What are the best training methods for training for 1500 Meter run?

because the 1500 is a shorter distance run you want to practice your stride, you want to have a long stride, but not to long. I would also do the beep test at least once to see what your vo2 max level is. The higher your vo2 max level is the more efficiently oxygen is transported around your body. mostly just run 1500 meters and run faster and faster each time and you will improve very quickly.
