Ready to Run?

I'm not sure I'm ready to run on Saturday! This past Saturday I ran ten miles in a downpour (see photo) and my calves got so sore! I don't understand why the week before I ran 9 miles with no soreness afterward at all! Anyway, hopefully the soreness will abate in time. The other issue is that our household are coming down with colds. Oh well. The jacuzzi will feel good at least!
