Getting vaccinated. Keeping your dog at home for the race. Letting faster runners pass you on the single track trails. Loving Leadville and Colorado Mountain College. Shouting out to our sponsors: CMC, On, and every business in Lake County. Giving thanks and finding joy. Letting go. Finding yourself in the woods. Love. Education. Diversity, inclusion, and equity. Sunscreen. Cool socks. Dressing up in costumes. Drinking water. Making new friends. Dancing like a hippy at a metal show. Dancing like a metalhead at a bluegrass concert. Being grateful for life.
