Good Mile Time for a 12-Year-Old

Many adults use running as part of their daily exercise to maintain weight and heart health. Of course, the popularity of running will gradually spread to children, who want to keep up with their parents. A 12-year-old can't run a mile like an adult, but if he clocks in at a higher percentage than his peers, he can expect to improve rapidly as he grows older.

boy's running time

a 12-year-old boy can finish a mile in 8:40 seconds, which is about 50th percentile compared with other boys of his age. Any time over 8:40 would be considered a good time because it would put the boy at the top of the class of his age. If the boy runs a minute faster, about seven minutes and 40 seconds, he will rise to 75%. The best mile time a 12-year-old can expect is six minutes, which will put him in the 100th percentile. On average, girls run slower than boys of the same age. If a 12-year-old girl can run a mile in 11 minutes, which is more than two minutes slower than the average time of her male counterparts, she will be in the top half of her peers. A girl needs to run a mile in 9:15 seconds to fall to the 75th percentile and reach a time that can be considered really good. As runners approached the highest percentile, the time gap between boys and girls narrowed. If a girl is 100% of her peers, she needs to run a mile in 6:22 seconds, less than half a minute slower than the best boy.

compared with adults, as children grow up and get closer to adults, you can expect a significant improvement in their mile time. For example, between the ages of 12 and 13, top male runners can increase their time by about 20 seconds. If you adjust the running time of 100% of boys according to their age, it will run a mile longer than the adult male in about 5 minutes and 14 seconds. Children's running safety for 12-year-old children running is a safe and healthy sport, but parents and coaches should pay attention not to force children to run more comfortable or train to exhaustion. If children exert too much force or wear unsuitable shoes, their knee cartilage may be damaged. Children under the age of 10 should keep on sprinting and avoid running a full mile.
