I haven't stopped running since completing the C25K program. My goal is to run every other day and so far, I've met this goal. I've even done two runs outside (gasp!) with hills (double gasp). Of course, I can't really run up the hills yet. I try to run part of them, but my legs start screaming and I stop. I probably shouldn't stop--just work through the pain. I don't like hills. So, I'm still pressing forward, hoping to increase my speed and distance.
I feel like a need a new challenge--I think running outside is it.
