Again, not what I wanted

7 easy miles - 70:35 - 10:00 Pace

Took the run really slow today trying to get my 8-9 miles in. Legs and lungs felt good, I just ran out of energy. That hasn't happened on a slow run shorter that 15 miles...ever. Concerning...maybe. Disaterous...not at all. I'll get a short outdoor run in Saturday and be ready to get a longer run in next week.
