Unprepared, at best, but here goes!

I actually looked for another word on an on-line thesaurus, but things like "unrefined, unrehearsed, off the cuff, dashed off, extemporaneous" just did not seem able to replace how I am feeling about a little 20k trail run that I am undertaking tomorrow.  It is not 'unplanned' because I signed up for the Lasse Viren run four to six weeks ago.  At the time, it seemed like a good idea - and it wasn't even an impromptu, drunken decision!  I signed up when I was totally sober, maybe even on a school/work day!
But, here I am, the race is now tomorrow, and I definitely feel unprepared to run 12.4 miles of trail.
At the same time, I'm also pretty excited about the race.  It is a GORGEOUS weekend here in Southern CA, I've been slightly inspired by watching students haul butt at their cross country meet, and I know that I'll have some great views during the "race" tomorrow.  I'm hoping to get something like this:

Add to that, it will be something of a social experience since I know several people going/participating, so I can give myself points this weekend for being an extrovert! An all-around win-win situation.
Leading up to this week, I've felt a bit nervous about my knee which has a history and can be kind of tricky.  I scheduled an appointment with the knee doctor for Tuesday, hoping for the best but not totally confident that he would say, "Yes, you should keep running!".  Well, that was more or less what he said - he wants me to continue to be active (I don't know if that is so that I will continue to return to see him or if it is for my mental/physical health, but I'm not sure that it matters...).  So, based on that recent assessment, I have far more confidence in my knee, and I went out and enjoyed an short but awesome last night, a good way to top off a crazy-busy week.
So, despite my reservations about lack of training this fall, I am pretty psyched about the run tomorrow.  I have no aspirations to run fast, but I plan on enjoying it.  Hell yeah!
