Yes, he did.
Off the top of my head, he dnf a 1500 in 2009, then ran 12:56 3 weeks later.
And you must be a troll I'm guessing? And your response will be: "no, I am not."
1 DNF in 2009
You know, the year he went 6/6 for the Golden League?
This is incredibly rare for Bekele, you need more examples as the past few years have all but been amazing for him, double gold in Beijing and again at the world championships in 2009 along with a golden league title.
You guys are expecting more out of the man? The only person more decorated than him at the olympics are swimmers.
