I think what others said is correct - they are so very much more aerobically fit than high schoolers. And they are doing this as their job, so people are watching, media is watching, so they won't show their tiredness. Good example that they are tired is Kemboi after WC 2009, as has been said.

Dont forget his thick and very oxygen rich blood...
