The French Open, often referred to as Roland Garros (French: Les internationaux de France de Roland-Garros or Tournoi de Roland-Garros, named after the famous French aviator Roland Garros, is a major tennis tournament held over two weeks between late May and early June in Paris, France, at the Stade Roland Garros. It is the premier clay court tennis tournament in the world and the second of the four annual Grand Slam tournaments the other three are the Australian Open, US Open and Wimbledon. Roland Garros is the only Grand Slam 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.
