle-of-the-night anti-doping controls at the Tour de France, targeting high-profile contenders including Remco Evenepoel of Red Bull-Bora-hansgrohe.
The Rationale Behind Overnight Testing
The International Testing Agency (ITA) maintains that testing at 2:00 a.m. is a proven method to curb the use of short-acting performance-enhancing substances. According to Jonathan Vaughters, team principal of EF Education-EasyPost and a former professional cyclist, this strategy directly targets the biological window where micro-dosing would otherwise go undetected.
Vaughters noted on social media that had such late-night protocols existed during his racing career, they might have prevented the systemic doping issues that defined that era of professional cycling. By catching athletes during their recovery cycles, the ITA aims to ensure the integrity of the race, a sentiment echoed by Ralph Denk, manager of Red Bull-Bora-hansgrohe. While Denk acknowledged to German broadcaster ZDF that waking riders at night complicates physical recovery, he stated that these measures are necessary for the sport’s credibility.
Athlete Impact and Calls for Reform
The practice has sparked significant backlash from the peloton, particularly following the withdrawal of two-time champion Jonas Vingegaard, who crashed shortly after being subjected to nighttime testing. The Association of Professional Cyclists (CPA) has officially called for a reform of these procedures, describing the current approach as inhumane.

The debate highlights a tension between the need for a clean sport and the physiological requirements of elite athletes. While team managers like Denk express understanding of the regulatory necessity, the consensus among riders is that the current implementation of these anti-doping regulations places an undue burden on their ability to perform at the highest level during the three-week grand tour.

Frequently Asked Questions
Why does the ITA test riders at night?
Testing at night is used to detect micro-dosing of substances like EPO and hGH, which have short half-lives and are difficult to catch during standard daytime testing windows.
Are night tests permitted by cycling regulations?
Yes, current anti-doping regulations allow for out-of-competition and in-competition testing at any hour, provided the testing agency deems it necessary.
What is the reaction from the cycling community?
Opinions are divided. While some team managers believe it is essential for a “clean” sport, the Association of Professional Cyclists has criticized the practice as inhumane and is advocating for reforms to the current testing protocols.
