We were thrilled to host the 40th Annual Spearfish Canyon Half Marathon & 5K on July 11, 2026. We made history, with a record-breaking 748 registered participants from 37 states and 4 countries.
Since 1986, your support of this signature event has helped Northern Hills Area CASA continue its mission—ensuring every child has a powerful voice by their side. This race serves as a fundraiser for Northern Hills Area CASA, a nonprofit organization dedicated to promoting and protecting the best interests of abused and neglected children across eight counties in western South Dakota. We are deeply grateful for your continued support.
Online registration for next year's event will open in January. Save the date for Saturday, July 10, 2027. Join us and run/walk for the CASA Cause.
