Fast+entense training or Slow-long time?

Question

when i run.

should i do spints until im tired then train/push myself.

Or run until im tired.

which is more effective?

Answer 1

It depends what type of races that you compete better in. If you are a sprinter then do short but all out training. But if you do better with distance then train long but hard! Either way you are going to be tired and get a good workout!

Answer 2

It depends on what your goals are, but you need to both.

The two types of running train different systems in your body. The percentage of each that you do depends on what your goals are. If you are training for long distance running, then the majority of your training should be long and easy, with periodic trips to the track for sprints. If you are training for short events, you need to swap the emphasis.
