This book explores the mental and cognitive demands of golf as a long-duration sport. It focuses on how golfers must maintain concentration, make strategic decisions, assess course and weather conditions, select clubs, and execute different shots throughout a typical five-hour round. The book also examines how prolonged attention and mental fatigue can affect decision-making, performance, focus, and enjoyment among both recreational and competitive golfers. Drawing on practical experience in golf club management and professional refereeing, it highlights the importance of mental endurance and sustained concentration for achieving consistent performance in golf.
