SIOUX CITY, Iowa (AP) – More than 2,500 runners in Sioux City got a blast of color as well as a workout from a 5 kilometer race. The Sioux City Journal reports runners who ran in the charity race Sunday morning were blasted with colored cornstarch at a number of spots, leaving their skin and clothing streaked with different shades. The run was a fundraiser for the Boys Club of Sioux City.

Organization board member Jim Palmer says the organization hoped to raise up to $25,000 from the race. Runner Scott Andrew, of Norfolk, Nebraska, didn’t realize he’d be sprayed with colored cornstarch but didn’t mind, saying “I didn’t know what to expect, but it was fun.”
