In Morocco when El G ran, and more recently, the key to maximizing endurance was a little bit of the special sauce.
I say that King Cheddar wouldn't be running these times if he weren't already coming from a 5k and even 10k (at least collegiately) background. Sure he can run 48 in the 400, but that's not 46. Ches isn't a Coe, Ovett, or Alan Webb. He also isn't an Asbel Kiprop, who purportedly has finished workouts in 47's on a dirt track. He's definitely no Tim Cheruiyot. He might be more of a Silas Kipligat. He's no El G, either (maybe not even El G was an El G, if we are going on guilt by association).
By the way, I'm not oblivious to the fact that El G was just encouraging the young talent. I wonder if he'll start tweeting at young Kenyans that live in Iten. They all have internet and can get on twitter, too.
