For the people wondering it says: The Fitness Gram Pacer Test is a multi-stage aerobic capacity test that gradually increases in difficulty as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The driving speed is slow at first, but increases minute by minute after hearing this signal. *beep sound* One round is completed each time you hear this sound.Remember to run in a straight line and run as long as possible. If you fail to complete a second lap before the tone sounds, the test will end. The test begins with the word "start." Once you've achieved your goal, get ready and get started.
