Run or Dye is making race running a little more colorful, one major city at a time. This 5K is divided up into four separate courses of varying lengths, each designated by a separate color––which also reflects the color dye the participants will be splashed in as they cross the finish line. Racers can choose to run the courses in whatever order they choose, but to move from one to the other, they'll have to cross the aptly-named Dye Zone—a polychromatic free-for-all, where fluorescent color is thrown freely from all sides, allowing runners to splash their fellow runners or get colorful revenge on their friends, family members, and any cranky art-history teachers that happen to be walking by.
Unlike some races that rank runners by time, Run or Dye only measures success in color and fun, and awards prizes accordingly. While the safe-to-eat dyes should wash out of clothing, runners are encouraged to wear things they don't mind getting dirty, preferably in white, grey, or another neutral color to allow the dyes maximum visibility.
