The Complete Marathon Training Plan Guide: From Half Marathon to Full Marathon
The marathon (42.195 km) is the classic endurance sports challenge. Whether your goal is to finish or to set a new PB, a well-structured training plan is the key to success. This article provides a step-by-step progression from half marathon entry to full marathon advanced training, with specific weekly mileage, long run strategies, and taper planning.
Prerequisites: Are You Ready?
Before starting marathon training, it is recommended that you have the following foundation:
| Goal | Recommended Foundation |
|---|---|
| Half Marathon (21.1K) | Can comfortably run 10K, with a stable weekly mileage of 20-25K for 4+ weeks |
| Full Marathon (42.195K) | Have completed at least one half marathon, with a stable weekly mileage of 30-40K for 8+ weeks |
Half Marathon Training Plan (12 Weeks)
Suitable for: Runners who can complete a 10K and want to take on the challenge of their first half marathon.
Training Structure
4-5 training sessions per week, including:
- Easy runs 2-3 times: Zone 2 heart rate, building aerobic base
- Quality workout 1 time: Tempo run or interval training
- Long run 1 time: Done on Sundays, this is the focus of the training week
12-Week Plan Overview
| Week | Weekly Mileage (km) | Long Run Distance | Quality Workout |
|---|---|---|---|
| 1 | 25 | 10K | Tempo run 15 min |
| 2 | 28 | 11K | Intervals 800m × 4 |
| 3 | 30 | 13K | Tempo run 20 min |
| 4 | 25 (Recovery week) | 10K | Easy run |
| 5 | 32 | 14K | Intervals 1000m × 4 |
| 6 | 35 | 16K | Tempo run 25 min |
| 7 | 37 | 17K | Intervals 1200m × 4 |
| 8 | 30 (Recovery week) | 12K | Easy run |
| 9 | 38 | 18K | Tempo run 30 min |
| 10 | 40 | 20K | Intervals 1000m × 5 |
| 11 | 30 (Taper week) | 14K | Tempo run 15 min |
| 12 | 20 (Race week) | Race day 21.1K | Easy run 3K 2 days before race |
Long Run Pace Recommendations
Long run training pace should be 30-60 seconds/km slower than your target race pace:
| Half Marathon Target Time | Race Pace | Long Run Training Pace |
|---|---|---|
| 2:30:00 | 7:06/km | 7:40-8:00/km |
| 2:00:00 | 5:41/km | 6:15-6:40/km |
| 1:45:00 | 4:58/km | 5:30-6:00/km |
| 1:30:00 | 4:16/km | 4:45-5:15/km |
Full Marathon Training Plan (16 Weeks)
Suitable for: Runners who have completed a half marathon and want to take on the full marathon or break their full marathon PB.
Training Structure
5-6 training sessions per week:
- Easy runs 3-4 times: Zone 2 heart rate
- Quality workout 1 time: Intervals or tempo run
- Long run 1 time: Progressively increasing to 32-35K
16-Week Plan Overview
| Phase | Weeks | Weekly Mileage | Long Run Distance | Focus |
|---|---|---|---|---|
| Base Phase | 1-4 | 40→50K | 16→22K | Build mileage base |
| Development Phase | 5-8 | 50→60K | 22→28K | Add quality workouts |
| Peak Phase | 9-12 | 60→70K | 28→35K | Highest mileage period |
| Taper Phase | 13-16 | 55→35K | 25→Race | Gradual recovery, store energy |
Key Workout: Marathon Pace Run (MP Run)
During the peak phase (weeks 9-12), incorporate marathon pace segments into your long runs:
- Week 9: Long run 28K, with the final 8K at MP
- Week 10: Long run 30K, with the middle 12K at MP
- Week 11: Long run 32-35K, with the final 15K at MP
- Week 12: Long run 25K (recovery), all in Zone 2
The Science of Hitting the Wall and How to Counter It
The most famous challenge of the marathon is “Hitting the Wall,” which typically occurs at 30-35 kilometers. The cause is glycogen depletion, forcing the body to rely heavily on fat for fuel, but fat oxidation rates are far lower than those of glycogen.
Prevention Strategies:
- Long runs exceeding 30K: Let your body adapt to the feeling of glycogen depletion
- Improve fat oxidation capacity: Plenty of Zone 2 training
- Race day fueling strategy: Consume 30-60g of carbohydrates every 30-45 minutes (energy gels, sports drinks)
- Carbohydrate loading: Increase carbohydrate intake to 8-10g per kg of body weight in the 3 days before the race
Taper Strategy
The taper is the critical period 2-3 weeks before the race where you gradually reduce training volume to allow full recovery and complete glycogen replenishment.
Half Marathon Taper (2 Weeks)
| Week | Mileage Reduction | Intensity |
|---|---|---|
| 2 weeks before race | Reduce to 70% of peak mileage | Maintain 1 short interval session |
| 1 week before race | Reduce to 50% of peak mileage | Easy runs only + short stride session 2 days before race |
Full Marathon Taper (3 Weeks)
| Week | Mileage Reduction | Intensity |
|---|---|---|
| 3 weeks before race | Reduce to 75% of peak mileage | Maintain 1 tempo run |
| 2 weeks before race | Reduce to 55% of peak mileage | Short intervals to maintain leg speed |
| 1 week before race | Reduce to 35% of peak mileage | Easy runs primarily, 3K with 4 × 100m strides 2 days before race |
Common Taper Myth: “Will tapering make me lose fitness?” No. Research shows that an appropriate taper can improve race performance by 2-3% (Mujika & Padilla, 2003), because the benefits of muscle repair, glycogen supercompensation, and nervous system recovery far outweigh the temporary fitness loss from reduced training.

Race Day Strategy
Pacing Strategy
- Negative Split: Run the first half 1-2 minutes slower than the second half; this is the most reliable strategy
- Even Split: Maintain the same pace throughout; suitable for experienced runners
- Absolutely Avoid a Positive Split: Going out too fast in the first half is the most common mistake among beginners
Fueling Schedule
| Time Point | Fueling Content |
|---|---|
| 2 hours before start | Low-fiber carbohydrate breakfast (white toast, banana, energy bar) |
| Every 30 minutes | 1 energy gel (approx. 25g carbs) + water |
| Every aid station | 3-4 sips of water or sports drink |
| After 25K | Consider adding a caffeinated energy gel |
Conclusion
Marathon training is a test of patience lasting 16 weeks (or even longer). Follow the plan, respect your body’s signals, and slow down when you should—you are already on the right path to the finish line. Remember: Being able to stand healthy at the starting line means you are already halfway to success.
