The question of which are the best doping performances that are beaten by Kipchoge and Bekele begs that they themselves are clean. They may well not be.
You are relying solely on performances from athletes with confirmed anti-doping violations to answer the question. That is highly selective. As has been pointed out repeatedly, known anti-doping violations are but a fraction of those estimated to be doping as most dopers are not caught. The estimates of the incidence of doping are not exact (they cannot be - they are estimates) but are of sufficient scale to suggest that no top performance can be assumed clean, and only that no violation has been thus far recorded. Former world record holder Kipsang is such a case in point.
Hence, your attempt to redefine the question according to what is "knowledge" is quite the reverse, as it assumes a definitive answer on clearly inadequate data. There is however enough wider information on doping, and in particular its practice in countries like Kenya, to say it is very possible if not likely that all top performances are the result of doping, including those of Kipchoge and Bekele.
Recall I asked one easily answerable question -- which marathon performance is the fastest known doped marathon performance, and alternatively, if there was a known doped performance faster than Luka Kanda's annulled 2:06:15.
Sorry for the lengthy response, but it becomes necessary due to the many varied attempts to avoid giving what should be a simple answerable fact, drawing from a common pool of knowledge.
It is credulous (lol) to suggest that I rely solely on confirmed violations to draw any conclusions about performances which may also be violations but are as yet unknown, or that I am attempting to redefine the question (which question exactly?). You should view this as an attempt to establish what should be common ground for everyone, regardless of beliefs -- "what is known?" I only asked one question, admittedly highly selective, out of hundreds that need to be answered to gain a richer understanding. Yet a clear answer to this simple question alone, seems to be a major challenge for everyone, as the few who did answer want to relax the criteria to "what are the best performances of performers who were caught doping at other times either in the distant past, or well after their best performance?", or even relax the criteria further to include rule violations not involving doping. Even then, relaxing the criteria, we still get only a handful of candidates running around 2:05, some three minutes now behind the fastest marathon performances. By the way, this is similar to Shobukhova and Jeptoo, the best known confirmed dopers still falling 3 minutes short of the then world record.
To address your post, this is why it would be ideal to have an accurate estimate of doped performances which are specific to fast marathons. Lacking such an estimate, we should be careful about our assumptions and conclusions (not to mention the fallacy of concluding our assumptions). The only set of figures I'm aware of for marathons, come from the Australian scientists published by the Sunday Times for blood parameters, if we accept the Sunday Times findings for blood doping prevalence as indicative, there are strong reasons to doubt the presence of doping in the vast majority of the fastest marathon performances:
- The ratio of "abnormal" blood tests for Kenyans (11%) and Ethiopians (8%) was below the average of all blood tests (12%). When you compare these "abnormal" findings to their performances, this suggests an extremely low correlation between (blood) doping and all of the athletics performances of Kenyans and Ethiopian.
While the Sunday Times did not look at fastest performances, they did look at World Championship and Olympic medals won:
- They found that only 11% of WC and Olympic medals won were won by an athlete who possessed a "suspicious" test result at any time. Using the same measure as other distance events, the marathon (11%) was about 1/5th as suspicious as the 1500m, and race-walking events (48%-54%), and 1/3rd as suspicious as the other track events: 800m, 3000m ST, 5000m, 10000m (28%-30%).
The extensive data-backed findings that Kenyans and Ethiopians were below average dopers and the marathon is by far the least suspicious distance event greatly undermines any assumption regarding the doping status of the top-100, or the top-200 fastest marathon performances.
Now I want you to take a long reflective pause before you once again falsely accuse me of concluding from these data-backed findings, that 89% of Kenyans and 92% of Ethiopions are clean, and that 89% of marathon WC and Olympic medal winners are clean. While these remain possibilities (with low-likelihood), this is neither my argument or conclusion.
The only suggestion I'm making is that we don't have enough knowledge about these 89%-92% of athletes, or about the 89% of WC and Olympic medals won. While you freely accuse me of lacking such knowledge, you seem to be extremely reluctant to admit that you, and everyone else, also lack such knowledge -- knowledge that would be necessary to form the many conclusions littered in this forum and in the press. We need much more data to be able to turn "The Gospel according to Armstronglivs" into a knowledgeable explanation of the impact of doping on the fastest distance performances.
