I had a nice workout this morning. My program had a more manageable run time; 5 min warmup walk, 25 min run, 5 min walk, 15 min run, 5 min cooldown walk, so only 40 min running. To my surprise, I ran the 40 minutes easily! It was one of those awesome runs where I felt good the entire way. I was careful to keep my jogging speed a bit slower so I had the energy for the entire run, maybe that's what did it. I wasn't completely exhausted by the end of the run; I felt great
