Warrior Dash Regret

I am having Warrior Dash Regret.  Why did I sign up for this scary race?  It is only 87 days away.  I will NOT be ready!  Yikes!  What was I thinking?  I will not be physically strong enough to do these obstacles.  I am not even sure if I will be able to run the distance at that point...let alone pulling myself over walls and crawling through mud.  Two of my friends are doing it with me, but will I embarrass them by not being ready?  Will I embarrass myself?  Will the other people who are doing it look at me and ask themselves, "What in the world is she doing?!?!?"  Will I be the butt of jokes or worse yet...the charity case...oh, that poor fat girl...will they pity me?!?!?!?!  I am not dropping out.  I can't.  I refuse.  I will have to train more and prepare myself for it.  Can I do this?  Pray for me!
