Elite tennis players must report their location every day
Top athletes face a professional ban if they miss three unannounced drug tests, even if they are simply stuck in traffic or sleeping.
Professional tennis maintains one of the most rigorous anti-doping protocols in global sports. Players in the international testing pool, which includes the top 100 singles and doubles competitors, must provide the International Tennis Integrity Agency with their exact location for one hour of every single day. This requirement applies year-round, regardless of whether the athlete is competing, training, or traveling for personal reasons.
