Beep test scores vary by age, sex and fitness level. You might have heard reaching level 21 is a“perfect score”, but this is a myth. Ultimately, a“good” score depends on who is being tested.

Or as manager Adrian Heath called it, in a bit of a Freudian slip, the “bleep test.” It’s a survival of the fittest, with an official name: the 30-15 Intermittent Fitness Test.

Perhaps the most famous challenge is the bleep test, where the players will run between two sets of cones 20 metres apart at the sound of a bleep and must cover the distance before it sounds again.
