Fartlek runs, the Swedish word meaning “speed play,” are a great way to ease back into running fast after time off. They can be mixed into long runs or done during a short workout. After a warm up, a good place to start is by running hard for one minute, then slowing to a jog for the next minute. Alternate running one minute “on,” and one minute “off.” No set pace has to be chosen for the hard portions, but aim to have a consistent effort on each hard portion of the workout. If one minute feels too long, shorten the hard portion of the workout and extend the rest portion. This workout is a good option that can be customized for sprinters, mid-distance runners, and distance runners alike. Just adjust the number of repeats to fit with your current fitness level.
