Event Overview
The Narrabeen Allnighter is a 12-hour run where the goal is to cover as much distance as possible within the time limit. It also offers a marathon starting at 10:00pm and a 12-hour teams event for pairs. The event uses a 5.275km out-and-back loop near Narrabeen Lake, around 20km north of Sydney. The 2026 edition is scheduled for Dec 12/13, with the start area near Jamieson Park, Narrabeen.
What the Course Demands
This event is built around repeated laps on a measured 5.275km out-and-back loop, so pacing control and efficient lap rhythm matter across many turns and turnarounds. The course is described as flat, smooth and fast, supporting steady effort, but the 12-hour format rewards consistency and good management of stops at the start-area aid station. For the 12-hour, results are recorded by completed half-laps with a countback if tied.
Who This Event Suits Best
It suits runners who prefer an ultra-style time format with frequent access to support, including those aiming to practise sustained, even running rather than chasing a fixed finish time. The marathon option fits runners comfortable with a late start and repeated loops. The 2-person teams race works well for athletes who want shared workload and structured changeovers at the end of full laps.
