What’s Inside the 10-Week Plan
An intermediate plan should be more than just mileage. This one includes a variety of run types to help you build endurance, increase speed, and stay injury-free:
🏃♂️ Easy Runs
These form the aerobic foundation of your training. Run at a conversational pace to build endurance without burning out.
⏱️ Tempo Runs & Intervals
Boost speed and mental toughness with structured workouts designed to make race pace feel easier.
🗓️ Long Runs
The backbone of your half marathon prep. You’ll build gradually to peak distance, with recovery built in.
💪 Cross-Training & Strength
Incorporate non-running days with cycling, swimming, or strength work to build a well-rounded, resilient body.
😴 Rest & Recovery
Strategically placed rest days help prevent overtraining and support adaptation.
Why 10 Weeks?
A 10-week half marathon training plan is the sweet spot for intermediate runners—it’s long enough to build fitness, but short enough to stay focused and motivated. It’s also ideal if you’ve recently run a race and want to maintain momentum.
