Coming back to this: assuming "exquisite" wasn't an autocorrect of "excrutiating" (running form), would you please contact Lieberman again to ask what evidence was submitted to him for this assessment to be made? Did he actually meet RY, or see his running form in real time?
Ah yes, Professor Lieberman... the world renowned Vibram rep... Err, wait... I mean: "trusted, unbiased academic"
God... so much that was spawned from "Born to Run" was exaggerated or made up...
