The Glo Run’s 5K fun run event always takes place at night, but it doesn’t seem like it. The 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 there at the glow-in-the-dark after party, which lights up the night better than a raccoon that's swallowed a flashlight.
