Lag putting “Gate Drill”

I set this up from 20, 30, 40 & 50 feet!

Putting to a gate made with two tees approximately 6” wide and 24” from the fringe!
The ball must go through the gate but not hit the fringe.

Basically putt from the middle of the green to gates set up for uphill, downhill, left to right and right to left!

In order to back up from 20 feet to 30 feet the player must get 3 of 5 putts through the gate but not hit fringe and then back up 10 feet to next distance!
