It's a bit of both. If you're an athlete being tested at that level, you have to keep your country's antidoping agency informed of your whereabouts at all times. They will randomly send testers to wherever you are and you have a short time window, like 1-3 hours to show up. If you no-show 3 times (I think) it counts as a positive test and you're banned. I really don't know how someone could run in the trials with too many missed tests and not be allowed to race the olympics... I'm pretty sure the rules are the same.

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.

The simplest would be dead battery on a solo run. I've killed mine on a workout before. I've also delayed a workout to charge and ended up regretting it.

More likely you're young, mad fit, and have some energy you want to burn off with a friend. You've heard about the Olympic Village.

No way do I want to tell some official whose apartment I'm visiting.

If you missed 2 before the trials and another after? I could see someone being on final notice before the trials and then fucking up again.

But they didn't actually say how and when she was DQed, just that she missed the Tokyo Olympics due to breaking the whereabouts clause. There are clearly favorites at the trials and if someone 'should' have gone I could see announcers making the speculative leap.
