What age do marathon runners decline? The Science Behind Age and Performance
According to research, highly trained marathon runners can expect a gradual performance decline of 0.5 to 1 percent per year starting around age 35, a process that accelerates after 60. While age-related slowdowns are inevitable, a strategic approach to training and recovery can significantly mitigate this decline for runners of all levels. Understanding the physiological changes behind this shift is key to extending one's running career.
