@myidolsare10 The pacer test and the beep test is, to my knowledge, a test of how fast one can run. So the Pacer test has a whole audio you have to listen to before the first beep and after that, you have to get to the other marked area and back before it beeps again. I'm pretty sure the beep test is the same thing except it doesn't have the audio explanation. Oh the test lasts until you can't make it back, it just keeps getting faster and faster.
Also, from what I've been told the Pacer test is illegal to do at schools in Canada (Don't know about anywhere else) because of casualties. I honestly think they just renamed it from "The Fitness Gram Pacer Test" to "The Beep Test" for legal reasons.
