+            The FitnessGram Pacer test is a multistage aerobic 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 minute after you hear this signal *boop*.
+            A single lap should be completed each time you hear this sound *ding*. 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. 
+            On your mark, get ready, start.
