To hear the gun shot at the start of the race
When an athlete "beats the gun" twice, it typically means they have false-started in a race, which is a violation of competition rules. In most track and field events, if an athlete false-starts twice, they are disqualified from the race. This rule is in place to ensure fair competition and to maintain the integrity of the start of the race.
