"Intervals and other types of speed work are essential to improve running speed"
About this Quote
The intent is practical and almost parental: if you want speed, you have to practice speed. Intervals, tempo runs, and other structured efforts aren’t optional accessories for “serious” runners; they’re the mechanism that teaches the body to move efficiently under stress. The subtext is that endurance alone can make you durable, but it won’t necessarily make you faster. Speed is a skill, not a personality trait, and skills require rehearsal.
Context matters because Shorter helped define modern American distance running in the 1970s, when training was becoming more systematized and scientific, shifting away from pure grit narratives. His statement reflects that era’s emerging consensus: aerobic base is foundational, but performance gains come from targeted stress and recovery. It also carries an athlete’s realism about trade-offs. Speed work is “essential” because it’s uncomfortable, disruptive, and easy to avoid. The phrase draws a line between running as recreation and running as craft, where improvement is engineered rather than wished into existence.
