Just prior to the turn of the 20th century, and before meetings commenced at Forest Lodge, trotting and pacing was confined primarily to match races between enthusiasts without any serious attempt at organisation.

Following some preliminary discussions, thirty-three of the sport's supporters met on 4 June 1902 at the saddlery shop of J. McGrath, a well-known harness maker of the day.

In 1911 the New South Wales Trotting Club was recognised as the controlling authority of harness racing in the state by the Colonial Secretary.

The Miracle Mile Pace was the signature race at the Glebe circuit from 1967 to 2008, originally conceived by former Harold Park Chief Executive Len Smith.

In 1966 the Tasmanian Chamfer's Star made a clean sweep of the series for driver Brian Forrester and Bankstown trainer, Max Treuer.

In 2002 Smooth Satin and trainer/driver Steve Turnbull added the race to his victories in the Miracle Mile, Ben Hur and Chariots of Fire.

Some of the winners of Inter Dominion Trotting Championship, the trotter's edition of the series at Harold Park, have included Hano Direct, Yamamoto, Diamond Field and Precocious.

While Harold Park was in its final months, the new Club Menangle circuit was constructed, being 1400 metres in circumference – ideal for mile racing.

Racing was then programmed for Tuesday afternoons and Saturday nights and the Club and complex continues to thrive in the Macarthur Region, one of Sydney's real growth areas.
