It has been interesting that there have been no such kind of duels in long jump competition, like it was sixteen years ago in Tokyo, where Carl Lewis and Mike Powell were about to jump near the 8.9m line. Today it would mean a definite gold medal, while these years 8.4m is often enough to win the brightest medal. By the way Powell and Lewis are watching long jump final competition in Osaka right now as I write these lines.
I highly recomment to see the biography of Carl Lewis, one of the most legendary and capable light athlete in worlds history. 9 gold (!) medals from 4 olympic games and 8 gold (!) medals from world light athletics championships is just a start ;)
