When do girls peak in running?

The exact age at which girls peak in running can vary slightly depending on the individual, but research suggests that girls typically reach their peak running performance between the ages of 13 and 17. This is a time of rapid physical development and growth for girls, and many experience significant improvements in their running speed and endurance during these years. However, it's important to note that peak running performance is not solely dependent on age, and other factors such as training, genetics, and motivation also play a significant role. With proper training and support, girls can continue to improve their running performance beyond their peak years.
