What is the key component of a Progression Run?

The key component of a Progression Run is the shift from a slow start to race pace before finishing the run at a slower pace. This type of training allows runners to gradually increase their speed over the course of the run, which helps to improve both endurance and speed. The idea is to start at a comfortable pace, progressively run faster, reach a sustained higher intensity, and then conclude the run by easing back to a slower tempo. This method effectively teaches the body to adapt to increased speeds and can simulate the experience of racing, where pacing strategies are crucial.

Other options suggest maintaining consistent paces or incorporating rapid intervals, which do not align with the primary aim of a Progression Run, as they focus on varying pace without the gradual build-up that characterizes this particular training technique.
