When you think about caddies in golf, most club golfers assume they are just for tour professionals. But in fact, many of the competitive women I play with in club and county events choose to use a caddie when allowed.
Certainly for the big competitions like the club championships, which is often a 36-hole strokeplay tournament played in one day, an extra pair of hands is invaluable. Your caddie can help to speed up play by raking bunkers, repairing pitch marks, keeping your clubs clean, keeping you dry under an umbrella in the rain, or even just making sure you eat and drink enough to maintain good energy levels.
