@Crankin, I think what she meant is just to make a list of the pros and cons of running, for you; take a hard look at what you're getting from it vs. what it seems to take out of you, to help you decide whether you want to continue pushing at it. Sounds like a good idea to me.
I was feeling just super sore and tired today - partly from the last couple of days, partly I'm not sure why - so I gave the hypothetical magic 8-ball a shake for the first time in a while. It said to do the 9-mile loop that's the flattest run I get from home (something like 500 feet of climbing, give or take). It felt surprisingly good, right at a 10 minute pace. It was a perfect day for running, 70° and very dry.
I'll do the hilly 13 next week instead, and then start my taper - although it's hard for me to get excited about this half, I do have a time goal in mind.
