Professional golf tours are the means by which otherwise unconnected professional golf tournaments are organized into a regular schedule. There are separate tours for men and women; most are based in a specific geographical region, although some tours may hold tournaments in other parts of the world.
At least 95% of professional golfers make their primary income as club or teaching professionals rather than from competition. A small elite in the profession who obtain income from prize money and endorsements are called "touring professionals", "tournament golfers", or "pro golfers". The best golfers can make up to 8-figure incomes in U.S. dollars from tournament play. Including endorsement income, pro golfer Tiger Woods was the highest earning sportsman for much of the first decade of the 21st century, according to Forbes magazine.
But making a living from tournament golf can be difficult. Tournaments have entry fees and the associated costs of travel and lodging, plus the hire of a caddie. Moreover, most tournaments have a "cut" after the second of four rounds, meaning that only the top half or so continue play. Only those who make the cut receive any prize money, and only the top players take home significant winnings.
