Running Times for Girls. On average, girls tend to run more slowly than boys of the same age. A 12-year-old girl will fall in the top half of her peer group if she's able to complete her mile run in 11 minutes, which is more than two minutes slower than the median time of her male counterparts.unning Times for Boys. A 12-year-old boy who can complete a 1-mile run in eight minutes and 40 seconds sits at about the 50th percentile in comparison to other boys his age. Any time faster than 8:40 would be considered a good time, since it puts the boy in the top half of his age class.
