AM- 52º Sunny. Great temps to run in. Went down to the park a little later than I wanted too, but that is the price of piddling around. Grabbed my fuel belt and started to run and realized I was very short on fuel, but at least I had plenty of water. Miles 1-15 MP (7:39ap) and The last 5 were slow, just did not have the energy to maintain MP. I was not totally spent so I am now mentally questioning if it was just a fuel issue, fitness issue or just one of those days. Eh, I traveled all week, glad to be home, I have a busy week of work this week, but I will make the time for extra miles.
