The 5K Foam Fest

The 5K Foam Fest – Sydney 2025 is an obstacle-course style fun run held at Saxony Rd, Horsley Park, NSW, Australia. The 5-kilometer course includes over 22 obstacles, such as the world’s largest inflatable waterslide and mud pits, all thrillingly layered in 2.5 million cubic feet of foam. The event blends athletic challenge with festival vibes—live music, a free Kids Zone for children 6 and under, food vendors, and a beer garden—creating a family-friendly, celebratory atmosphere.

Obstacles are optional, making it suitable for all abilities; participants can walk, run, or tackle elements at their own pace. Entry includes a finisher medal, foam photos, and festival access. Visit the organization's website for the most recent information.
