Justin Gatlin runs Wind Assisted 100m in 9.45 seconds

As part of a stunt for the Japanese game show Kasupe!, US sprinter Justin Gatlin recorded an unofficial time of 9.45 seconds for the 100m assisted by a wind turbine and fans.

This is well under the 9.58 seconds recorded by Usain Bolt in Berlin in 2009.

While it's not a serious record, it just goes to show how much air resistance is a factor in sprinting.
