We are in a doping era. How is this not obvious to everyone?
When the fastest runners are getting popped logic says no clean runners can really compete. And then we also know how easy the tests are to fool. It's simple. Big money is at stake. Get your heads out of the sand.
Doping surely works on Africans as well as Europeans and everyone else and is responsible for the records going down every other day this year.
The question is - do they all get the same drugs? Is it driven by individual runners or their team ? I have suspected some in NN running team, Hassan, many others. What about the top pros in the US, Japan, Europe?
