I just came back from my first real excercise session of the season. My friend and I drove to a local high school to do a series of 440s around the track with a rest period in between each. Let me just say that my legs were turning rubbery, my heart was thumping like it wanted to escape my chest, my lungs were burning with each breath, the sweat was pouring off my forehead in waves. It was almost unendurable. Then, when the ride to the track was over, it got even harder.
