Yes I am a dog and yes I am running a half marathon (13.1 miles). A couple of things about me- I am a Portuguese Water Dog. I love to run. My running partner does 10 minute miles which is like a quick walk for me. My eventual goal is to run a marathon but I am starting with a half marathon. For those of you worried about me, I stay well hydrated and as I am training I will wear dog shoes on my longer training runs.
