lots of places to run
All of the threads people have posted for you to try and run are not bad ideas. An other one is finding out if your parents mean 2 blocks in all directions (not counting the block your house is on) or 1 block (counting the block your house is on) this would give you a wider range to work with.
I do like the idea of maybe trying to get your parents involved either they could go with you or maybe drive you to a local track to run. If you do this remeber to change directions halfway through your work out to avoid hip problems.
No matter what you deside you can do you should try to work out around 5 days a week. If this is to much then start with 3 and work up and you can always do more than 5 depending on quality of your work outs and body recovery. Listen to your body and and try to push with out over doing it. You should mix your work outs up between speed and distance. At least once a week you should run as far as you can. An other day, preferably a day or two later you should try for speed, run a ways then sprint a ways, or sprint the two blocks then jog back and do it again. You should do this as many times as you can and as it gets easier you should increase the number of reps. on all of the other days you are going to want to run a medium distance at a medium pace. What you should use to set your pace is your pulse. Do this by counting it for 30 seconds and times by 2. You will want your pulse up to 140 or higher for at least 20 minutes.
Rember to warm up and cool down properly.
