14-20 miles / 22-32 km
What matters for an intermediate marathon
Marathon pace belongs in context
Use marathon-pace work after the easy volume is stable, then keep the following day genuinely easy.
Watch the long-run share
A big long run only works if the rest of the week supports it. The plan should not be one hard day and filler.
Practice fueling repeatedly
Treat fueling as a weekly skill during longer runs, not a race-week reminder.

| Day | Focus | Purpose |
|---|---|---|
| Mon | Rest | Full rest or mobility |
| Tue | Quality | Marathon-pace or threshold blocks |
| Wed | Easy | Relaxed aerobic mileage |
| Thu | Medium long | Durable endurance run |
| Fri | Rest | Recovery day |
| Sat | Long run | Progressive distance and fueling practice |
| Sun | Recovery | Easy run or low-impact cross-training |
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
