A relatively unstructured type of continuous training that originated in Scandinavia. It is performed over natural terrain. A typical session lasts about 45 min. The route is predetermined, but the pace is varied from fast bursts to jogging (or walking), according to the terrain, and the disposition of the runner. Depending on the precise composition, fartlek training can improve both the aerobic and anaerobic capacity of the athlete. Fun is the main objective, with distance and time of secondary importance. Many coaches use fartlek training because it provides relief from highly structured types of training.
