The French Open, often referred to as Roland Garros is a major tennis tournament held over two weeks between late May and early June at the Stade Roland Garros in Paris, France. Named after the French aviator Roland Garros, it is the premier clay court tennis championship event in the world and the second of four annual Grand Slam tournaments; the other three being the Australian Open, Wimbledon and the US Open. Roland Garros is the only Grand Slam event held on clay and ends the spring clay court season.
It is one of the largest events in tennis and by far the largest clay-court tournament. Because of the slow-playing surface and the five-set men's singles matches without a tiebreak in the final set, the event is widely considered to be the most physically demanding tennis tournament in the world.
