Ruth Chepngetich's performance is concerning

You aren't genuinely asking that question are you? The answer has been out there for decades.

So she’s either the best long distance runner of all time or the biggest fraud. My money is on the second option. Shaving 4 minutes off of your PB in one race after running the marathon for over half a decade to go sub 2:10…..year sure. Kenyans yet again making a mockery of the sport.

Those time equivalents are irrelevant and there are plenty of Japanese male 14 minutes and 29 minutes performers who run 207 to 209 in the marathon. The Japanese performers are universally considered clean, so if Chepngetich has similar credentials at 5/10k, then her marathon performance should not necessarily be considered as the product of illicit preparation and usage of prohibited products.

I wonder, just how long have they all been cheating? Was Kip Keino on something back in the 60s? They didn’t have the drugs they do now, but there was probably something. It looks like the East Africans have never really had any genetic advantages and have just been able to get away with doping for all these decades.

The performance definitely raises eye brows but come on, those equivalences are pure garbage at the shorter distances.
