What was I Thinking?

Packet picked-up, bike ready, me...not so much.  I have no idea what to expect tomorrow.  Sure, I know the trails well.  But I know them on foot, biking it will be totally different.  My goals for tomorrow 1) don't crash too hard, and 2) finish.  I had to sign a wavier that says I am properly trained for this event.   Ha, trained.  Sure, I have endurance - for running.  I have done NOTHING to prepare for a bike event.  My experience is that the muscles you use for biking are different than running muscles.    None the less, it should be fun!
