Amazing! I never even thought of relays or indoor women's 60m.
Where did you find that information?
Maybe you can help me with finding an answer to a question I have:
Can you find a list of all top tier male and female distance runners 800m to marathon (no sprints!) that have had a positive doping test in the last 10 years? I can't think of anyone major for EPO or anabolic steroids.
So far we have come up with : Mo Trafeh for EPO in luggage coming back from trip to Morocco- close enough to a positive test!, Maggie Vessy for a diuretic, Hazel Clark for the stimulant pseudoephedrine, and Mary Akor for Clenbuterol (and I personally do not consider Akor as top level)...
Can you find some more?
If not... then I think the US is actually doing a lot better than a lot of other countries.
