Rating My Runs

I've been using an app on my iPhone that tracks my running progress in the Couch-to-5K program.  At the end of each run, I log my distance, speed, and overall feeling about the run.  The app uses a 5 point rating scale, similar (but not exactly) to the one below.

At the completion of each run, I reflect upon how I felt throughout the course of the run.  I take into account, my speed, distance, strength/weakness, pain (or lack thereof, hopefully) and general feeling about how I did.  I think rating myself will be important as I progress in my new running life!
