Thanks, jobob!

My problem is two-fold...1) I am extremely stubborn so admitting defeat and accepting a SAG ride back may never happen. 2) I'm also extremely competitive - so I am more likely to hurt myself by pushing too hard, than to admit that I'm not capable of something.

That said...my main goal is to finish. I don't care about time, I don't care about speed...I just want to finish. I'd really like to finish with enough energy to appreciate it, but if self-congratulation has to wait until the next day, I'm ok with that.
