Thanks for considering my points. Here’s my response to yours.
1 and 2. Yes, he may just be better suited to the marathon than he was for the track, but to be that much better in his late 30s than he ever was in his 20s, and also be so much better than any other marathoner in history at his age, still raises eyebrows. 2:01:09 six weeks before turning 38 (and very possibly even older) is incredible.
3. He was not the world record holder at the 2016 Olympics. He needed super shoes to break the record. That said, what others might have done in that situation isn’t germane to this discussion. The point is he took the opportunity to gain an unfair advantage over his competitors. Given that he took that opportunity, it’s plausible that he would take others.
4. You’re correct, association doesn’t prove guilt. But it sure does make it more probable.
5. Being a marathoner doesn’t mean you can’t race more than twice a year. Lots of marathoners mix in a half-marathon, 10-miler, 25K, etc as part of their schedule. But that’s beside the point. The point is racing only twice a year gives him a lot of time to dope in between competitions.
6. Yes, we all know his 1:59 attempts were not record eligible. Again, that’s not the point. The point is those efforts were a scientific experiment, and it’s plausible that wind resistance was not the only variable being manipulated as part of that experiment.
7. I never said Nike was covering up all their athletes. I’m specifically referring to their partnership with the man who is the face of the benefits of their super shoe tech. It’s not that much of a stretch to think they could be working with Kenyan officials to ensure Kipchoge never gets popped. Corruption in Sub-Saharan Africa is well-documented:
I’ll close by noting that, as you’ve done, you can try to explain away some of my individual points, but if we look at them in their totality, it seems that it’s more likely than not that he is doping.
