Not in the half marathon club (yet?

) but congrats to all of you working so hard!
I'm bummed. I did 1.5 around the neighborhood this morning, and my lower back is still sore. I know it's because of my kidney stone surgery, but trying to figure out if it's because of the procedure itself (internal swelling) or if it's because I'm still passing stone fragments (sorry for the TMI) which means I could run through it. I see my doc on Tuesday morning for my post-op, so I'll ask then. In the meantime, I'm still running slooooow and easy.
Joyful - I'm curious, why 5.4 miles precisely? Have something against 5.3 miles, or 5.5?
I have a run scheduled tomorrow morning with a work friend. I got her into the c25k and tomorrow she's supposed to do 2 miles. It's my first time running with someone! Should be interesting.
