The most noticeable change in the U.S. Ladies Professional Golf Association (LPGA) tour, where the prize money is getting bigger and competition is intensifying, is the average distance.


"An official hosting a major golf tournament said, "It is necessary to increase the length of the Korean golf tournament to benefit long-distance players and set the course more difficultly." "Now, I aim for the green with a short iron even if I hit 230 yards. It is not at all in line with international trends, and the players do not feel the need to increase their distance by doing special physical training," he pointed out. In addition, a management official said, "In Korea, you can earn nearly 1 billion won from sponsorship costs and prize money even if you rank in the top 20 prize money rankings. For this reason, the proportion of players training severely to increase the distance has decreased a lot," he said. Another official also said, "I was surprised that there were many players who thought Korea was comfortable and had a good income, but they didn't have to go to the LPGA Tour and suffer."
