Recovery and Over Training

This week I had a super hilly 16 mile long run, including the biggest hill in Austin called Ladera Norte. The "Run From Hell" is aptly named.  Through this, I feel like I might be overtraining a bit.  I'm exhausted and sore.  I don't feel like I'm recovering as I should.  I took a couple of days off and caught up on rest.  It's made a HUGE difference.  I got to where I neither physically nor mentally could get into my workouts.  It was a struggle to start, really hard to get through the workout, and didn't feel like I was getting fully back to square one after the workout.  I'm feeling better now and will continue to keep an eye on this.  I need to learn to listen to my body.
