Did a 6 mile out and back today and then decided that I should cool down a mile afterwards. Cutting down on the way back was ROUGH, but I eventually got into a grove. Last three splits were 7:18, 7:01, 6:44. I felt like acclimating to the faster pace was a little hard, but I didn't feel super fatigued and this showed when I checked my heart rate during those last few miles. While I wish I could have gotten more out of this workout, I'm just going to be optimistic and confident that the predator run should go way better for me than it has in the past.
