Each week I will be posting the Friday Fartlek Run Sessions, most that you can do in under 60 minutes to enhance your running. Fartlek is a Swedish term that is often used by runners and it means speed-play. See the previous post about training intensity to know how hard to work. If you are working directly with Coach Ray he will in most cases prescribe either a Pace Zone or Heart Rate Zone to work within if you are training with these tools.
This Friday Fartlek Run features 8×4-minute tempo intervals at Level III — a controlled, sub-threshold effort that builds aerobic strength and pacing discipline. Ideal for runners and triathletes preparing for half marathons, marathons, and longer events, this session delivers quality endurance work without excessive fatigue, making it perfect for both early build phases and taper periods.
