The Serra Terror is a demanding team event held each year in the Grampians National Park, drawing participants to tackle two days of hiking, running, and scrambling across rugged terrain. Teams of three to eight can choose to take on the full challenge together as an Endurance Team, supporting one another through every kilometre, or opt for a Relay Team format, rotating members at checkpoints and making the event accessible to a wide range of abilities.

Each year, the course is redesigned to showcase new perspectives and landscapes within the Grampians, featuring a variety of single tracks, open four-wheel drive trails, hills, and flat sections. Distances range from 12 to 35 kilometres per day, ensuring a test of endurance, teamwork, and determination.

Whether seeking to push personal limits or share an outdoor adventure with friends or colleagues, the Serra Terror is a true celebration of camaraderie and the striking natural beauty of the region.
