Ok...Considering that I said, "I know this is using Hall's contested marathon time" which was still equivalent to a 2:06ish marathon on another course, and "I think this is one of the best examples" meaning it is my opinion and there may be better examples, demonstrates to me you should read something before immediately dismissing it. As far as Geb goes, he never ran a marathon and a race shorter than a 10000m road run in the same year according to his IAAF profile, so Ryan Hall's road mile is still the best example I can think of demonstrating how marathon fitness does not translate to mile success.
I did read it before immediately dismissing it. I explained to you why I disagreed. You sound like an idiot. Ryan Hall should not be used as an example at all because he is way too inconsistent. He couldn't even break 30 min for a 10k not too long ago.
