 The Macau Grand Prix is an annual motor-racing event which takes place in November.Bearing similarities with the Monaco Grand Prix circuit in Monte Carlo, the Macau circuit, known as the Guia Circuit, is a street-circuit bounded by crash barriers with almost no run-off areas.Famous for its combination of fast long straights (a Formula Three car can reach a top speed of 260 km/h at the end of this stretch ) and uphill-downhill twists, it has been known as one of the most demanding circuit in the world.
