What did my left foot go and do on our 5-mile run this morning? Develop a blister on its arch. How rude! It's not a terrible one, but I can tell that it will get very sore if exacerbated, so I'm going to need to baby it this week. Silly, silly foot. It's getting to that point in the game where I've developed a healthy paranoia about injuring myself before the race. (And blisters count as injuries -- they can take you out for a long time if they get bad.)
