Usain Bolt’s 100-meter world record of 9.58 seconds, set at the 2009 World Championships in Berlin, is widely considered the gold standard of human performance. For over 16 years, athletes like Noah Lyles and Kishane Thompson have chased the Jamaican’s shadow, but none have officially eclipsed it. However, the record books nearly had a different name at the top—if not for a massive technicality. In a bizarre 2011 exhibition, American sprinter Justin Gatlin actually clocked a time of 9.45 seconds, a full 0.13 seconds faster than Bolt’s legendary mark.
A Supercharged Sprint on Japanese TV
The performance took place on the Japanese television show Kasupe!, where Gatlin was invited to see if he could physically surpass Bolt’s speed under “optimized” conditions. To facilitate the feat, producers placed a series of high-powered wind machines behind the starting blocks and along the 100-meter straightaway. These industrial fans created a massive artificial tailwind of 25 meters per second (m/s). To put that in perspective, the wind assisting Gatlin was more than 12 times stronger than the maximum legal limit allowed for a world record.
The Physics of an “Illegal” Run
In the world of professional athletics, the World Athletics (formerly IAAF) rules are ironclad: any tailwind exceeding +2.0 m/s renders a time “wind-aided” and ineligible for record consideration. For further context, Bolt’s 9.58-second run in Berlin was achieved with a mild +0.9 m/s tailwind. Statistics suggest that a legal +2.0 m/s wind can shave roughly 0.10 to 0.12 seconds off a sprinter’s time. By subjecting Gatlin to a 25 m/s gale, the TV show essentially turned a world-class athlete into a human projectile, pushing him well beyond the natural limits of human biomechanics.
Legacy vs. Laboratory Feats
While the 9.45-second run was a fascinating display of physics, it remains a mere footnote in sporting history. Gatlin’s official personal best stands at 9.74 seconds, set in Doha in 2015—a time that ranks him as the fifth-fastest man in history. Despite the “supercharged” experiment, Bolt’s status as the fastest man alive remains unchallenged. As the 2026 season approaches, the quest for a legitimate sub-9.58 time continues, but for now, the only way to beat Bolt involves a fleet of industrial fans and a total disregard for the rulebook.
