London 2012 Men's 4x100m Relay, World Record Proves Jamaica Sprinters Are Olympic Legends The 2012 Olympic Games Jamaican sprinters arrived in London with huge hopes, and they are leaving as legends. In the 4x100 relay on Saturday, the ultimate test for team speed, the Jamaicans were amazing. They exploded for a time of 36.84 and bested the world record, which they already owned, by .2 seconds. While .2 doesn't necessarily seem like it is blowing a record away, in the 4x100 it most certainly is. Luckily enough, Team USA gave us all a glimpse of just how dominant this run was as they finished second with a time 37.04, which exactly equaled the old world record.
