BTC Triathlon Series and Club Events

The BTC Triathlon Series is a sprint triathlon on a scenic Middle Head course in Mosman. The swim is in the sheltered waters of Obelisk Beach, the cycle is five laps of Chowder Bay Road, and the run uses Middle Head Road and bush tracks in Middle Head Reserve. The triathlon course is run on traffic free roads.

Course distances:

  • 400 m swim, one lap at Obelisk Beach
  • 15 km bike, five laps of Chowder Bay Road
  • 4 km run, two laps around Middle Head

The club also stages multiple time trials during the season: swim time trials at Balmoral Beach, run time trials at Balmoral Oval, and a bike time trial at Sydney Motorsport Park. Swim time trials are 1 km (two laps around the yellow cans). Run time trials are 5 km, typically eight laps around Balmoral Oval. The Jet Cycling bike time trial at Sydney Motorsport Park is 25 km with individual and team formats; entry fees differ for individual and team events.

Entry fees for the triathlon series vary by membership status. The club provides athlete guides and a race manual with course maps and rules. Transfers to another BTC race in the same season are allowed up to seven days before the event; postponement and cancellation policies are stated in the race information.
