Answer 1

Put 5 lb ankle weights on and practice running with them so that when you run without them you will run faster

Answer 2

it depends if you're a guy or a girl. for a girl thats really good and for a guy thats decent.  to improve just practice. run 400s....they help with endurance as well as speed

Answer 3

yes, that's pretty good for a 13 year old.

do lots of upper leg workouts.

and stretch reallly good before you run.
