Lamington Classic Trail Run
The Lamington Classic is a trail running event established in 1970 and described as Australia’s oldest trail race. It runs along the Border Track through parts of the World Heritage listed rainforest in Lamington National Park, between Binna Burra and Green Mountain (O'Reilly's).
Saturday offers two format options and Sunday features the one-way crossing back along the same route. Distances have been measured with a steel wheel and a one-way crossing is 21.3 km; the 42.195 km option starts slightly into the forest to reach the official marathon distance.
Key participant requirements and logistics include:
- 21.3 km one-way crossing
- 42.195 km double crossing (Saturday)
Competitors must carry mandatory gear and meet entry requirements for longer distances. Marathon entrants must show prior qualifying experience in a "Hostile" trail race of 30 km or longer, complete a compulsory stop at the O'Reilly's turnaround, carry at least 1 litre of fluid at the start, and carry a compression bandage. Half-distance entrants must carry at least 600 ml of fluid and have completed a road 21.1 km race.
The course is a Class 4 walking track with exposed roots, rocks, muddy sections and creek crossings; ankle-supporting footwear and basic navigation and self-rescue preparedness are recommended. Water is provided only at the two ends of the course; there are no formal mid-course drink stations. Event logistics cover transport of overnight gear and limited parking at Green Mountain.
