I'm not a good runner. I love to run and it makes me mentally and physically better, but I'm not fast and not pretty. Think about a fast-moving upright turtle - that's me.
My friend Natalie, however, is both fast and beautiful to watch. She runs like a little kid - even when pushing her kid uphill in the stroller. Anyway, Natalie can run a marathon and she generally kicks ass. Whenever I am trying to go faster or run better, I think to myself "run like Natalie". You can read Natalie's blog here.
