The Firefly Run combines the rigor of a 5K and a 10K race with the kaleidoscopic colors of a light show. LED beams and lasers pierce the dark, leading racers decked out in light-festooned gear through nighttime streets and parks to raise money for charity. Race coordinators keep competitors bright by encouraging them to wear costumes fitted with glow sticks, cartoonish helmets, light-up armbands, or any other light-themed decoration. Beyond the finish line, runners and audiences alike celebrate at a postrace dance party with live entertainment, visual effects, and a costume contest that rewards unique outfits and the athlete who was able to ward off the most gremlins.
