extreme running

I seem to have deleted my post somehow so here goes attempt 2.
Normally this wouldn't be extreme running. Normally someone would not take on a 15K with out properly preparing. Well there is nothing normal about attempting this 15K tomorrow. I have done 2 long runs, one 6 miler in November and one 8 miler this past Monday. That is not good. I haven't been running more than 1-2 times a week and I haven't seen the inside of the gym in the past 2 months. Wow what happened?!?!
I attempted the 8 miler on Monday because I wanted to see how bad I would feel and how bad of a job I would do on Saturday. Well the happy news is I can complete it. The not so happy news is I will have to run it anywhere from a 10:30 to 11 min/mile pace and I will be hurting afterwards for about a day. I recovered well so I'm not too worried about the pain. I know I could have done it so much better, meaning at a better pace but it will have to do.
My goal after this run will be to get back into a routine. I want to train for a half marathon with Goober. I want to push her mileage-wise but the good thing about it will be that I can take it easy speed-wise. I have to come up with a plan ASAP so that come Monday I am on a plan and no slacking this time!!!
Wish me luck.
