Bubble Bash 5k, Tempe

What happens when you combine a 5K run with a white t-shirt and thousands of bubbles? For the answer to that bewildering question, look no further than Bubble Bash 5K, a whimsical event that coats participants in a barrage of bubbles as they run toward the finish line. The noncompetitive race isn't timed, meaning there's nothing stopping you from indulging in a blast of foam at various stations throughout the course. And the fun doesn't end at the finish line; at the post-race party, participants can dance to live music. The event, which is an offshoot of The Color Dash, donates half of its proceeds to local charities.
