The average 12 year can run as fast as his body lets him. As you mature you will gain muscle mass and the development between kids who just turned 12 and kids who have been 12 for 11 months is massive. I would imagine the average 12 year old could run a mile in about 8-14 minutes. As you get older this time will drop very quickly. I am 6'6, 195 lbs and I row crew, I can do it in about 5:30. But I dont like to because running is meant for low cardio for me.
a 12 year old boy can run average of 50kmh fast 12 year olds can go 70kmh when they ran the 100m they ran 12.8
I think that a 12 year old should run at least 45 minutes per day.
10 Minuit's for 1 mile. Don't push yourself to hard !
I'd have to say somewhere between 7-8 minuets. But it all depends if you just run the mile at school or compete on a track or cross country team.
I am a 12 yr old girl and I can run 1 mile in 5-6 minutes. An average 12 yr old runner can run 1 mile in 5-7 minutes, but an average 12 yr old runs it in about 8-12 minutes!
I am 12 year old boy, and my best full speed average is 17.2mph, but i am gifted with an athletic body.
im 11 and i go 12.5 mph but again this time was taken with no prep whatsoever or any fancy shoes so I say for a twelve year old about 13.7
