Any loyal letsrun fan has read at least part of the nikefreeme thread. I know there is speculation who he was, if he was real or not. I've read some people have speculated it was Trent Hoerr. Here is something to add in why it could be.
I went to the Univ. of Illinois XC camp in high school in the summer of 2007, and I recently was looking at the packet of information/lectures I brought home. Wendel McRaven gave a lecture on cross country base training. Near the end he brings up "How to build endurance? INCREASE YOUR MILEAGE!" Next Slide-"How much? I don't know! "Experiment of One" This slide has a picture of Trent Hoerr running. He also has sample patterns up to 100mpw for high schoolers so I wouldn't be surprised if he let his college runner go much higher than that. Those are my thoughts.
