One of my favorite things to do when running is to sprint at the end... As I approach my distance or speed goal, I turn on the jets. On a treadmill, I tend to jog between 4.8 and 5.4, but when I sprint, I crank up that dial well into the 7s and even sometimes the 8s. At first my body screams, there is NO way you can sustain this for a minute... but I focus. I keep my head up. I count backwards in my head from 60. I focus on my breathing. I focus on the placement of my feet. And I smile from ear-to-ear as I cross that imaginary finish line and turn the machine back down to a walk.
