<P> Fartlek , which means `` speed play '' in Swedish , is a training method that blends continuous training with interval training . Fartlek runs are a very simple form of a long distance run . Fartlek training `` is simply defined as periods of fast running intermixed with periods of slower running . '' For some people , this could be a mix of jogging and sprinting , but for beginners it could be walking with jogging sections added in when possible . A simple example of what a runner would do during a fartlek run is `` sprint all out from one light pole to the next , jog to the corner , give a medium effort for a couple of blocks , jog between four light poles and sprint to a stop sign , and so on , for a set total time or distance . '' The variable intensity and continuous nature of the exercise places stress on both the aerobic and anaerobic systems . It differs from traditional interval training in that it is unstructured ; intensity and / or speed varies , as the athlete wishes . Fartlek training is generally associated with running , but can include almost any kind of exercise . </P>
