Golfer Steve Alker wants to keep playing professionally until he's 60, after winning a second season-long crown on the PGA Champions Tour. 

The 53-year-old's joined the likes of greats Tom Watson and Bernhard Langer in claiming the overall title more than once. 

He's mulled over what to consider before putting the clubs away. 

He told Mike Hosking that staying fit is the biggest thing, and from there it’s about the drive. 

“If I'm just finishing 40th or 50th in the field, and not having a chance then it's probably time to hang up the boots, you know?”
