Harness racing became a popular sport as few people could afford the expense of a hack, let alone a Thoroughbred racehorse, whereas most families had a horse which could be driven as well as ridden. Initially trotting events were scheduled for "Trotting under saddle" and "Hack trots". Various allowances were made for horses measuring under 15 hands 1 inch, too. In 1893 hopples were used for the first time in a race at a Kensington, New South Wales meeting on the imported gelding, Plain Bill. Early in the twentieth century races for trotters drawing light carts or high two-wheeled sulkies were introduced and later specially designed light, smaller wheeled gigs were used.
