What Is the Average Mile Time for Girls?
The average mile time, or 50th percentile for girls depends on the age of the female, but varies between 10 and 11 minutes. For a 12-year-old girl, the average mile time is 11 minutes and 5 seconds. Between the ages of 10 and 14, the average girls’ mile time improves from 11 minutes and 22 seconds to 10 minutes and 6 seconds.
Male runners of the same age complete a mile run more quickly than girls, on average.
Girls running a half mile can complete the run at a time of between 55 minutes and 5 minutes, 54 seconds. These times are based upon an age range of 6 to 10 years old, with 10-year-olds averaging 5 minutes.
