Bay City’s Wilderness Run returns Saturday, with a scenic 2K and 5K course winding through Riverside Park’s hayfields, wooded trails, and camping areas before ending at the Ranger Station. The 2K starts at 9:30 a.m., and the 5K follows at 10:15 a.m. Walkers and hikers are welcome, along with strollers and leashed dogs. After crossing the finish line, participants can enjoy water, hot cocoa, fruit, and granola while cheering on others. Children under 3 can join for free but need registration to receive a shirt and medal.
