Holmer&#8217;s plan was to run faster than the race pace in training and focus on both speed and endurance training.<\/p>\n<p><strong>Fartlek training<\/strong><\/p>\n<p>Compared to <a href=\"https:\/\/www.time-to-run.com\/training\/intervals\" target=\"_blank\" rel=\"noopener\">interval training<\/a>, fartlek is less structured. Interval training is built on running a given distance at a certain time and at a certain rest between intervals. Fartlek is built around a given time. For example, 2 minutes are run at the desired pace (for instance 10km race pace), followed by a recovery jog until the next 2 minutes at the desired pace. You can do this anywhere. The terrain can consist of rolling hills or it can be flat, whatever you prefer or you have available.<\/p>\n<p>The effort, duration and terrain are all determined by the runner. As mentioned earlier, fartlek is suitable for all types of terrain, even the running track.<\/p>\n<p>Fartlek develops both aerobic and anaerobic fitness. It has become a popular form of training among runners, offering a nice variation to their training routine.<\/p>\n<p>Fartlek is basically a workout where a changing pace brings more variety and enjoyment to your training. It is similar to interval training. Interval training is more disciplined and precise in terms of goals, time and distance. <a href=\"https:\/\/www.time-to-run.com\/training\/fartlek\" target=\"_blank\" rel=\"noopener\">Fartlek<\/a> is not as challenging and can be adapted to suit everyone&#8217;s needs and different kinds of terrain.<\/p>\n<p><em>Written by <a href=\"https:\/\/doyle-pr.com\/\" target=\"_blank\" rel=\"noopener\">Piia Doyle<\/a><\/em><br \/>\n<em>translated by U.N.A Doyle<br \/>\npage updated 2025: further fartlek information links added<\/em><\/p>\n<p>Further articles under the Fartlek method:<\/p>\n<ul>\n<li><a title=\"The definition of Fartlek\" href=\"https:\/\/www.time-to-run.com\/training\/methods\/fartlek\/definition-of-fartlek.htm\">The definition of Fartlek<\/a><\/li>\n<li><a title=\"The creation of a Fartlek session discussed\" href=\"http:\/\/www.time-to-run.com\/training\/methods\/fartlek\/creation-fartlek-session.htm\">The Creation of a Fartlek session discussed<\/a><\/li>\n<li><a title=\"The Top 6 Favourite Fartlek Sessions\" href=\"http:\/\/www.time-to-run.com\/training\/methods\/fartlek\/top6.htm\" target=\"_blank\" rel=\"noopener\">The Top 6 Favourite Fartlek Sessions<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>So what is Fartlek? &#8211; The word fartlek is a Swedish word that translates directly into \u201cspeed play\u201d.
