Be prepared to commit. To your training schedule. To your long runs.
And to painting your toenails.
I bet you were hoping to see a giant picture of ugly runner feet today. You're welcome!
I can honestly say that, for me, this is the biggest pain in the butt about being a marathon runner. I HATE painting my toes. In fact, I'm going to have to head to the store to buy some toenail polish just to cover up these bad boys.
