Marathon Beginner Training Plan
Build endurance safely with a progressive 16-week beginner marathon plan
This 16-week beginner program emphasizes gradual mileage increases, injury prevention, and aerobic base building. Ideal for runners who have completed a 5K and can run 30 minutes continuously.
How to Use This Training Plan
Getting Started
This 16-week program is designed to take you from a 5K runner to successfully completing your first marathon (42.195 km / 26.2 miles). The plan emphasizes gradual progression, injury prevention, and building a strong aerobic foundation. Success requires commitment, patience, and trust in the process.
Before You Begin:
- Ensure you can comfortably run 5K continuously and have a weekly base of 15-20 kilometers
- Get medical clearance, especially if you're over 40 or have pre-existing health conditions
- Invest in quality running shoes and replace them every 500-800 kilometers
- Clear your schedule—this is a significant 16-week commitment requiring 4 training days per week
- Choose a goal marathon race and register to stay motivated
Understanding the Structure
This plan follows a 4-day-per-week structure with a focus on progressive long runs, aerobic development, and strategic recovery. The program is built around three key workout types:
Easy Runs:
- The foundation of your training (80% of your weekly mileage)
- Run at a conversational pace where you can speak in full sentences
- Heart rate should stay around 60-70% of maximum
- These build your aerobic base and allow recovery between hard efforts
Tempo Runs (Marathon Pace):
- Sustained efforts at your goal marathon pace
- These teach your body to run efficiently at race pace
- Start with 3 km tempo segments and build to 8 km by Week 12
- Include proper warm-up and cool-down
Interval Sessions:
- Faster efforts (10K or half-marathon pace) with recovery periods
- Build speed, running economy, and VO2 max
- Examples: 5 × 800m or 5 × 1km with easy-paced recovery jogs
- Always include adequate warm-up and cool-down
Long Runs:
- The cornerstone of marathon training
- Build from 8 km in Week 1 to a peak of 28 km in Week 12
- Run these at an easy, comfortable pace (slower than marathon pace)
- Practice nutrition and hydration strategies during these runs
Your Weekly Schedule
The plan typically follows this pattern (adjust days to fit your schedule):
- Monday: Rest or cross-training (swimming, cycling, elliptical)
- Tuesday: Easy or tempo run
- Wednesday: Rest day (critical for recovery)
- Thursday: Quality workout (tempo or intervals)
- Friday: Rest day
- Saturday: Easy run
- Sunday: Long run (the most important session of the week)
Important: Never schedule long runs on consecutive days with quality workouts. Always have at least one rest day before your long run.
Pace and Intensity Guidelines
Understanding and respecting different training paces is crucial for marathon success:
Easy Pace (Most of your training):
- You should be able to hold a full conversation
- Breathing is comfortable and controlled
- Rule of thumb: 60-90 seconds per kilometer slower than marathon pace
- If in doubt, go slower—you cannot run easy runs too slowly
Marathon Pace (Tempo workouts):
- Your goal race pace
- Breathing is rhythmic but elevated
- You can speak in short sentences but prefer not to
- This should feel "comfortably hard"—sustainable for hours
10K/Half-Marathon Pace (Intervals):
- Significantly faster than marathon pace
- Breathing is heavy and labored
- You can only speak a few words at a time
- This should feel challenging but controlled
What to Expect Each Week
Weeks 1-4: Foundation Building
- Focus on consistency and establishing your routine
- Long runs progress from 8 km to 14 km
- Introduction to tempo running at marathon pace
- Your body is adapting to regular training stress
Weeks 5-6: Recovery and Consolidation
- Week 6 is a cutback week to allow adaptation
- First interval session introduced in Week 5
- Time to assess and adjust your training if needed
- Don't skip the recovery week—it's when your body gets stronger
Weeks 7-9: Volume Building Phase
- Long runs extend from 18 km to 22 km
- Weekly mileage increases significantly
- More challenging tempo and interval sessions
- This is physically and mentally demanding—stay committed
Week 10: Mid-Program Recovery
- Reduced volume to prevent overtraining and injury
- Use this week to address any niggles or fatigue
- Mental and physical refresh before the final push
Weeks 11-13: Peak Training
- Your highest mileage weeks
- Long runs reach 24-28 km (Week 12 is your longest)
- Most challenging tempo and interval sessions
- You'll feel tired—this is normal and expected
Weeks 14-16: Taper Period
- Dramatic reduction in training volume
- Maintaining intensity but cutting mileage
- Your body is recovering and absorbing all the training
- You may feel restless or anxious—trust the taper
Common Challenges and Solutions
"I can't complete a workout as prescribed"
- Slow down—most beginners run their easy days too fast
- Break the workout into smaller segments if needed
- It's better to complete a modified workout than to stop halfway
- Adjust the next session if you're still struggling
"I'm always tired and my legs feel heavy"
- You may be running too fast on easy days
- Ensure you're getting adequate sleep (8+ hours during peak weeks)
- Check your nutrition—are you eating enough carbohydrates?
