Blacklight Run, San Diego

Runners and walkers clad in white Blacklight Run T-shirts gather and prepare for the starting bell. Once it sounds, they take off to run a simple 5K route, but by end, they’ll hardly recognize themselves. That’s because along the way they will pass glow zones, where watchers douse them in a nontoxic neon powder that glows under the black lights and changes their clothes into artwork. Once they cross the finish line, they attend the Blacklight Run After Party, complete with DJ-spun tunes and another color throw every 15 minutes as photographers snap shots.
