Final answer:
When running the pacer test, it's important to pace yourself, cross the line before the beep, and not leave too soon.
Step-by-step explanation:
The statement "When running the pacer test, you want to pace yourself, cross the line before the 'beep,' and do not leave too soon" is True.
When running the pacer test, it is important to pace yourself so that you can maintain a consistent speed throughout the test. Crossing the line before the "beep" means that you have completed the required distance within the given time. Leaving too soon means that you did not run the full distance.
