3.6 Mile Run with Two Sprint Intervals Posted on July 5, 2014 by MikeW It was 88 degrees out today, and with the smell of firework gunpowder still with me, I ran gentle hills on asphalt in the hot summer sun. I put in two sprint intervals, both uphill. I loaded enough water before starting. I love our country. Happy Fourth of July!
