I’m sure this will be unpopular, but…
If you are putting in the time and money and energy to go to the Olympics, you better damn well know the rules. The coach, the rider, the grooms, the owners, etc. all need to know. Yes, individual horses may take longer to clear a substance, but my feeling is that if you don’t know exactly what is in the creams, ointments, rubs, treats, etc., then you are too far removed from the care of the horse you are competing on. There is a zero-tolerance policy for the Olympics - you just have to take it very seriously if you want to compete there.
The Hong Kong labs are world class, and the B samples are processed by a completely different lab. They did their jobs and detected the substances on their list of drugs to test for. I’m amazed at the negative comments towards the labs here because they did their jobs.
Over 150 over-the-counter “nutritional” supplements can bounce a human athlete out of the Olympics and China did a mass campaign to warn their citizens that herbal remedies can also make them test positive. Avoiding substances that test positive is a challenge for humans and horses alike.
It is a shame for Courtney King because she’s just the highest profile member of the horse’s team. The grooms, the coach, the owners, and pretty much anyone else who had contact with the horse that could have exposed it to an illegal substance share in the responsibility. She certainly wouldn’t be the first high-profile rider to have discovered that someone accidentally used the wrong cream on the horse and it tested positive and she unfortunately won’t be the last. But this is where a concerted effort needs to be made to everyone involved with the horse to ensure that banned substances simply aren’t used close enough to test time that they might enhance their performance.
