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.
