Roadtrip - congratulations on the 4.5 miles, that was a great beginning even if it didn't feel like it. I hear you about the hills - the definition of a "hill" is at least partially subjective and related as much to to what we are used to/conditioned for as the actual topology.

I think you did great, and you did what you needed to do for your body. The important thing is you listened to what you body was telling you - which makes you a wise woman!
