I remember Elliott saying that he felt he was in the form to break Aouita's 1500WR in the form he was in when running that 1:42.97 in Madrid in May; although this quote was made in hindsight looking back on his career. I also seem to recall Walker saying something along the same lines. So, while I have no doubt the mile race was hyped as a WR attempt, I don't personally believe Elliott was capable of breaking Cram's 3:46.32 on that day, or indeed any other.
There were a fair few hyped 'record attempts' in the early 80's, usually involving Coe, Ovett, Cram or Aouita, and it was clear that in reality, this was just the promoters trying to whip up interest and spectator numbers. Some of course were legitimate, and a lot of this expectation was due to the many WR's set in 79 - 81 by Coe and Ovett, and then by Cram & Aouita in 85-87.
The thing about Elliott was that he aimed to peak in the Jan/Feb 1990 for the Commonwealth Games, and then managed to maintain that form as far as May and that 1:42.97 800m. I think I'm right in saying that he ran a world indoor record (3:34.20 for 1500m) in between. That was a mistake, as he then ran out of steam and became susceptible to injury by trying to keep his peak going throughout the European summer too.
I think that the 1:42.9 represented his absolute limit at 800m, as his official 400pb was only 48.2, although I believe he ran a 47 and bits in training. I also don't think his 1500 and mile potential went below 3:31.0 and 3:48.0, which while close to the WR's , were still a couple of seconds off.
While it is interesting to debate groups like 'non Africans', now that we are in an era where the Africans dominate, I think there are too many posts lately which veer towards being political. My own opinion, from a purely athletic/physiological point of view, is that Africans have a genetic advantage in the sprints and distance events. That is not to say that Europeans or those with Western/white heritage cannot compete with them, but they are fewer in terms of a percentage of the population.
I think that the area where there is less genetic advantage either way, are in the middle distances; 800m - 3000m.
I think it's an open playing field in these events, and during any era the most dominant athlete/s are as likely to be of European descent as African.
However, in the last 25 years or so, there has undoubtedly, in my opinion, been less transparent and robust testing of athletes from African nations than those in Europe/ the Americas, etc, for whatever reasons. I think that it is getting better and moving towards a level playing field, but I believe that more African athletes benefited from EPO use, especially in the late 90's, because of the lack of testing and the (predominantly white) doctors/coaches that saw a way of making a lot of money out of abusing this loop hole. There is also no doubt that athletes in Europe and the Americas were undergoing far more rigid and transparent testing for decades. Having said that, one of the worst nations for corruption of testing is white Russia, so all posters need to be careful when comparing athletes from different backgrounds and heritages, and not making generalisations that may be construed by other posters as being 'racist'.
I think that many posters are very frustrated that testing was not universally administered for many years, and the possible result of this was to deter many young athletes from continuing in a sport (and often going to other sports, like football) where they knew they simply could not compete. There has been rampant age cheating and limited drug testing in some countries for many years, and regardless of just how extensive that was/is, the perception from those in countries where there is no possibility to age cheat and where testing is thorough, will obviously be one of frustration and disdain. Over a period like 25 years, the 'myth' has emerged that white athletes cannot compete with black Africans in middle and distance events.
I think the IAAF under Coe is starting to get on top of things by having independent testers and making all countries compliant to equal random testing.
I hope many posters on this thread need to take a step back and chill. I think there are a lot of passionate posters whose comments are often taken out of context.
