To Run or Not to Run?!

I think I'm feeling ill. I am *considering* running a half marathon this fall. I could go either way right now.

PROS:
-force me to stay in shape/get in shape
-I set a goal to do this last spring and should follow through
-accomplish a bucket list item

CONS:

-really, do I need to say anything here!? I used the word marathon, that should be enough.
-extensive amount of time it takes to train
-I would have to run a lot.
-expensive [my main justification, because let's be honest--those other cons are just excuses]

We'll see. I mean, I should just go for it, right? Now or never! My feet hurt already.

This is what I'm considering: St Louis Rock and Roll Marathon

I'll keep you posted!
