Plan Description

Is This Plan For You?

This 4-week Half Marathon Base plan by GA Endurance is designed as the final preparation block before entering a longer structured training program.

It is ideal for runners who already have a basic training background and want to establish rhythm, reinforce aerobic consistency, and prepare their body for a more structured workload ahead.

This is not a standalone beginner plan, but a transition phase leading into a full progression system.

If you are starting from zero or are unsure about your current level, we recommend reaching out to us before beginning so we can guide you to the right starting point.


What You Can Expect

• A focused 4-week Base block preparing you for a longer training plan

• Controlled aerobic sessions to rebuild consistency and structure

• Light progression in volume without excessive fatigue

• Strong emphasis on pacing discipline and mechanical efficiency

• A smooth transition into more structured and demanding training phases


Coaching & Support

This plan includes Coach Access.

If you are unsure whether this plan is right for you—or if you need a different starting level—you can contact us anytime:

Requirements

To start this plan, you should:

• Have some prior running experience

• Be able to train consistently 3–4 times per week

• Be preparing to transition into a longer structured plan

A GPS watch or heart rate monitor is recommended for best results.


Final Note

This 4-week block is designed to prepare you—not to fully develop your performance.

It ensures that you enter your main training phase with better structure, improved aerobic readiness, and reduced risk of overload.
