You may not recognize the connection to primary colors in our name. But that�s cool. Because all you really need to know about CMY5K is that it�s five kilometers of vibrant ridiculousness that will make your face hurt from perma-smile. If you�ve done a traditional 5K, you know they can be a bit bland. But CMY5K is the running equivalent of Dorothy�s house landing on the Wicked Witch. Waves of virginal white runners and walkers will start every 3-5 minutes. Then, at each kilometer, CMY5K staff and volunteers will powder participants in Color Splash Zones. Each zone dispenses a different color; 1K-cyan, 2K-magenta, 3K-yellow, 4K-green, 5K-a combination of all colors. So what if you should accidentally �taste the rainbow?� Not to worry. The powder is 100% natural and safe.
