Glo Run, Chicago

The Glo Run fun run always takes place at night, but it doesn’t seem like it. That's because the 5K course is lined with black lights and lasers, and runners sport glow-in-the-dark gear, from T-shirts to sunglasses. On-course DJs add to the festivities, blasting tunes as the untimed participants run, walk, or dance to the finish line. Even more DJs await them at the glow-in-the-dark after party, which lights up the night better than a raccoon that's swallowed a flashlight.
