Repetition training consists of running fast over distances longer than in interval training, and with complete rest, instead of jogging, between the fast running. Due to the increase in distance run and the speed, the athlete will go into oxygen debt. Therefore, he or she will need more time to recover from this sort of running. Here, the athlete will be running at a high pulse rate, about 80-90% of their maximum, and will not run many of these repetitions. This type of running increases the runner's ability to go into oxygen debt, i.e. anaerobic effect.

Examples of repetition training sessions are as follows:

For the shorter distance runner
6 to 8 X 200 metres; 5 to 7 X 300 metres;
4 to 6 X 400 metres; 2 to 3 X 800 metres.

For the middle distance runner
4 to 6 X 600 metres; 4 to 5 X 800 metres;
3 to 4 X 1000 metres; 3 to 4 X 2000 metres.

For the longer distance runner
6 to 8 X 1000 metres; 4 to 6 X 1500 metres;
3 to 5 X 2000 metres; 2 to 3 X 3000 metres.

Quality is paramount in this type of workout. Therefore, the speed of the repetition should be close to, if not faster, than actual racing pace. For example, the 4 minute 1500m runner would run the 800 meters reps in about 2 minute and 8 seconds or better. Similarly, the 13.45 5k runner would run the 3000m reps in about 8minutes and 15 seconds or better. It is common amongst many international athletes that I know, including myself, to do 2 fast repetitions at a distance about 2/3 of racing distance.
