ok...
The test is a recorded cd/tape with programmed ''beeps''.
You will start on the beep, then you must run to the other line which is 20 meters away and step on the line on the secound beep, and so on.
The test will go faster and faster.
The FIBA test have 3 ''steps'' tha you must clear, every step will go faster than the other.
So... After 86 laps you are finnished( i did 87:
)
