Set amidst the serene landscapes of Bottle Lake Forest Park, the Forest Run Fest 2025 invites participants to experience the beauty of Christchurch’s coastal pine forest on Sunday, August 24, 2025. The event features four distinct race distances: the Half Marathon (21 km) known as “The Big One,” the 10 km “Middle One,” the 5.5 km “Little One,” and the 2 km “Tiny One” designed for children aged 10 and under. Each course offers a mix of terrains, including soft pine needle trails, gravel roads, and open grass sections, providing a refreshing challenge for both seasoned runners and newcomers. With a maximum of 1,200 competitors, the festival emphasizes community spirit, inclusivity, and a love for the outdoors. Participants can look forward to on-course entertainment, aid stations, and a commemorative race medal upon completion.
