Tie-dyed T-shirts aren't just for camp crafts sessions or laid-back black-tie affairs. At the Tie-Dye Run, they're a uniform. Racers dart from the starting line in white shirts, which is then doused with a different color of non-toxic dye at each mile marker. By the time they're finished with the 5K, participants sport a rainbow of hues. It's all part of the organizers' mission to "spread the love" with the event, which is also family-friendly, non-competitive, and used to raise funds for local charities.
