That depends on the fitness of the girl. It is also questionable, if a 12 year old girl should run very long distances like the marathon distance at all. She should wait for that some years. She should run 5k or 10k distances first, if she did that, she can do exercise for half marathon. The training should be varied (for example faster - slower) to keep motivation and fun, especially when people are that young. About 30 to 60 minutes a day should normally work (maybe more after a couple of weeks), so the distance depends on how fast you are.
Around 1:30, and that is out of shape for me!
14. 56 is a good time
Around 13 seconds
An average time for a 14-year-old running the 50 meter dash is around 9 seconds. For a 100 meter dash, it would be about 13 seconds.
depending on how fast you can run i'd say 3:00-3:30
i ran a 24.7 200 in state and got 4th so.. and if you run under a 12 in the 100 meter dash that's pretty good, i run a 12 flat.
its alright
a 11.9 and lower is a good time
27-24
no...
You're good if you are 14, 5'7" and 138 lbs., and can run the 40 yard dash in 4'72 and the 100 meter in 12 seconds.
If there were sports for animals a Cheetah would be good at the 100 meter dash.
30 seconds
