• Answer:

  I run in high school and the best way to get better is just to practice. If you run long distances you will be able to run longer and quicker. When you run long distances, no matter how hard it gets, don't stop running. If you are running slower than you walk thats better than running. Also, do about 4 200s during practice and take a rest in between that is the amount of time it took you to run the 200s.
