Answer
Hello,

Find a hill in your area, and run sprints up the hill. That will build strength and speed. If possible, you should invest in a training parachute. This is one of the top ways for athletes to increase their speed. I also recommend getting involved in track, this will teach you the correct form for running.

I have a answer on here where I tell someone the concept of running properly.

There is a correct form for running. A long stride doesn't always equal speed. It is the push from steps that are placed slightly in front of you and driven back behind you strongly.
