Question: how fast does an average 13 year old run?
Answer: For a 12–13yr old, the top speed usually is between 12 and 16.4mph. But don't take my word for it because it is not always the case. Yup, you can also get some of them reaching speeds of up to 17 mph with a very small number of them just shy of 18 mph. However, this is very rare to observe in such a big world.
