What's the process? And let's use Brigid as an example too.
She crosses the finish line with a world record in the marathon.
What's the time frame until she is tested? 10 minutes? 30 minutes? Is her urine and/or blood tested? How long until those tests have results?
Not accusing her and sorry for my ignorance but I just imagine her taking a few tests within a half hour of finishing the race and we should know if she's tested positive or not within a day or two. Or is that just wishful thinking?
