The fitness gram pacer test is a multistage aerobic capacity test, that progressively gets more difficult as it continues. The twenty meter pacer test will begin in 30 seconds, line up at the start. The running speed starts slowly, but gets faster each minutes after you hear this signal (beep). A single lap should be completed every time you here this sounds (beep). Remember to run in a straight line, and run as long as possible. The second time you fail to come,etc a lap before the sound, your test is over. The test will begin on the word start. On your mark, great ready, start. <3
