The Champions Tour
The Champions Tour is run by the PGA Tour and many of the best players that play the PGA Tour progress to the Champions Tour once they hit 50 years which is the starting age bracket for the Champions Tour. It is a series of golf tournaments held over the UK and USA and just as with the PGA Tour their are player rankings.
It was formally set up in 1980 under the name of Senior PGA Tour but then changed its name to The Champions Tour in 2002. today it boasts 26 tournaments and US$51.5 million in prize money. Unlike regular professional stroke play which is played out over 4 rounds the Champions Tour tournaments are usually conducted over 54 holes and due to the smaller field sizes there usually aren’t any cuts. Having said that the 5 senior majors stick to the 4 rounds.
