5K

Ran the 5K course at the reservoir this morning. It was rainy so I started off slow because I didn't warm up. I just ran easy and finished in what I thought was 30:51 as I crossed a white line that said finish, but then maybe a tenth of a mile later I saw a sign I had never seen before that said, end of 5K certified course, so I'm guessing I only ran 3 miles. My ending heart rate was 154. I was at 144 the only other time I checked about half way through.
