"Fartlek" is a Swedish work meaning speed-play. Fartlek runs outdoors are often done between natural landmarks - such as let's pick up the pace between those two signs or fenceposts. On a treadmill, it is not quite so random, but the basic principle still applies - inject short periods of fast running into an otherwise steady base run.
