There is a Q&A in the Denver Post with Dathan Ritzenhein(we just put it up on the homepage and here is the link:

)
and John Meyer throws this out there:
Among the theories out there is that foreign competitors are less likely to use illegal performance-enhancing drugs in the marathon, making it easier for Americans to compete. Do you agree?
I've never heard this theory before. Has anyone else? Having seen a video of EPO vials of a top marathoner, I don't buy it. If people are going to cheat and use blood boosters, transfusions, etc, why would they do it in the 5k or 10k and not the marathon? If top runners are cheating at 10k and then move up in distance why would they stop?
