Base building

Mesocycle training is one of those terms that sounds more complicated than it really is. In plain English, it simply means a focused block of training inside a bigger plan. Usually, that block lasts around 4 to 6 weeks and is built around one main goal, such as improving aerobic endurance, lifting FTP, sharpening VO2max, building race-specific power, or adding strength without wrecking everything else.

Base building sets the ceiling for your entire season, yet many cyclists repeat the same early-season training mistakes year after year. This guide highlights the base-building mistakes holding you back, explains what to avoid during base training, and shows how aerobic base cycling, progressive overload, and consistent base riding create a training plan that actually delivers results.
