Before You Start
This plan is intended as a general reference and does not replace an individualized training program. Mileage, intensity, recovery and progression should be adapted to the athlete’s starting level, training history and goals.
The 16-week program assumes an established running base and is not intended for runners returning from a long period of inactivity.
Marathon preparation requires a progressive approach in which training volume, intensity and recovery are combined and managed in a balanced way.

Weekly Training Structure
Weeks 1-4: Building the Base
The first part of the preparation focuses on establishing consistency and preparing the body for the training loads to come.
Sessions may include:
- easy running, to develop the aerobic base;
- running technique and mobility work, to improve movement efficiency;
- moderate quality sessions, such as fartlek or short intervals;
- a progressive long run, gradually increasing the time spent running.
At this stage, there is no need to constantly chase race pace. The goal is to build a solid enough foundation to handle the following weeks.
Weeks 5-8: Increasing Volume
Once the base has been established, the training can gradually become more demanding.
Weekly volume increases and long runs become increasingly important.
Training may include:
- medium-length intervals;
- structured fartlek sessions;
- controlled tempo runs;
- longer runs;
- functional strength and core stability work.
The goal is to develop a greater ability to handle training load without turning every session into a maximal effort.
Progression should be gradual: it is not a single workout that builds a marathon, but the consistency of many weeks of well-managed training.
Weeks 9-12: Intensifying the Preparation
This is the stage where training begins to more closely reflect the demands of the race.
Individual marathon pace can be introduced into specific workouts, alternating it with easier running.
Long runs also take on a central role.
The goal is not simply to reach a certain distance: some long runs may include pace variations or sections at race pace, helping the body maintain good efficiency as fatigue increases.
This is also an ideal stage to test:
- race strategy;
- fueling during the run;
- hydration;
- clothing;
- shoes;
- pace management.
You prepare for a marathon by learning how to manage what happens during the marathon.
Weeks 13-15: Tapering
During the final weeks, training volume is gradually reduced.
Tapering does not mean stopping running. It means reducing the training load to allow the body to recover and arrive at race day in the best possible condition.
Training sessions generally become shorter while maintaining some intensity to keep the body responsive.
This is also a phase in which the athlete needs to manage the mental side of training: doing less can sometimes create the feeling of not being sufficiently prepared.
In reality, arriving at the starting line fresh is an integral part of marathon preparation.
Week 16: Race Week
The goal of the final week is not to improve fitness.
The work has already been done.
Runs become short and controlled, with plenty of focus on recovery and race preparation.
This is the time to focus on:
- recovery;
- sleep;
- nutrition and hydration;
- race-day logistics;
- pacing strategy;
- managing the opening kilometres.
A marathon requires, above all, the ability to manage effort. Starting in a controlled way and sticking to your strategy can be crucial to handling the second half of the race effectively.
Final Tips
- Do not increase training volume too quickly.
- Do not turn every workout into a race.
- Give long runs the attention they deserve without always running them hard.
- Include strength, mobility and running technique in your preparation.
- Test your fueling and hydration strategy before race day.
- Consider recovery part of your training.
- Learn to listen to your body’s responses.
