As the sun goes down, blacklights begin to glow throughout the Blacklight Bubble Party 5K course, lighting the path for runners as they make their way through four bubble zones. The term "runner" is used loosely, as participants can walk or jog the course, or even opt to take the 2K shortcut. The family-friendly event is un-timed, and is accessible by wheelchair and stroller.
After crossing the finish line, all participants can partake in the after-party complete with live DJs and, of course, more bubbles and blacklights. In each city, the BBP contributes part of their proceeds to local charities and any bridge trolls who require coinage for entering the city.
