Children develop really quickly throughout **those 10 years**. But let's do it in a way that disregards age. The first thing you'd need to know, for example, is how long their stride is. For example, my jogging stride is around 3 feet long (1 m). Then you need to know **how many strides** per second they can take and whether or not this changed over the course of **100 meters**.

The average adult male can jog about three miles (5 km) an hour. Children's running speeds vary depending on their age, gender, body size, and fitness level. However, they can usually reach between 10-30% of this rate - which for young children is about 0.6-2.4 miles (1-3 km) per hour.

So, it takes them around 1-3 minutes to cover the distance. But again, this is assuming they are adults and have similar fitness levels as me. If they are less fit or younger than this will increase/decrease the time required.

While some children can run as quickly as many adults, no kid can ever sprint as fast as a peak-athlete adult. As youngsters grow into adolescents, you may see significant improvements. By the time kids reach adulthood, they should be able to walk or run 10 kilometers (6 miles) without excessive fatigue.

During childhood and adolescence, bones continue to develop and mature, so kids' legs are always going to be thinner than adults' legs. The average weight of children is 50 to 55 pounds (22 to 24 kg), while adults usually weigh 180 to 200 pounds (82 to 90 kg). This means that children can move more mass in their bodies per unit of **body size** than adults can. This also means that children's muscles must work harder to achieve the same movement speed as adults'.

Kids have more muscle mass and less fat tissue than adults do, so they can store more oxygen during exercise. They can go longer periods of time without water intake than adults can, so they don't feel thirsty while exercising at **high rates** of heat production. However, like most other animals, kids do suffer from hyperthermia and dehydration just like adults do when they run for a long period of time in hot conditions.

In general, children can run faster than adults because they use less energy per unit of **body mass** to move around.

The highest speeds for 10-11 year olds, 12-13 year olds, and 14-15 year olds were 6.45, 6.77, and 7.70 m/sec. , respectively, while the average speed was 5.76, 6.01, and 6.47 m/sec. Untrained males in the schools have a smaller acceleration zone, and the length of the acceleration zone rises with age. Therefore, their maximum running speeds are lower than those of trained athletes.

Eleven-year-olds can run up to 9 minutes per mile, which is faster than most adults. They can cover a quarter mile in under **eight seconds** using **best practices**. This means that they can travel **nearly 100 yards** in every minute of play. In other words, an 11-year-old boy can run two miles in less than 20 minutes.

Ten-year-olds can run half a mile in less than 15 minutes, which is almost 2 minutes per mile. Nine-year-olds can run a third of a mile in about 12 minutes, which is more than 2.5 miles per hour. Eight-year-olds can run a tenth of a mile in less than 10 minutes, which is more than 3 miles per hour.

Seven-year-olds can run a hundredth of a mile in **less than 8 minutes**, which is more than 4 miles per hour. Six-year-olds can run a tenth of a mile in less than 6 minutes, which is more than 5 miles per hour.

A 14-year-old girl can run the 100m sprint in 13-14 seconds on average. To put it another way, you're slower than the typical 14-year-old female! A 14-year-old boy should aim for between 11 and 12 seconds. On average, a 12-year-old kid can run 100m in 15-17 seconds. That's faster than most adults!

The average time for **a 100m race** is 9-10 seconds. The fastest people ever recorded ran under **8 seconds**. Some athletes are capable of running flat out for hundreds of meters without stopping.

The maximum distance that someone aged 14 or over can run in 30 minutes is 100 meters. Any further than that and you risk injury to your joints from **excessive strain** on your muscles.

The average life span is 78 years. This means that if you started running at age 14 and kept going, you would reach age 100 in **two weeks**.

For a total of **eight minutes** and forty seconds In compared to **other boys** his age, a 12-year-old kid who can run a mile in eight minutes and 40 seconds is in the 50th percentile. Any time quicker than 8:40 is regarded a good time since it places the youngster in the top half of his age group. Anything over nine minutes is considered fast for a boy his age.

A 12-year-old boy can walk or run one kilometer (0.6 miles) in less than eight minutes. He is performing at **a moderate pace**. The first two minutes of running are very important because that's when you reach your peak speed. After that, you start losing energy at a constant rate regardless of how much or how little you eat or drink. A young athlete can improve his time by working out more often or trying different activities. For example, if a child can walk for an hour without stopping, he could try walking faster for a while to see how far he can go before needing to rest.

A 12-year-old boy can still grow taller and build muscle mass. He may be already at his maximum height, but he could have a longer leg span which is measured along with his height to determine what league he can play in. For example, a 13-year-old boy who is 1.80 meters (6 feet 0 inches) tall and who has a leg span of 2.20 meters (7 feet 4 inches) can play basketball.

In compared to other boys his age, a 12-year-old kid who can run a mile in eight minutes and 40 seconds is in the 50th percentile. Anything over 9:00 is considered fast for his age.

There are different ways of measuring speed. One method is to use a stopwatch and have the boy start at **one end** of the yard or track and back again. Or he can be given a distance and told to run it as quickly as possible. The important thing is that there be no cheating!

A young athlete's maximum running speed decreases as he gets older. He can run faster when young because his muscles are more flexible and his bones less dense. The number of muscle fibers in his legs increases during puberty, adding weight but not size to his legs. The more muscle mass he has, the slower he'll be able to run as he ages. A person's maximum running speed also depends on which leg is used for running. If the left leg is used instead of the right, it will be slower.

The average human being can run up to **about 17 miles** per hour (27 km/h). Young adults can run faster than this with training while children cannot. At **any age**, people who train hard can run faster than those who do not.
