Macau Jockey Club was formerly the Macau Trotting Club. In 1989, the Trotting Club changed ownership and was transformed into the present Macau Jockey Club for flat-racing. The first race was held on 10 September 1989. In 1991, the Macau Jockey Club was acquired by a consortium led by Dr Stanley Ho. The Board of Directors appoints a Chief Executive to handle the daily administration and management of the Club while the Management Committee composed of members of the Board of Directors is responsible for major policy-making.
The Macau Jockey Club is one of the largest private employers of Macau with around 1,000 employees (of which about 500 are stable hands) and over 600 part-timers.
The Macau Jockey Club has races all year round. Racing Season starts in September and ends at the end of August in the following year. Basically, there are two racemeetings per week, night meeting on Fridays and day meeting or twilight meeting on weekends.
