Bob Kennedy did run 12:58 off 95mpw, but that wasn't double Lagat's mileage AND Bob was running 3 workouts a week plus a long run AND running mileage at ~5:40...or so he said.
And Mo Farah isn't running high mileage. Salazar has said this year that Farah was running about 2/3 or Rupp's volume, and the main difference now is that he is running the same mileage much faster than before.
Less mileage faster. Hmmm, I think I heard that from another guy that's doing pretty well.
Same thing goes for Morgan Uceny at Cornell. I don't want to criticize Rojo, but how many years have we been hearing what I would call high mileage bullshit from JK? How many excuses have we heard like how hard a school Cornell is? What international results does this "genius" training have? Nothing. Morgan goes to the same school, runs 25mpw in college apparently, now up to 50 with Terrance, and she's the DL leader. That's the bottom line right there.
Unlike the negative losers around here, I see a WHOLE BUNCH of Americans who could come back from Deagu with medals (I don't mean to imply that they're all going to win medals, but I think they have a shot):
Wheating? (not tough enough, I fear, like Rupp)
Jenny Barringer (seems to be getting into contention now)
Alicia (Johnson) Montano (world leader last year)
Which of those people run high mileage?
Not a single one.
