The issue for some people is the aim to qualify for the world championships in Hawaii. If they are clean and finish 4th in the age group and miss out and then find that one of the people who qualified ahead of them was suspected of doping and did a time close to the time professionals are doing they might be a tad pissed off.
Generally in running races I couldn't give a flying whatever either, same with the tri world really as I'm nowhere near qualifying standard and without a course of EPO never will be, but I can see why good athletes would be upset.
Sadly I think the WTC are more interested in the $$$, not sure we'll ever see random testing at IM, if they wanted people to play fair they'd do something more about the wholly obvious draft-fest at some races - Austria was a joke, not where I was obviously, there were only about 10 of us spread across a mile but on the part of the lap where the front end of the race goes the opposite direction it was a peleton.
Just let everyone dope if they want to and carry on as we have for forever, at least we get rid of the controversy and constant theorising over each winner of any grand tour.
To anyone not overly interested in the sport it's assumed that everyone dopes and that perception has stuck and I can't see that changing ever again.
Doping to get to Kona is a cheaper/quicker alternative to going down the legacy route for people who are not quite good enough to qualify but desperately want to go there, can see why people would take that route. As long as they only dope to get there and once qualified, stay clean 'til race day no one will ever know, assuming they are clever and pick a qualifier late in the previous season.
Not entirely sure what any of this has to do with football?
