I was just thinking that Almaz Ayana is not as good as Wang Junxia from China in 1993 (which was before the first test to detect EPO in 2000).
Wang Junxia did a 15:05.78 first 5K and a 14:26.00 second 5K for a 29:31.78 WR. Her second 5K broke the 5K WR of 14:37.33, and her last 3k during the 10K race was in 8:17.47, which was more than 5 seconds faster than the WR of 8:22.62 held by Kazankina of the Soviet Union.
Then 2 days later she ran the 1500m heat in 4:01.55.
Then the next day after that, she broke the WR in the 1500m in 3:51.92, but came in 2nd to Qu Yunxia, who ran 3:50.46, which lasted as the WR until Genzebe Dibaba broke it.
The next day was the 3000m heat in 8:12.19
Then the day after that was the 3000m final in 8:06.11, which is still the WR, and equivalent to a 5000m time of around 14:03.
Renato Canova has stated that he thinks that Wang Junxia was just a great natural talent.
Renato Canova has also coached in China recently.
The women from China have never run anywhere near as fast as the women from China in the years 1993 to 2000.
