Color Run. Have you ever done one? Their slogan is "The happiest 5k on the planet" but a more appropriate slogan would be "The most photographed 5k on the planet".
There's not much to say about this, other than you run a 5k (or walk. Like most people did). You get color thrown at you. You throw color at other people. You take pictures of all the color throwing business. It's fun.
