Every run is different. You either have awesome ones, in between ones, or just flat out terrible ones. Tonight's was bad. It was difficult to stay focused. I'm thinking that a lot of it has to do with the time change (haven't slept well the last few nights) and that I haven't had a lot to eat today. My energy was low and my mind was everywhere.
The main thing is though that I pushed through it all and accomplished today's goal. 3 miles = check!
