Join your community for a meaningful Mother's Day 5K in Spearfish, SD, where you can run, walk, or join in from anywhere—all while celebrating motherhood and honoring those you love. If you're a bereaved mother, you can submit your child's name by April 5th to have it printed on the event t-shirt and commemorated throughout the day. Every dollar raised goes directly to Lach's Legacy, a local nonprofit working to support grieving families and fund SIDS education and research across South Dakota.
