The Experience

Join us Labor Day weekend for the Calarat Challenge Trail Running Festival. We start the festivities off on Saturday night with a 5K that you can run, walk or hike, and our Kids 1K. Then on Sunday morning, we have the 1/2 MARATHON and 10K. All trail races start and finish at the Cal-Wood Education Center, and are run on a number of different trails throughout the beautiful private properties of Cal-Wood and Balarat Outdoor Education Center. Cal-Wood Education Center is a 501(c)(3) non-profit organization dedicated to providing unique outdoor education experiences that inspire a greater appreciation for the natural world. They aim to offer enriching environmental education programs that foster a sense of wonder, responsibility, and stewardship in students of all ages, with a particular focus on including underrepresented and low-income communities. Since their inception, Cal-Wood has been a beacon of hands-on learning and environmental advocacy. They proudly offer programs that immerse participants in the wonders of nature, from their summer camps to their year-round educational field trips, family camps, and workshops. Their dedicated team of educators work tirelessly to cultivate a deep connection between our visitors and the environment. We have lodging or camping on Saturday night, as well as a great pasta dinner prepared. After the race, celebrate your accomplishment with your family, friends, and fellow participants at our after race party.
