FootGolf is a combination of the popular sports of soccer and golf. The game is played with a regulation #5 soccer ball at a golf course facility on shortened holes with 21-inch diameter cups. The rules largely correspond to the rules of golf.
FootGolf as a game is played throughout the world in many different forms, but as a sport it is regulated by the Federation for International FootGolf (FIFG). The American FootGolf League (AFGL) is the exclusive member of the FIFG and governing body for the sport of FootGolf in the United States. The AFGL is organizing tournaments throughout the US and working with golf courses to bring FootGolf to their clubs as another avenue for revenue and to develop the game further.
