Which running method involves easy running followed by more strenuous efforts to increase distance?

The running method that involves starting with easy running and gradually incorporating more strenuous efforts to build distance is referred to as a progression run. This type of training is designed to help runners increase their speed and endurance by systematically increasing the intensity of their run.

During the initial phase of a progression run, the pace is relaxed and allows the body to warm up appropriately. As the run continues, the intensity is ramped up, which pushes the runner to challenge themselves and improve their overall performance. This technique is beneficial for developing pacing strategies, increasing stamina, and preparing for longer races.

In contrast, other methods such as the long run focus primarily on building endurance at a steady, often slower pace, while recovery runs prioritize rest and light activity to aid in post-exercise recovery. A base run typically emphasizes maintaining a consistent effort over time, rather than changing the intensity throughout the run. Progression runs specifically combine these elements of easy and hard efforts over a single session, making them unique in their training approach.
