Bubble Run, Miami

With its black lights, neon colors, dance music, and hundreds of people frolicking through foam, the Foam Glow afterparty looks a lot like an outdoor music festival. Except, unlike at a typical music festival, the crowds of partiers had to run a 5K to get there.

The Foam Glow 5K requires runners to don all-white clothing and navigate various Foam Glow zones, where they get doused with 100% natural, non-toxic foam. Each zone sprays orange, pink, or blue foam, which glows in the dark under the course's high-intensity black lights. By the end of the race, the runners' crisp whites are transformed into tie-dye creations. Once they've crossed the finish line, participants head to the afterparty, where DJs, food, drinks, and more bursts of flourescent foam await.
