In another thread, regarding Seb Coe saying the a rubberized track would give a runner 1.5 seconds per lap advantage over a dirt track, I pointed out that when Kip Keino beat Jim Ryun at the 1968 Olympics, he not only had an altitude advantage, but also possibly unfair team tactics. I thought others might be interested in this subject, too. Here is a link regarding Skah of Morocco and Chelimo of Kenya, which is interesting in and of itself. However, the part I want to point you to is at the 2:05 mark, where Keino's and his teammate Jipcho worked together to beat Ryun. Jipcho himself admits that it was unfair, that Ryun would probably have won the gold (despite the altitude disadvantage), and that it was planned beforehand. None of this takes anything away from the greatness of Keino or Ryun. It's just something that a lot of people don't know, and this might dispel some of the ignorance out there. I think everyone will find this interesting. You can watch the whole thing, of course, but pay particular attention beginning at the 2:05 mark.
