Like Childbirth???

Today I ran 9.5K and it was a 760 kcal run! I signed myself up for a 10K run in Nanaimo on September 5th... geesh what was I thinking???   When I finished my last 10K I felt so terrible that I didn't think I would do one again, now here I am a few months later and signed up for another one.  Perhaps it is like childbirth... you kind of forget what it is like until you are going through it again! LOL we'll see.
