Hmm, what kind of animal? Something with a small brain? 😉
Dana, it would be great to add a 12th man but I'm thinking in another direction. It would allow us to push even harder in the earlier legs, not fade quite as much in the final leg (though I think the fading you and I experienced was largely due to the heat, not so much fatigue), and run that much faster. If we were in that kind of battle again, it probably wouldn't matter how many legs I was running. I'd end up collapsed on the ground no matter what.
As tough as it was, that last leg was pretty fun in its own way.
