Two volunteers for the 2015 Color Run 5k Night get ready to spray color powder onto participants passing through the green section  Saturday, September 12, 2015, at the New Hampshire Motor Speedway in Loudon, New Hampshire. According to the event’s Facebook page, “The Color Run Night is a five-kilometer, un-timed paint run through the night. Thousands of participants, or ‘Color Runners,’ are doused from head to toe in different neon colors at each kilometer.” The Loudon event was one of a series of such fun runs across the country. Upcoming runs will take place in Boston Oct. 2 and Springfield Oct. 9. Goodies for Loudon participants, who helped raise money for the Speedway Children’s Charities, included headlamps and “sweet glow tattoos.”
