Running on sand is not the same as running on a treadmill, at all. For one you have the scenery. A horizon stretching out as far as your legs will take you. The sound is not bad techno music like at the gym, but the cresting waves and their hiss as they kiss the shore. The crunch of the sand under foot, and the occasional squawk of a seagull above. And when you reach your destination. When you've run as far as you can. The big blue is just waiting for you to jump in and cool off.
I don't know why I waited so long. Thank you Diana.
