We all know how critical the right speed is in reading a putt we think we can sink.  The speed of the putt refers not to how hard you hit the ball, but how fast it is rolling when it gets to the hole.  To be a consistent green reader, you have to be able to make that speed be the same regardless of how long the putt is.

Once you have picked out your favored speed, generally fast enough to let a missed putt roll from 12-18″ past the hole (but pick one distance, say 15″), and practice how to to make the ball approach the hole at that speed consistently.

The drill below shows you how to do that.
