The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more hard as it continues. The 20m test will begin in 30sec. Line up at the start. The running speed starts slowly but gets faster each minute after you hear a signal. One lap should be completed each time you hear this sound. Remember to run in a straight line and run as long as possible. The second time you fail to complete a lap before the sound your test is over. The test will begin on the word start.
