Plan Description

Is This Plan For You?

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

It is ideal for runners with a consistent running background who want to reinforce aerobic rhythm, pacing control, and training structure before moving into a more demanding half-marathon progression.

This plan is suitable for athletes who are beyond the beginner stage but still want a controlled, efficient transition into structured training without jumping too quickly into high volume or intensity.

Use the code GAFREE at checkout to access this plan for FREE.


What You Can Expect

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

• Controlled aerobic sessions to reinforce consistency and structure

• Moderate progression in training load without excessive fatigue

• Strong emphasis on pacing discipline and movement efficiency

• A smooth transition into more structured half marathon training

• Clear workouts using pace, heart rate, or perceived effort
