It was a good question. Unfortunately, I think there are a lot of drugs in our sport. Simply because most races don't test. I would like to see a qualify and test type of program.
1) If you the event is a qualifier - FOR ANYTHING - and you earn a slot - you get drug tested. YOU as the qualifier, pays the fee to prove you are clean. This adds approximately $185 to whatever you qualified for if the prices I read about are accurate, but possibly lower.
2) At the event you qualified for, ALL registered athletes are subject to random drug tests - this would be paid for by the governing body holding the "championship".
3) ALL podium/prime award winners get drug tested. Paid for by the governing body holding the race.
4) ALL athletes who qualified for that race are now part of an out-of-season test program where you can be tested at any time until March 1 of the following year.
That's roughly how I'd do it.
After talking a bit, I said, "No, a championship is NOT a "true" championship unless there is extensive drug testing."
