01 · Why 16 weeks?Why a 16-week plan?
The marathon (42.2 km) requires a longer build-up than shorter distances. You are not only developing endurance, but also the ability to hold marathon pace for a long time. This plan trains both your body and your fueling and recovery strategy, so you do not just reach the finish line, but actually enjoy the race.
02 · Who is this plan for?Who is this plan for?
This plan is designed for runners with a solid base who are ready for the next step. If you already have experience with longer distances and can train three times per week, this programme helps you move toward the marathon in a controlled and confident way.

03 · Marathon planMarathon running plan (16 weeks)
The marathon requires more than endurance alone. It also asks for structure and patience. To prepare responsibly for 42.2 km, this plan is split into three phases, each with its own training focus.
Foundation phase (weeks 1-6)
In the foundation phase, you build the base: easy mileage, endurance and resilience.
| Week | Session 1 (Monday) | Session 2 (Wednesday) | Session 3 (Saturday/Sunday) |
|---|---|---|---|
| 1 | Easy run 45 min | Interval 6 × 3 min strong, 90s recovery | Long run 80 min |
| 2 | Easy run 50 min | Interval 7 × 3 min strong | Long run 90 min |
| 3 | Easy run 50 min + 4 Strides | Interval 6 × 4 min brisk | Long run 100 min |
| 4 | Easy run 50 min | Tempo run 25 min | Long run 110 min |
| 5 | Easy run 45 min | Interval 6 × 5 min at 10K pace, 90s recovery | Long run 120 min |
| 6 | Easy run 50 min | Tempo run 30 min | Long run 130 min (optionally slightly faster in the final 10 min) |
Goal: build the base and increase load without forcing it.

Build phase (weeks 7-13)
The build phase raises the load further with longer long runs, tempos and fueling practice so your body and energy management get used to marathon demands.
| Week | Session 1 (Monday) | Session 2 (Wednesday) | Session 3 (Saturday/Sunday) |
|---|---|---|---|
| 7 | Easy run 50 min + strides | Interval 5 × 1 km strong, 2 min recovery | Long run 135 min |
| 8 | Easy run 50 min | Tempo run 35 min | Long run 140-145 min |
| 9 | Easy run 55 min | Interval 4 × 1200 m at 10K pace | Long run 150 min |
| 10 | Easy run 50 min | Tempo run 40 min | Long run 155-160 min (last 20 min at marathon pace) |
| 11 | Easy run 55 min | Interval 5 × 1 km at marathon pace | Long run 165-170 min |
| 12 | Easy run 50 min | Tempo run 45 min | Long run 180 min (including fueling practice with gels or sports drink) |
| 13 | Easy run 45 min | Interval 6 × 3 min brisk | Long run 150 min (recovery week) |
Goal: get used to marathon pace and practise fueling.

Taper phase (weeks 14-16)
Finally, the taper phase is there for recovery, freshness and confidence in the final weeks. You train less aggressively, but still keep your body awake so you feel sharp at the start.
| Week | Session 1 (Monday) | Session 2 (Wednesday) | Session 3 (Saturday/Sunday) |
|---|---|---|---|
| 14 | Easy run 45 min | Tempo run 25-30 min | Long run 120 min |
| 15 | Easy run 40 min | Interval 4 × 800 m at race pace | Long run 90 min (Taper) |
| 16 | Easy run 35 min | Easy run 25 min + 3 strides | Marathon race (42.195 km) |
Goal: arrive fresh at the start.
