Don't get me wrong, I am completely against the use of performance enhancing drugs - I'd like to think that we all compete on a level playing field and success is a reward for hard work, dedication and sacrifice - and so am very much in favour of drug tests, but being part of a national registered testing pool can seriously impact on your life.
After winning a silver medal at the 2011 World 100k championships, I had my first experience of in-competition drugs tests. After running for so many hours, peeing into a cup in front of a witness is not the easiest thing to do (especially as every muscle protests at the thought of you getting up again once you've sat down). There were no prizes for the event, and the medals didn't even have proper ribbons, but it was a world championship event run by the IAAF (the International Amateur Athletics Federation) and so was subject to agreed rules and regulations. It was actually several months after the race that I received notification that I was now to be included on the national anti-doping register.