- Consider taking an extra rest day or reducing a workout
"My long run pace is much slower than my goal marathon pace"
- This is completely normal and expected
- Long runs should be run 60-90 seconds per km slower than marathon pace
- The purpose is building endurance, not practicing race pace
- You'll be amazed at how much faster you can run on race day when fresh and tapered
"I missed a week due to illness or injury"
- Don't try to make up missed training—jump back into the current week
- If you miss more than a week, consider repeating 1-2 weeks
- For injuries lasting 7+ days, consult a physiotherapist
- Health always comes before training—one missed week won't ruin your marathon
"The taper is making me anxious and restless"
- This is extremely common—trust the process
- Your body is recovering and storing energy
- Focus on sleep, nutrition, and mental preparation
- Resist the urge to add extra workouts—you won't gain fitness but might accumulate fatigue
Essential Marathon-Specific Advice
Nutrition and Fueling
- Practice your race-day nutrition strategy on long runs (16 km+)
- Aim for 30-60g of carbohydrates per hour during long runs
- Test different gels, chews, or real food to find what works for you
- Never try new nutrition on race day—only use what you've practiced
Hydration Strategy
- Drink to thirst during runs rather than forcing fluids
- Practice drinking on the move during long runs
- Know where water stations are located on your race course
- Consider electrolyte drinks for runs longer than 90 minutes
Long Run Execution
- Start conservatively—the first 30 minutes should feel ridiculously easy
- Break the run into manageable segments mentally
- Practice your race-day routine: wake time, breakfast, warm-up
- Use the final 10 km to practice mental toughness strategies
Recovery Practices
- Sleep is your most important recovery tool—prioritize it
- Fuel within 30 minutes after hard workouts (protein + carbs)
- Consider foam rolling, stretching, or yoga on rest days
- Ice baths and compression gear can help but aren't essential
Injury Prevention
- Address minor aches immediately—they become major injuries if ignored
- Incorporate strength training 2x per week (focus on glutes, core, hips)
- Replace running shoes every 500-800 km
- If something hurts during a run, stop—you can't "run through" injuries
Tracking Your Progress
Maintain a training log including:
- Daily mileage and workout type
- How you felt (energy, soreness, mood)
- Sleep quality and duration
- Weather conditions
- Any niggles or concerns
- Successful nutrition/hydration practices
This log helps identify patterns, track improvements, and inform future training.
Race Week (Week 16) Specifics
Monday-Thursday: Light, easy running with strides to maintain leg turnover Friday: Complete rest—no running Saturday: Optional 3 km shake-out jog or complete rest Sunday: Race day!
Race Day Tips:
- Start conservatively—aim for negative splits (second half faster than first)
- Stick to your practiced pacing and nutrition strategy
- The first 30 km should feel easy—the marathon starts at 32 km
- Break the race into segments: 0-15 km (settle in), 15-30 km (cruise), 30-42 km (dig deep)
- When it gets hard (and it will), focus on form, breathing, and the next kilometer
After Completing Your Marathon
Immediate Post-Race (1-2 weeks):
- Rest completely or do very light cross-training only
- Your body needs recovery—resist the urge to "shake out" your legs with runs
- Focus on sleep, gentle movement (walking), and good nutrition
Weeks 3-4 Post-Race:
- Begin easy running again (3-4 km at a time)
- No structured training—just run for enjoyment
- Listen carefully to your body
4+ Weeks Post-Race:
- You can begin structured training again if desired
- Consider what's next: another marathon, shorter distances, or maintenance running
- Use this time to address any weaknesses exposed during training
Mental Preparation
Marathon training is as much mental as physical:
- Weeks 1-10: Focus on consistency and building the habit
- Weeks 11-13: Embrace discomfort—you're doing hard things
- Weeks 14-16: Visualize success and trust your training
- Race Day: Remember why you started and enjoy the journey
Remember: Marathon training is a privilege. Not everyone has the health, time, or support to undertake this challenge. Respect the process, listen to your body, and celebrate every milestone.
The goal isn't just to finish the marathon—it's to reach the start line healthy, trained, and confident. The finish line will take care of itself.
