Abs of Steel?? Or Legs of Lead!!!!

Definitely legs of lead today. I was pretty tired after a long week...unfortunately my schedule for the weekend looks to be even longer! Did a 1hr 30minute run today outside. It was a nice evening, very cool but not uncomfortable. Felt pretty sluggish for the first 45 minutes or so, but then got my legs under me and felt better for the second half of the run. Goal today was to keep heart rate down and clock the middle 5 miles of the run. I did manage to clock 2 miles of the run but my heart rate was jacked all day.
