I do believe that marathon runners are trying to preserve their bodies all the race long, they never are pushing their VO2 limit. Shorter distances are probably better to use .
EPO actually provides a bigger boost in endurance than in short term performance, so Marathon should be a good case. Still even though the downward trend starts a few years late there's a limit to what conclusions can be drawn from one sport. Perhaps Marathoners started using EPO late or bad weather and tactical racing slowed them down a couple of years right after EPO was introduces. No way to be certain, but I think the overall evidence from other sports such as cycling 5 and 10K running and probably others, not to mention scientific studies, demonstrates that the advantage is significant.
