Average drives according to a survey by Frank Thomas, former technical director of the U.S.Golf Association.
The average drive of a 90s-shooting male golfer is 192 yards. He thinks he hits the ball 30 yards farther than that, according to a survey of more than 18,000 golfers completed three years ago by Frank Thomas, the former technical director for the U.S. Golf Association. In fact, the survey found that 41% of men estimate they hit their drives 250-plus yards, which hard data from club manufacturers expose as total balderdash; in reality, maybe only one in 50 golfers routinely hits drives 250 yards. Senior men are lucky to coax 170 to 180 yards out of their tee shots. Typical female golfers drive about 135 yards.
