Long putts require the same technique as the short ones.
They are just longer. The same tempo and distance control are required. The object is to get your ball within the 3-foot circle. Read the break in long putts. If you miss the line, it only makes it more difficult to 2-putt. Pay special attention to the last 5 feet to determine the ball’s entry point.
Lag it close with these key points:
CHECK THE GRAIN: If down grain, expect more roll. Against the grain, expect less roll.
CUT THE PUTT IN HALF: Select an intermediate target about halfway to the hole, then aim for that spot.
TIME OF DAY: Typically, expect a faster roll in the mornings when the greens have just been cut and slower as the day progresses; as the grass grows throughout the day.
CHECK THE SLOPE: Which side is higher? Visualize the fall line. If you poured a bucket of water, where would the water flow?
WALK THE LINE: Which foot feels lower? Are you climbing Mt. Everest or descending the mountain?
LAST 5 FEET: Focus on the last 5 feet. The ball breaks most at the hole.
