I have and I have never been close to World Class or National Class so I shouldn't let it affect me, but when I see guy run like Bekele did, it makes me think I just need to stop running and just become your typical American fat assed sport fan. No more participation, no more "training" or worrying about PRs, reading about tempo pace, none of that crap.
It just reinforces the terrible truth that I am closer to the fat iPod wearing, camelback sporting, fuelbelt buyer than the elite super runners.
In short it makes me just want to quit.
