A fast-paced, color-packed challenge that takes place in more than 50 cities in the world— this event is just as loved by photographers as it is by goofballs and racers. It’s neither a race nor a marathon and there’s very little actual running that happens (it’s not even timed). Under this year’s Tropicolor World Tour theme, the run will be decorated with palm trees and arches. Churning out relaxing island music, their slogan is “Take a 5K Vacation.” Come wearing white and get doused with a different colored powder every kilometer (those of you with sensitive eyes—wear goggles). And if tickets have sold out? Come anyways to see some rainbow-colored people.
