I'll never forget the Carl Lewis-Mike Powell long-jump showdown at the World Championships in Tokyo (1991).
Entering the competition, Carl Lewis had been undefeated for 10 years.
In Round 1, he jumped 8,68m, a new championship record.
In Round 3, he achieved 8,83m, his personal record (wind assisted).
In Round 4, he made 8,91m, the longest competition long jump ever (wind assisted), beating the existing wind-legal record of 8,90m from 1968 by Bob Beamon.
And then, in Round 5, Mike Powel, who had so far reached 'only' an excellent 8,54m in Round 2 and was in the second position, flied with legal wind support to 8,95m, beating Beamon's 23-y-o record!
Lewis then responded with some of the best long jumps in history - 8,87m and 8,84m - and beat his personal best, but in the end finished second to a man who had never beaten him before (0-15).
Probably the best athletic race I've ever seen
