This week’s WordPress Weekly Photo Challenge theme is summer; for the past several that has meant chasing Usain Bolt, the world’s fastest man.

This was taken from my press seat when he returned to the track a few hours after his 100 meters world record at the 2009 World Championships in Berlin where he clocked an otherworldly 9.58 seconds. A quick breakdown of what that means more precisely: Bolt covered the distance in 41 total strides at 4.28 strides per second, his average speed was 37.6 kilometers per hour, and he reached a peak speed of just under 46 Km/H.

If you’re a fan, here’s another pic I posted of Bolt taken a year ago after a race in Ostrava, Czech Republic. All things considered, it’s my favorite shot of Bolt. A few more are on my flickr stream here.
