Overtraining?

missed my planned 4-miler on Friday, but made up for it with a 3.6 miler on Saturday. Wow did those 3.6 miles HURT. I had thought that overtraining only affected ultra athletes that did some extreme training, but I looked it up yesterday and I've got just about all the symptoms. Muscle soreness, fatigue, insomnia, headaches, irritability, got 'em. Weight loss? Nope, don't have the one symptom that might be of some use to me. I was up for a couple hours Sunday night with Princess and yesterday morning's planned 9-mile run just wasn't going to happen. I had enough trouble dragging my lazy butt out of bed and to work, forget going to the gym, it just wasn't going to happen. I know that trying a treadmill run when I felt that way has lead to tripping in the past. Maybe it's just my inherent laziness coming through after a few weeks of training. It's just so annoying, though, because two weeks ago I ran my longest run ever, 8.25 miles, and I felt great. Now with four weeks left to go until my half marathon, the thought of dragging myself across 13.1 miles is the last thing I want to do. I hope that missing yesterday's long run won't be too detrimental to training, but I have to remember that training schedules don't take into account sick kids, family obligations, work conflicts, etc. This morning I got up and even though I didn't do training of any sort yesterday, I hurt. My arms, legs and core are sore as if I had a really tough workout. I'm skipping one more day at the gym and then I hope to get something done in a workout fashion tomorrow. I really wish I had just stayed in bed.
