Rage Against Riverhead is a timed trail run held at the big red shed within Riverhead Forest, located on the outskirts of Auckland. Participants select either an 8, 12, or 24-hour duration, aiming to complete as many 5km laps as possible before their time expires. The event accommodates solo runners or relay teams of 2, 4, or 6 individuals.
The course winds through a commercial pine forest, primarily utilizing smooth single trails and broader dirt paths, with a minimal 50-meter section of gravel road. Each lap accumulates approximately 60 meters of elevation gain, making the race challenging yet runnable. Relay teams operate with one runner on the course at a time, and the route passes the central tent area, facilitating handovers directly in front of each team's tent. Lactic Turkey Events is the organizer, with the event headquarters situated near the intersection of Barlow and Ararimu Valley Roads.
