Why it is important to pace during aerobic activity?

Answer 1

If you don't pace yourself, you will get tired near the end of your race. Those who do pace themselves will have more energy at the end and will pass you up. Only pace yourself in 200s and longer. If you are capable of sprinting a 200 then you do not need to pace.

Answer 2

to stop yourself from tiring out so you can run for a longer period of time. Also to reduce the risk of injury.

Answer 3

You need speed to know how fast you're going.
