Winner: Color Run

Rightfully known as the happiest 5k on the planet, the color run combines the outdoors with bursts of color. You can walk or run this easygoing marathon, which makes it perfect for friends and families alike. Many suggest wearing white for maximum color payoff, but others prefer to dress up in tutus and even animal costumes.
