Treadmill speed workout after work. This was a challenging workout! My breathing was under control and my legs felt strong. But was still struggling...not sure why or with what. Perhaps mental toughness lagging since this is one of my first hard workouts of my spring half marathon training.

6 x 0.5 at 9.0 (6:39 pace) with 0.25 rest intervals at 6.0 (10:00 pace)
0.5 mile cool down easy
all at 2% incline
