I knew at least some smart posters like Bad Wiggins would get this.
There is MUCH less benefit from EPO in the 5,000 than in the 1500. This is OBVIOUS since the oxygen demands are so much higher in the 1500. Have any of you ever heard of VO2 MAX?
This is why 1500 is probably the MOST DOPEABLE event. Just look at history. 3000 is also very dopeable.
Let me break it down for you.
100/200/400: Very dopeable. Obvious. All strength. Anabolics (steroids and HGH etc). 400 less dopeable than 200 less dopeable than 100.
800 is nearly undopeable since there is less to gain by increasing O2 carrying capacity, which simply isn't the limiting factor in elite 800 performance. Nothing to gain with anabolics, except perhaps faster training recovery but that isn't really the determining factor for 800m success.
1500/3000: very DOPEABLE with EPO. See above. See history books.
5000/10,000: much less dopeabe with EPO but this is where GREY AREA SUPPLEMENTATION comes into play, especially as distance get longer. (Hint: where did Salazar find his success?)
Overall, 800 and 5000 are the events where doping doesn't help as much, and clean athletes like David Rudisha and Ben True are likely to prevail. (Or at least have LESS of a disadvantage than they do against 1500/LD dopers.)
