   • 1992, Hal Higdon, “Fartlek: A Time-tested Treasure”, in Kathleen A. Becker, editor, Run Fast: How to Train for a 5-K or 10-K Race, Emmaus, Pa.: Rodale Press, →ISBN, pages 128–129:

     In an article in Athletics Journal, Paul A. Smith described fartlek as "a continuous overdistance run with numerous faster-paced interval runs interspersed, until the runner feels tired, but not exhausted." Smith claimed that because fartlek existed in the mind of the runner as a form of play, it deemphasized the feeling or perception of fatigue. […] In a typical fartlek workout, you pick some landmark such as a tree or a bush and sprint to it, then jog until you've recovered.
