Course record on the 100mi Western States race. He can do longer than 50 miles, and does it well. In this sense Kipchoge is a failure. He wanted to break 2 hours and didn't. He's a failure and no matter what he does, or how many WRs he has and marathon majors he wins, he is still a failure. We saw it in London, he failed. We saw in Berlin, he failed. Such a waste of talent when all he does is fail.
