Leap Frog

This is one of the simplest, and most effective, ways to train your distance control. Feel free to customize the rules as you can imagine, but as a starting point try and land each following ball where the last ball ended up. Once you reach the furthest you can hit the ball you can either work backward (land each ball shorter so it finishes rolling where the last one stopped) or start over with the shorter carry shot and ladder back up to the longer shots. Practice this for 10-15 minutes to really help improve your touch with your distance wedges.
