Volunteers from 1st Battalion 7th Marine Regiment throw

Volunteers from 1st Battalion 7th Marine Regiment throw colored cornstarch in a color gauntlet at the finish line of Condor Elementary School’s First Annual 5 kilometer Color Run at the Combat Center's Physical Fitness Test track, Feb. 28, 2015. Cornstarch is used as the coloring agent because it is easily cleaned up and it is biodegradable. (Official Marince Corps photo by Lance Cpl. Thomas Mudd/ Released)
