Just gently redirecting you to the other thread, not knocking your opinion. Before I joined this site I spent along time weeding through threads trying to find relevant posts. I'm very exited to be discussing this stuff, even if it's just talk. Just trying to help out folks who will come to this site later to check up on Matt's attempt. One post out of 20 makes for tough research on a topic. Hope nobody feels I'm trying to steal the show, just trying to keep the discussion for the discussion, and the original point of the thread on topic. In addition, I think you're dead wrong. Despite the scale of the endeavor; personal limits and surpassing them is fairly universal. That runner who breaks a PR, the cyclist who pushes their body on a 200 mile trip, or that record breaker- little difference on a personal level, just the level that person is on when they break that limit.
