Complete Beginner Masters Half Marathon Training Plan for Road or Trail
This structured 20-week beginner half marathon plan combines running drills, steady aerobic training, strength training, and nutrition to improve your running fitness, form, strength, and endurance so you can complete a trail or road half marathon without high-intensity training.
Designed for beginners starting at 3 km and suitable for masters athletes who prefer lower intensity training. This progressive plan relies primarily on Zone 2 work, including hills, to gradually build weekly distance. Long runs peak at 19 km two weeks before race day. The outcome is improved aerobic capacity, stronger muscles, and increased fitness with low risk of burnout or injury.
What You’ll Do Each Week:
✅ 2 steady runs based on time
✅ 1 keystone distance-based run on the weekend
✅ 1 weekly skills session for form development (20-min, very light)
✅ 2 strength workouts guided by a progressive plan with print and video support
✅ 1 full rest day, with the option for another if needed
Coaching Support Built In:
• Weekly training notes to guide your focus
• Detailed workout descriptions inside each session with heart rate targets
• Direct email support from Coach Tammy Lee
Included Guides and Tools:
🔥 High Protein Healthy Recipe eBook
🔥 Progressive Strength Training Plan with templates

This plan is repeatable. Each round builds improved pacing, stronger lifts, and consistent nutrition habits that compound over time. After your race, update your lactate threshold zones and begin again. You will run faster and more efficiently than your first cycle.
This is a holistic plan. I have coached hundreds of beginner runners and I am a masters runner. I have consistently seen that unless you are experienced and pursuing higher competitive goals, high-intensity training is not required to complete a race.
There's a lot of joy in this journey!
