After nearly 5 months of injury free running, it had to happen eventually - but I wasn't expecting to be attacked by an inanimate object!
There I was, in a nice rhythm, about four minutes to go. When suddenly, out of nowhere, leapt a branch that I'm sure wasn't there mere seconds before.
I told the tree to leaf me alone and continued on my way, a little sorer than I had been when I began. I might look where i'm going next time.
