The date was August 28, 2011. The setting was the biennial world-championship of track and field, held on this occasion in Daegu, South Korea. The “world’s fastest man,” Jamaica’s Usain Bolt was expected to easily defend his 100-meter crown that he won in 2009 after also taking the Olympic gold in 2008. Two of his main competitors were not even in the race. Jamaican teammate Asafa Powell withdrew right before the event with a groin injury and American rival Tyson Gay was out of commission with a hip injury. Bolt had cruised through the preliminary heats, and it seemed like a gold medal was a forgone conclusion, but something very unexpected happened. After getting set in the starting block, Bolt jumped the gun! He was disqualified by the very controversial new “zero-tolerance” false start rule that had been enacted the previous year. Under the new rule, there were no second chances! A single false start now disqualified a runner. Therefore, there was now no chance that Bolt would repeat as world champion in the 100 meters because everyone knows that you can’t win the race if you aren’t able to start the race! Similarly, you can’t win the race if you can’t “get out of the blocks” (due to injury, cramping, or whatever). Either way, whether as a result of inability or disqualification, the failure to get started down the track makes it impossible to even finish the race, much less win the race! On this occasion it mattered not that Bolt was the world’s fastest man because there was now a 0% probability that he would win the race.
