I can’t believe Bolt didn’t reach more than 44kmh in the 2012 olympic final, but instead it’s his incredible speed and speed maintenance 0.82 three times jn a row. Bolt did reach 0.80/45kmh in 2009 in his 9.58 WR, which is mind blowing. Even having a faster last 40m split of 3.27 than Tyson Gay’s wind aided (+4.0) of 3.31
