Base training is the foundation of cycling conditioning, and it works best when done patiently. The goal is to accumulate a large volume of low-intensity riding over weeks and months, which develops the aerobic system without placing excessive strain on the body. Riders who rush this phase and push into harder intensities too early often find that their fitness peaks quickly and then stalls or regresses.
Most of your base training should sit in Zone 2, a conversational effort where you can breathe comfortably but would not want to sustain a lengthy discussion. At this intensity, your body preferentially burns fat for fuel, builds mitochondrial density in your muscles, and improves cardiac output over time. These are slow changes that take weeks to accumulate, which is why base phases are typically four to eight weeks long before intensity is added.
Periodisation is the process of organising your training into structured blocks, alternating between phases of building, higher intensity, and recovery. For most cyclists, a base phase comes first, followed by a build phase that introduces harder work, and then a competition or peak phase. This structure prevents the body from adapting to a single stimulus and keeps fitness progressing in a controlled direction.
