Usain Bolt Learns His Lessson

Usain Bolt’s reaction time in the 200 M Heats at the 13th World Championships in Daegu was 0.314 the 2nd slowest among the 54 athletes that ran the heats. Ashmeade had the fastest 0.146.

This follows his surprise ejection for a false start in the 100 M finals. This has brought the new “no error” false start rule of the IAAF into question.

One replacement option is to charge the entire field after the first false start. The next false start disqualifies the first and the second offenders. That eliminates gamesmanship and yet allows for tight scheduling for TV.
