Chamna Chase

Chamna Chase is a small trail-and-road race at Chamna Natural Preserve in Richland, Washington, offering 6K, 10K, and half marathon distances, plus a short kids loop. Held near Halloween, costumes are strongly encouraged, allowing for a mix of seasonal attire and casual preserve runners. The field is small, typically between 1-100 participants, with fees that are budget-friendly for a multi-distance event. The courses prioritize dirt trails, incorporating occasional rocky sections and some pavement on the 10K and half marathon routes. The half marathon features out-and-back segments with a central loop, while the 10K covers the initial out-and-back and loop. The 6K is primarily a single large loop. Dogs are permitted if leashed or at heel, and finishers receive Chamna Chase pint glasses. Post-race, participants can enjoy snacks, awards, sponsor prizes, and costume prizes.
