About the race

The SquareOne Women’s BTC Triathlon is a women-only, non-competitive short-course triathlon held at Middle Head in Mosman. The event is described as an enticer distance triathlon and is open to female participants aged 15 years and over. The course comprises a 200 m swim in the sheltered waters of Obelisk Beach, a 9 km cycle that uses three laps of Chowder Bay Road closed to traffic for the race, and a 2 km run on Middle Head Oval.

Entries are available for individuals or relay teams. Team configurations may include one person completing all three legs, two people splitting the legs, or three people each completing a single leg. Swim aids and wetsuits are permitted for the swim leg, and any type of bike is allowed except e-bikes. Entry fees listed in the event material are $20 for an individual and $40 for a team; individual entries include a Triathlon Australia Day Pass for race insurance. The event is conducted in accordance with NSW Triathlon rules.

In the lead-up to the race, the club offers free training clinics and a free, downloadable five week training programme. Club training sessions take place from the club house at Balmoral Beach, opposite Balmoral Baths, with regular run, bike/run, and open water swim sessions scheduled in the weeks before the event, plus a small number of special sessions.
