Kenyan runner Eliud Kipchoge achieved an historic milestone -- becoming the first person to run sub-2 hour marathon ... EVER!!!
Kipchoge completed the monumental feat Saturday in Vienna, running a 26.2-mile path that was specifically charted for this attempt, and as such ... isn't technically viewed as a sanctioned marathon course. Because of that, this new time won't be recognized as a world record -- but still, the guy can say he did it ... clocking in at 1:59:40.
BTW, he holds the official world record for a marathon time at 2:01:39, which he set in Berlin just last year.
