About the race

The BTC Triathlon Series is a sprint triathlon conducted at Middle Head in Mosman. The swim is in the sheltered waters at Obelisk Beach, the bike uses multiple laps of Chowder Bay Road, and the run takes place on Middle Head Road and the bush tracks of Middle Head Reserve. The series is held on a traffic free course and is open to all entrants.

Course distances

BTC also runs a season program of time trials and related events. Swim time trials are 1 km held as two laps around the southern yellow cans at Balmoral Beach. Run time trials are 5 km held as eight laps around Balmoral Oval; entries are made on the day. A bike time trial is held at Sydney Motorsport Park with individual and team formats over 25 km; the team event uses a handicap system based on cumulative team age and team composition.

The club stages a Quinn Financial Planning Christmas Aquathlon at Balmoral Beach consisting of repeated swim and run laps with 150 m swim laps and 1.0 km run laps, run as a training session with an entry fee.
