How It Works
See What a Week Looks Like
Here’s a sample week from the advanced half marathon training plan so you can see how the training is structured and how each day supports race-specific performance.
Week 7 – Build Phase
This week continues progressing race-specific endurance, aerobic strength, and fatigue resistance as training begins shifting more directly toward half marathon performance. The focus remains on controlled execution, sustainable pacing, and maintaining recovery between key workouts.
At this stage of training, the goal is not to force fitness through excessive intensity, but to continue stacking high-quality, repeatable weeks together. Prioritize efficient pacing and smooth mechanics throughout your harder efforts.
Focus this week on:
– Staying controlled during sustained efforts
– Maintaining relaxed mechanics late in workouts
– Running recovery days truly easy
– Supporting recovery between quality sessions
– Building confidence with race-specific pacing
Remember: strong half marathon performances are built through aerobic efficiency and disciplined pacing—not constantly running hard.
