What Have I Gotten Myself Into?

So, for some reason or another, I signed up for a half-marathon. I knew it would be tough, having already run an 8-k a couple of years ago and wanting to die before I was finished, but my friend is running, too, and I am in better shape now, so I guess I deluded myself into thinking it would be fun. I have been "training" for a few weeks now, but decided I should look up an official training schedule just to make sure I was on track. At this point, according to the schedule, I should be running approximately 3-4 miles a few times a week with a big, long run on the weekends. I wasn't exactly sure how far I had been running, since I had mostly been focusing on increasing the length of time I could run, so this morning I decided to try 4 miles. Keep in mind, a half-marathon is 13.1 miles, okay. 45 minutes later I FINALLY get to 4 miles. Yikes! For those of you familiar with SLC, let me tell you about the course: it goes from the U of U, along Foothill to 21st South and then down to 7th East, and over to Gateway. **GULP** What have I done? This is going to kick my keister. But I am determined to do it, so I figure if I blog about it, and everyone knows I am doing this, it will help motivate me even more. I hope, I hope!
