2:06.07 in 2018 is 3:10 behind the WR.
3:10 behind the WR in the early 80s was either 2:11.24 or 2:11.29. I've been harsh on Rupp, but always said he was a baller. And I am impressed, but all he's done now is validate Kellogg.
And see the above that I wrote. His track times indicate a time of AT LEAST that fast. On that course, that's an expected outcome. Settle down.
In the early 80s, marathon records were being set without the best marathoners in the world.
Realistically, all early-day marathon stars should receive the same criticism that Farah gets now. Farah is running in an era of track when a huge amount of track talent from East Africa is flocking to the marathon, and ignoring track entirely. In the early 80s, East Africans had yet to even realize that they could utterly dominate the distance running scene. Once they arrived, drugs or not, it was a one-sided demonstration of how pitiful the rest of the world's marathon talent actually was.
