‘Fartlek’ is a Swedish word that means ‘speed play’. It’s a running style mixing speed and endurance. The main idea of fartlek training is to help the body get used to different speeds, making it faster for longer distances. Fartlek training stands out as a versatile workout method that injects variety and adaptability into your running routine. It involves altering your running pace within a single session, offering a delightful blend of challenges and benefits, including enhanced endurance, speed, and aerobic capacity. Unlike conventional interval training that adheres strictly to set periods of work and rest, fartlek training provides the freedom to adjust your pace and duration based on personal feelings, the terrain, and your fitness aspirations. It is a universally applicable exercise, suitable for roads, trails, tracks, or treadmills.
