For the fifth annual Healthiest State Walk on Wednesday, Iowans are encouraged to “Walk at the Whistle” as the initiative teams up with the State Fire Marshal Division to coordinate fire drills and walks for businesses and schools. Organized group walks can be found online by county at the Healthiest State Iowa website, or simply get a group together to walk during lunch or a break. More than 200 walks have been organized in Polk County, and the state’s goal is to have at least one organized walk in each of the 99 counties. For more information and to find a walk, click here.
