2.7 miles today back on the trail. It didn't feel right from the start, so I only ran one mile of it. My left hand swelled up painfully, and the only thing I can think of is that I was wearing a watch? I took it off immediately, and it's getting better. Guess I won't run with a watch anymore!
Also, the no-see-ums were CRAZY! I'm sure I inhaled several hundred. Yuk.
