The athlete may have had a third failed test, but still had time to protest that. There have been examples where athletes filed changes to their schedule, but doping authorities missed those and ended up at the wrong place for a random test, for example.

(Having to file your whereabouts is horrendous, by the way. https://www.wada-ama.org/en/athletes-support-personnel/provi...:

“RTP athletes are required to provide the following whereabouts information on a quarterly basis:

- Home address, email address and phone number

- An address for overnight accommodations

- Regular activities, such as training, work, and school, the locations and the times of these activities

- Competition schedules and locations

- A 60-minute time slot for each day where they’ll be available and accessible for testing and liable for a potential ‘missed test’“

That “60-minute time slot” sounds somewhat reasonable, but (https://www.wada-ama.org/sites/default/files/2022-03/At_a_Gl...): “And remember, athlete can be tested anytime and anywhere – not just in their 60-minute time slot!”

Miss a plane? Plane delayed? You may have to inform your doping agency. A loved one suddenly ends up in hospital? Before you rush to go there, report where you’ll be.
