From wikipedia 100 metres, October 8, 2013, ca.3:45 PM PST, but it won't last long.
Who is Matt Tiritelli, you ask? According to wikipedia, he's the fastest man on the planet. This dude ran so fast he didn't just shatter Usain Bolt's record by an entire second, he caused an anomaly in the space-time continuum that rippled all the way back to 2009 and negated Bolt's achievement altogether! Damn, that's fast.
