As I pinned my Pittsburgh Half Marathon bib on my Runnerâ€™s Roost singlet on Saturday night as I was tossing together my race day essentials I had a tingle of remorse. I was supposed to be proudly rocking a Pittsburgh Marathon bib that flaunted my name while stashing road race snacks in my SPIBelt. Instead, I had backed down to the half marathon at the race expo. I kept telling myself it was the right choice…I was grossly under-trained for a full marathon + I had big plans that a race day injury would really kick in the face. Plus, I knew running 13 miles with Lynne would be more fun than running 26 miles alone. I refused to feel guilty for playing it smart!
