Overview

Base training builds the aerobic foundation that later, harder training sits on. Most of it is steady zone-2 endurance, supported by early-season strength and a gradual introduction of sweet spot as the weeks go on.

A 12-week winter block runs in three stages. Pure aerobic and strength first, then tempo and some sweet spot, then more sustained work. The aim is to reach spring with a higher chronic training load before building toward events like gran fondos, centuries or gravel races.

How many hours a week?

The sample week above is one way to lay out this goal. If you plan around a fixed number of hours, these example weeks show how 6, 8 or 10 hours can be split between a long ride, quality sessions and easy riding, using workouts from the public library.

Brought in from Base 2 to add work near threshold while most riding stays aerobic.

Tips to get it right

  • Keep easy rides truly easy. The common base mistake is riding zone 2 too hard.
  • In winter, a smart trainer makes consistent zone-2 volume realistic when it is cold and dark.
  • Consistency beats heroics. Regular moderate weeks build more base than the occasional huge one.

Frequently asked questions

How long should a base training phase be?

Eight to twelve weeks is typical, and dedicated riders often do longer over a full winter. The goal is to raise your chronic training load steadily before event-specific work.

How hard should base training be?

Mostly easy. The bulk is zone-2 endurance, with strength and a gradual introduction of sweet spot. Keeping easy days easy is what lets the volume add up.

Can I do base training indoors over winter?

Yes. A smart trainer makes consistent zone-2 volume practical in bad weather. TrainCraft can export workouts as .zwo, .fit, .erg and .mrc files for trainer apps and bike computers.
