I wish I knew, too. Jeez, it's the run that kinda freaks me out in tris. One of my tribuddies is a former collegiate T&F star. He talks about how he gets into "the zone" where he feels he's just floating along, and wants to run forever. I think he's built like a human gazelle. He gets this glazed, faraway look in his eyes when he talks about it. I must stare at him in shock/disbelief/envy, because one look at my face always brings him back to reality.
