True Confessions: #runchat advice!

Hi all,
Today is Tuesday, which is typically "true confessions" day.  You know, the day where you admit to eating an entire (not small) bag of pretzel M&M's or about NOT eating enough after your first 20 mile run so you crashed and felt like crap most of the rest of the day.  Yah, that day.

But, I'm not going to do that today.  Today, I'm going to confess that I'm VERY confused about how to run my 10 mile race next weekend.  Yah.  I have a race before the marathon.  A little "tune-up" 10 miler here in town.  It should be really fun and scenic, but it doesn't exactly fit into my training schedule.

I'm supposed to run 15 miles on Sunday.  Then, I have my 2nd 20 miler on Saturday.

I need some advice.

Here are my thoughts for Sunday's 10 Mile Bridge Run:

1. Just run the 10 as hard as I can - shooting for a PR.
2. Run an easy 2-3 mile warm-up on the treadmill at the gym right before the race and then run the 10 at my marathon goal pace. (Which, in all honesty, I'm also very conflicted about.  You see, I've had a couple REALLY good long 18 & 20 mile training runs, so some of my friends have put a finishing time in my head that wasn't even in the ballpark of what I was thinking.  This is another dilemma altogether.)
3. Run an easy 2-3 mile warm-up at the gym and then run the 10 miler easy.  I do have a 20 miler just 6 days later.

There you have it.  Please comment.  Take a vote.  Whatever.  I.NEED.HELP!
