Fartlek, a Swedish term for “speed play” is a form of interval training involving continuous activity with randomised short bursts of high intensity efforts. This creative, less structured form of training is a great way to mix up your run workouts and challenge your body to become faster over longer distances. Unlike intervals, where you stop or walk for recovery, Fartlek is continuous running with varying paces, blending endurance with speed. The randomised nature of Fartlek training is designed to continuously shock and stress the body systems, providing both physical and mental gains.


How Does Fartlek Training Work?

Fartlek training can be structured in a number of different ways and can be tailored toward individual training goals. Different combinations that can be programmed include:

  • Fixed distance for the repetition
  • Fixed time for the repetition
  • Varying distance/time for the repetition
  • Varying pace for both the repetition and recovery period

Fartlek sessions are usually 20 minutes or more in duration (including a warm up and cool down) and can be done almost anywhere.
