Marathon training plan

The marathon is not run, it is prepared. 42,195 km requires endurance built patiently and rigorous pace management. Here is the essence of successful preparation.

How much preparation time?

With a base of regular running, count on 12 to 16 weeks of specific training. If you are starting long-distance running, give yourself more time to build volume without getting injured. A marathon cannot be improvised over a few weeks.

The long run: the queen session

It is the cornerstone of marathon preparation. It increases progressively (up to ~28-32 km depending on level) and conditions the body — and the mind — to last. Run it at easy endurance pace, sometimes with portions at marathon pace towards the end of the run to get into your target rhythm.

Know your marathon pace

The fatal mistake: starting too fast. Determine a realistic pace (based on your 10 km/half marathon times) and train to hold it. On race day, the first kilometers should feel too easy — that is the good sign.

Structure your week

• 1 long run (on the weekend).
• 1 quality session (threshold, or intervals at marathon pace).
• 1-2 easy runs at endurance pace.
• The rest: recovery. ~80% of volume should remain easy.

Don't neglect tapering and nutrition

In the last 2-3 weeks, reduce volume to arrive fresh (tapering guide). And work out your fueling strategy during training: on a marathon, hitting the "wall" is often a matter of carbohydrates (nutrition guide).
