Runners are pretty simple creatures. We typically only want one thing: to run faster. If you’ve spent any time with a runner you’ll typically find that they’re stubborn- I mean determined- people. That trait serves them well in the sport.
However, being one of the most determined people on the planet, I can safely say that all the will in the world won’t make me faster. If any runner wants to be faster, they have to train to be faster. One of the best ways to do that is by doing fartleks. Yes, fartleks. Funny name, but powerful speed training.
Fartlek is the Swedish word for “speed play.” Fartleks are a type of interval training for runners. It was developed in 1937 by Swedish coach, Gosta Holmer. Holmer developed this training for his cross country teams who had a terrible record. The effective speed plays focus on running faster than race pace to train. Fartleks were so successful that they have been widely adopted and used since.
