5KColorFest, Orlando

Sprinting around with a beet-red face glistening with sweat is no way to run a 5K; it's much better to add some other colors to the mix. During the 5KColorFest, participants run, jog, or walk along a three-mile course that periodically explodes with color (courtesy of safe, non-toxic color powder made from cornstarch). After getting pelted with every color of the rainbow, racers compare their newly chromatic outfits at a post-race party complete with live DJs and dancing. All proceeds from the 5KColorFest benefit scientific research on cancer and Alzheimer's disease.
