The concept of Run or Dye is fairly simple; as you run, walk, skip or dance your way through the 5K course, you'll get blasted with environmentally-friendly, plant-based powdered dye (aka colored corn starch) at every kilometer you reach. During the party at the finish line, emcees will count down to the final moment where everyone will "tie-dye the sky" with their own packets of pigment. The event's inspiration draws heavily from, and is arguably a bastardization of, the Hindu religious holiday Holi, a spring festival celebrating love and the changing season during which the streets become a free-for-all zone for covering each other in coats of color. This is a family-friendly event, with ages 7–12 costing $25 and children under six admitted for free. Runners are encouraged to wear white to best show off the rainbow.

9 a.m. $40 (team), $45. www.runordye.com
