How to use this marathon page
Earn the long runs
Long runs work best when weekly volume supports them. One huge Saturday does not make up for thin weekdays.
Train fueling early
Practice calories and fluids before the peak block. Marathon fitness is partly stomach training.
Keep pace work honest
Marathon-pace work should sit inside a recoverable week. If it wrecks the next two runs, it was too much.
Preview a marathon training week
The marathon week has to support the long run. One impressive Saturday does not make up for thin weekdays.
| Day | Focus | Purpose |
|---|---|---|
| Mon | Rest | Full rest or light mobility. |
| Tue | Marathon pace | 2 x 20 min around marathon effort inside an easy run. |
| Wed | Easy | 45-60 min comfortable aerobic running. |
| Thu | Medium long | 75-90 min easy. Keep the last third honest but controlled. |
| Fri | Rest | Recovery before long-run work. |
| Sat | Long run | 16-18 miles / 26-29 km with planned fuel and fluids. |
| Sun | Recovery | 30-45 min easy 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
