The thing about Isiah or even Alamirew is they may be a flash in the pan. I remember Isaac Songkok ran that 12:48 or 12:49 some years ago and he hasnt come near it since so that maybe the case with this kid. Even if he did break the wr, to have the career like Bekele or Gebrselassie is very rare.
On another note it is interesting that Kipchoge has ran 1255 all these years later, it seems coming close or bettering his 1252 he ran at such a young age. He seems in great form this year. Kipchoge is one of the few to have a long, great career. It's also nice see Augustine Choge running well. Love to see him run a 5,000. Be well all!
