SIOUX FALLS, S.D. (KELO) – Runners with The 437 Project traveled west on Wednesday across South Dakota ahead of the Thursday beginning of their relay journey, an eastward trek on foot from the state’s border with Wyoming to its border with Iowa. Before their caravan left Sioux Falls, runners and volunteers took a moment to reflect on why the effort takes place. The run across South Dakota is a fundraiser for the Helpline Center, which connects people to mental health resources.
