…you have to get creative. The other day I was on my usual run when I realized I didn’t want to go through the same steady motions. The strong sunshine cast sharp shadows on the side walk, and so I decided to play a game. The rule: only run inside the tree shadows. My regular straight path turned into a maze, and my steady running pace transformed into quick sprints and occasional jumps as I bound from one tree silhouette to the next. Elderly people taking a stroll giggled in amusement as I strode past them. My heart rate rose, I broke into a sweat, and I turned a good run into a great one.
