A 5K run called Run or Dye drew hundreds in Merced on Saturday, where participants were showered by multicolored cornstarch as they passed checkpoints. Organizers put the run together after receiving requests for it on Facebook. The run was meant to promote fitness, friendship and fun, organizers said. Color runs are held all around the country. Modesto held Color Me Rad in June, and The Color Run is planned in Fresno on Nov. 16.
