August 20, 2026

The tests, conducted by the International Testing Agency—will cover both in-competition and out-of-competition scenarios, with mandatory testing for podium finishers and random selection for other participants, including amateurs. Refusing a test is treated as an anti-doping violation, and while organizers say the number of controls will be twice last year’s, they have not disclosed exact figures or the blood/urine split.
