The fitnessgram pacer test is a multistage acrobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each time you hear this sound. A lap should be completed each time you hear this signal. Remember to run in a straight line, and 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. Get ready, start!
