Since its inception in 2014, the Chamna Chase has become an integral part of Richland’s fall running calendar, attracting hundreds of runners each year. The race supports local charities and promotes community engagement through family-friendly activities post-race. Each finisher receives awards and snacks as a token of appreciation from organizers Stephanie, Charlie, and Jason.
