SpeedplayFartlek

SpeedplayFartlek is a training framework that blends the flexible pacing of fartlek workouts with deliberate, frequent changes in pace intended to simulate race-day fluctuations. The term is not widely standardized and is used largely in coaching circles as a concept rather than a fixed protocol.

In practice, sessions begin with a warm-up, followed by a main set where the runner or cyclist alternates between periods of faster effort and easier recovery without strict prescriptions. The length of hard segments can range from 30 seconds to several minutes, while recovery intervals are often equal to or shorter than the work segments. The pacing is typically guided by perceived exertion or heart rate, rather than prespecified splits, allowing for spontaneous tempo shifts.

SpeedplayFartlek emphasizes perceived effort, running economy, and lactate tolerance. It can be tailored to different goals, such as aerobic base development, threshold training, or race-specific preparation, and can be adapted for running, cycling, or mixed disciplines.

Practical considerations include ensuring adequate recovery between hard bursts, avoiding excessive total distance on hard days, and gradually increasing difficulty to reduce injury risk. Because the structure is variable, it can be less predictable for load management but can enhance enjoyment and engagement.

Related methods include classic fartlek, structured interval training, and tempo runs. The approach is often included as part of broader periodization plans, with guidance from coaches to balance intensity with volume.
