Find a flattish practice space and place a tee 10 feet away, and another a further 40 feet away.
Take your first putt and get it just past the 10-foot tee. Your next putt must go beyond the first putt. Your third putt beyond your second putt, and so on until you hit it past the 50-foot tee, or leave it short of your target distance.
How many can you manage? Practice and see what record you can set. Find some friends and make it a Friday evening fun event.
Come and have your setup and alignment checked your stroke assessed and your Putter evaluated for fitting. Become a better putter.
