What matters for a sub-4 marathon

Know the pace

Sub-4 is 5:41/km or 9:09/mile. It should feel manageable in controlled blocks, not heroic in February.

Build long-run durability

The goal is not one impressive long run. It is several weeks where the long run fits inside the whole week.

Fuel like it is training

Use long runs to rehearse calories, fluids, and timing. A sub-4 attempt leaves little room for guessing.

Preview a sub-4 marathon week

Sub-4 is about holding 5:41/km or 9:09/mi when tired. The week should build that rhythm without making every run a race.

Which level should you choose?

Beginner

Use this if the main job is getting to the start line healthy, with long runs and fueling practice built slowly.

Intermediate

Use this if you already run consistently and want a marathon block with steady volume and marathon-pace work.

Advanced

Use this if you have marathon experience and can absorb bigger weeks without forcing recovery.

How long should the plan be?

12 weeks

Only makes sense if you already have a solid base and recent long runs.

16 weeks

The standard choice for many marathoners because it balances build, peak, and taper.

18-20 weeks

Better for first marathons, comeback blocks, or runners who need more time to build long-run durability.

Common mistakes to avoid

  • Building the long run faster than weekly volume supports
  • Practicing fueling too late in the training block
  • Running marathon-pace workouts while carrying too much fatigue
