So Mr. Fluid Kipchoge has lost only one marathon coming in 2nd to the former WR holder Wilson Kipsang. Mr. K has since been sited for whereabout doping violation. Meaning technically Fluid has never lost a marathon to anyone without a doping violation. What is it 12 marathons then undefeated REALLY? IF MR. Kipchoge doesn't lose at London or this year Olympics then after this year any lose his amass is mute...can you fathom regardless of the shoes the man has yet to lose in an era where marathoning has reached a new esclated all-time playeau.
