Colorado miler, what I say is that for me is not something impossible to run 3'26" with the talent of El Guerrouj and with his professionalism (which, I repeat, is very much superior to the professionalism of best Kenyan athletes).
About your doubts, I disagree, for the following reasons :
a) the fact he was able to last at the top for so long time, having also during every season a great continuity, in my opinion can confirm an athlete is clean, not an athlete is doped. With doping, it's possible to have a peak lasting only for a very short period, because, if you compete frequently, and of course you need to stop using doping for not becoming positive, you go, step by step, to lose the doping benefits (in 1500m more evident than in long distances), and your shape decreases.
In the case of EG, he had many seasons with WR at the end of them, and great continuity during several months, showing a balance in his performances that are not the same way showed by doped athletes (look, for example, the development of the seasons of Boulami, Ramzi or Kaouch).
b) if you know Maroccan athletics, you need to know there were different clans, based not only about economical factors, but also about different vision of training (including in this vision also the vision of doping).
For example, Jaouad Gharib is an athlete completely clean, and was Always separated by the other Marathon runners, because his training was much more consistant than the training of the other best specialists. He preferred to create a great aerobic capacity running high volume of km at high intensity, Others preferred to use some illegal help with less mileage.
El Guerrouj was one using high mileage and great continuity in training, and practically never had any injury.
I can have doubts about athletes able to do workouts of very high lactic intensity with little aerobic support, because in this case the support comes from some doping.
But El Guerrouj never was part of this category.
c) I don't understand your point about 800m. What does it mean "you don run 800 for hiding doping" ? So, if you are doped, you can run the WR of 1500m without being tested positive, but if you run 800m you are positive ?
d) Why he retired ? Because, after winning 2 gold medals in Olympics (which was his dream), and having all the WR, and having 30 years, and being the number 1 in 1500m from 1996 (so, 9 year of dominance), he lost motivation, having already reached ALL the goals he could reach (and the real life,when you are an athlete, has yet to begin).
Why many of you don't think that an athlete can lose the will to sacriface everything in his life (what he needs in order to be the number one for long time), and can't have instead the willand the ambition to do something else, after winning everything in his sport ?
If a top athlete has respect for his career, he has to retire when is still at the top, because to prolong the career without the same motivation can't produce the same performances of before. If you continue, can be for two different reasons only :
1. You have an incredible passion for running (for example, the case of Haile Gebrselassie), and you like to run and to compete till when you stay alive
2. You run only more for money.
And EG can't be included in any of these categories.
