So, it’s back and forth to the time of single beeps until three beeps announces the next level of faster pace. They run back and forth at the same pace waiting at the end for the next beep until another series of three beeps indicate the “next level” and the pace picks up. Give the instructions, start the tape, wait for the first set of three beeps and runners begin at a pace “just fast enough” to arrive at the cone where they wait until the next beep sounds and they start back. Most fit individuals reach their maximum around 10 minutes, only professional level athletes make it above level 12 or so (there are 21). Ostensibly to the highest level it takes just over 20 minutes but no one has been verified as completing it even though several have claimed to do so. You start the tape and don’t stop it until the last person taking the test has dropped out. The tape uses “beeps” to time the exercise. The “game” or “exercise” is easy to set up and just as easy to perform (except for the running part) but it does need some explanation to those you want to administer it to.
