Fartlek
Fartlek — Swedish for 'speed play' — mixes faster and easier efforts freely and by feel within one continuous session, blending steady and interval work.
Overview
Fartlek is a Swedish word meaning 'speed play', and that playful spirit is the whole idea. Within one continuous session you vary your pace freely — picking up the effort to a lamppost or the top of a hill, then easing back — without the rigid structure of timed intervals.
Because the surges are chosen by feel rather than a stopwatch, fartlek blends the continuous nature of steady-state work with the variety of intervals. It suits open, unstructured settings like a run through a park, and it keeps sessions engaging by letting the terrain and your mood shape the efforts.
It scales naturally to any level: a beginner might sprinkle in just a few gentle pick-ups, while more experienced athletes make the surges longer or firmer. There are no wrong choices, which is part of what makes it approachable.
How to do it
- 1Begin with easy, relaxed movement.
- 2When you feel like it, pick up the pace toward a landmark ahead.
- 3Ease back to a comfortable pace to recover.
- 4Repeat these free pick-ups and easy spells throughout the outing.
- 5Wind down with easy movement at the end.
