This session is great to improve speed for runners. It is perfect for both runners and triathletes alike.
Each week I will be posting the Friday Fartlek Run Sessions that you can do to enhance your running. Fartlek is a Swedish term that runners often use and it means speed-play. See a previous post about training intensity (levels) to know how hard to work.
The inspiration for this session comes from an Instagram post from @coxelode57. Although the post isn’t in English the session is a good one.
