On the basis of good basic training, the training form ideally follows with extensive interval units before moving on to the intensive variant. Intensive interval training is ultimately used by ambitious runners to work on their basic speed. The heart rate range is 90-95% of the maximum heart rate. The training takes place at or above the anaerobic threshold, i.e. in the "red zone". This requires the activation of fast-twitch muscle fibres and improves maximum oxygen uptake, lactate tolerance and pace hardness. The pace is fast (at competition speed or slightly below) and the breaks between efforts are longer than in the extensive form (suitable as training for shorter competitions such as 5km or 10km runs).

Interval training can be completed both on a track and off-road. The advantage of running on the track is that the runner always has control over the distance and the current running pace, which can promote the development of a sense of speed.

In interval training, it is important that the participants/groups try to cover approximately the same distance in the specified time for each interval or to complete a specified distance in approximately the same time. The various options for this type of training are as follows:

• Loop track: To ensure that the participants have enough space available for the run, they can be spread out on the loop track at the start. Using a stopwatch, each runner measures their own time for the specified distance. After the interval, the participants continue at a relaxed trot and start the next run after the break time has elapsed (variant: break on the spot). The participants moving at a relaxed trot must ensure that they do not hinder the runners who are in an exertion phase.
• Course: The defined course to be completed is marked. Participants start and stop their time independently (staggered start possible). The participants continue to move at a relaxed trot during the breaks, but make sure that they are back at one of the two possible starting positions at the end of the break time (variant: break in place). The sports leader defines the running routes for the outward and return routes to avoid collisions.
  Variant: it is also possible to complete a shorter route several times until the desired distance is reached. Here too, it is important to pay attention to the running directions so that there are no collisions. The breaks are carried out as described above, except that in this form the start/finish is always in the same place.
• Longer-distance loop run: A marker is placed on the route after every 3 kilometres (load) (e.g. balloon, route tape, wooden wedge). The participants keep moving after the interval (relaxed trotting), but make sure that they are back at the last marker at the end of the break time in order to start the next run. The participants who are in the recovery phase take care not to hinder the active runners. Ideally, the participants should be approximately back at the starting point after the last interval (2 intervals = 6 km running distance, 3 intervals = 9 km running distance), otherwise additional teaching time must be calculated for the return shift.
