Darned Ankle Sprain

I went out to the park alone this afternoon to run the 7-mile loop in the cold rain. At 3.5 miles, I stepped in a hole of some sort and sprained my left ankle. It was my first ankle sprain in 16 years of trail running. I did a combination of running and walking the last 3.5 miles. I have been treating it since. The swelling is not too bad, but it is painful to walk on. I will do short runs for a couple days and hopefully it will be okay for the 50K on Saturday.
