A training method that incorporates varying both speed and terrain is known as?

Fartlek training is a method that uniquely combines both speed and terrain variations during a workout. The term ‘Fartlek’ is Swedish for ‘speed play’ and reflects this dynamic approach, where athletes alternate between different paces (such as sprinting and jogging) and terrains (like running on grass, hills, or roads) within the same training session. This method not only enhances cardiovascular fitness but also improves a runner’s ability to adapt to varying conditions encountered in competitions. It emphasizes spontaneity and variety, which can lead to greater improvements in overall performance, making it an effective training strategy for endurance athletes. This versatility sets Fartlek training apart from other methods that may focus on more uniform or static routines.
