How Fartlek Training Works
Fartlek (Swedish for 'speed play') mixes fast and easy running in an unstructured or semi-structured format.
Formula
Average Pace = (Fast Fraction x Fast Pace) + (Easy Fraction x Easy Pace)
Benefits
Fartlek builds both speed and endurance in a single session. The unstructured nature makes it mentally refreshing compared to rigid interval workouts.
Esempio Risolto
5-mile fartlek with 30% at 7:30/mile and 70% at 10:00/mile.
- 01Fast fraction = 30 / 100 = 0.30
- 02Average pace = 0.30 * 7.5 + 0.70 * 10 = 2.25 + 7.0 = 9.25 min/mile
- 03Total time = 9.25 * 5 = 46.3 min
- 04Fast distance = 5 * 0.30 = 1.50 miles
- 05Easy distance = 5 * 0.70 = 3.50 miles
Domande Frequenti
What is fartlek training?
Fartlek is a training method that alternates between faster and slower running during a continuous run. Unlike intervals, the fast segments can vary in length and intensity.
How often should I do fartlek workouts?
One to two fartlek sessions per week is typical, with easy runs and a long run on other days.
Is fartlek good for beginners?
Yes. Beginners can start with short bursts of faster running (30-60 seconds) followed by longer easy segments. It introduces speed work in a low-pressure way.
