About the race

Narrabeen Allnighter 2026 is the 19th edition of a 12 hour ultra-distance trail event held at Jamieson Park on The Esplanade in Narrabeen, NSW, adjacent to Narrabeen Lake and about 20 km north of Sydney. Competitors run repeated laps of a measured 5.275 km out-and-back loop on a bush trail that heads west from the start area, crossing a small bridge near the car park. The course is described as flat, smooth and fast, but measured trails cannot be certified for records. Entrants must carry headlamps.

The event offers divisions for Male and Female plus age-group categories, with a minimum of three competitors per age group. Race packs and bibs for 12 hour entrants are available for collection from 4 PM. Aid station details are to be advised. Refunds follow a tiered schedule: full entry less admin fees for withdrawals before Nov 1 2025; 75% less admin fees for withdrawals from Nov 1 to Nov 30 2025; and 25% less admin fees for withdrawals after Dec 1 2025 up to race day.

The event lists Tailwind Nutrition as a sponsor and maintains online race rules and event information. Visit the organization's website for the most recent information.
