Runners attempt to run on treadmill at world record pace

A treadmill has been doing the rounds at various major World Marathon Races following Kipchoge’s World Record time of 2:01:39.  A nice test to see how long you could run at his speed (13 mph/21 kmph) before falling off the treadmill.Watch the video here courtesy of Runners World.To put his record into context he ran roughly the equivalent of eight 14-minute Park-runs back to back!
