Speedwork: An Overview
Training to Run 10Km (6.21 Miles)

Training is a process of simulating racing conditions to enable the runner to adapt. Ideally, the different facets of your training plan should complement each other so that on race day, you have no relative weaknesses and your mind and body are ready to perform. By planning a well-balanced training program and doing it, you can prepare yourself for two of the most essential race-day challenges: (1) completing the distance, and (2) maintaining a certain pace.
  1. First, read "Speedwork: An Overview; Training for a 5k".
  2. Next, read the brief article below.

The basic differences between training for 5k and 10k are as follows:

  1. Higher mileage at slower average pace for 10k than for 5k.
  2. Higher volume of running at race pace in workouts for 10k than for 5k.
  3. Less frequent racing at 10k yields better results. 5k racers can race more often and sooner after a previous race.
  4. 5k runners require more races to run their best times of the season than 10k runners.
  5. Faster stride rate and longer stride length is needed to run faster at 5k than 10k.
  6. 5k's are run at higher aerobic levels of performance than 10k's, and may require a small measure of anaerobic training for fast starts and kicking. Keep in mind that anaerobic energy stores last for seconds, not minutes, so 5k's should still be trained for aerobically.
  7. 5k's require more focus on improved running technique than 10k's because mechanical efficiency becomes more important at faster speeds.
  8. 10k's require more focus on improved heart and respiratory functioning: thus the emphasis on more mileage and longer race pace repeats when doing intervals or faster runs. Developing the endurance of the respiratory muscles with race pace running in practice is more important in the 10k due to the longer period of time one is breathing deeply while running.
  9. The weeks or months of training for 10k should always precede training for 5k so that the endurance that is developed by 10k training will provide a foundation for the faster 5k training. Recovery from 5k race pace workouts and races will be faster this way and ultimately, one's 5k times will be faster as well.
