Plan Description

Is This Plan For You?

This 28-week Half Marathon Beginner plan by GA Endurance is designed for runners who want a long-term, structured progression with a strong focus on sustainable performance development.

It is ideal for athletes who can already run 5–8 km continuously and prefer a gradual, well-controlled approach to improving endurance, pacing, and durability over time.

If you want to build your performance step by step—without rushing and with maximum stability—this plan provides a comprehensive pathway.


What You Can Expect

• A structured 28-week progression with extended Base development

• Gradual and controlled increase in volume with clear intensity management

• Strong emphasis on aerobic capacity, steady-state strength, and long-run durability

• Consistent long runs and steady sessions to improve pacing stability

• Integrated testing phases to track progress and recalibrate training zones

• Simple, easy-to-follow workouts using pace, heart rate, or perceived effort

• Optional strength guidance to support injury prevention and long-term consistency
