BTC Triathlon Series

The BTC Triathlon Series takes place at Middle Head in Mosman, featuring a sprint distance course set within Middle Head Reserve. The event is open to the general public with no qualification requirements, offering a traffic-free environment for all participants. The course utilizes the natural geography of the area, including local beaches and bushland tracks.

The event consists of three distinct stages:

  • 400 m swim - a single lap course starting and finishing at Obelisk Beach.
  • 15 km bike - five laps completed on Chowder Bay Road.
  • 4 km run - a two lap course using Middle Head Road and bush tracks.

The swim portion is conducted in the sheltered waters of Obelisk Beach. The cycling segment is held on a closed road circuit, while the run course navigates through historical barracks and native bushland. Participants can access race manuals containing specific rules and course maps prior to the event.

The registration fee structure varies based on club memberships. Entry is available for members of the Balmoral Triathlon Club and Warringah Tri Club, as well as Triathlon Australia members and non-members. Photography galleries from the races are made available to athletes following the event. Visit the organization's website for the most recent information.
