mine is: The FitnessGram PACER Test is a multi-stage aerobic capacity test that progressively gets more difficult as it continues. The 20-meter PACER Test will begin in thirty seconds. Line up at the start. The running speed starts slowly but gets faster each minute each time you hear this signal. A single 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, your test is over. The test will begin on the word start. On your mark, get ready, start.
