Awesome job!!!! If you want to keep running, and I assume you're in a school that doesn't have a track team yet, ask your mom to make an appointment with the track coach at the local high school and get his/her input and also pay a visit to your doctor. Between them, they can probably come up with a great plan to help you keep running without getting burnt out or overuse injuries. Good luck to you and I hope you are able to keep running!!!

Congratulations on your race Alex.  I encourage you to stay physically active and running is one way to do that.  At your age though, there are physiological issues with doing a lot of running, because your body is still growing.  You and your mom should discuss these issues with your doctor to come up with a good plan for your running that will also avoid injury.
