Thinking about running 26.2 miles? Good call. This Marathon Training Guide walks you through the basics—why the plan matters, how to structure long runs and recovery, what to eat, and how to approach race day so you don’t bonk. I’ve coached weekend warriors and talked to coaches; from what I’ve seen, sensible progress and consistency beat miracle workouts every time. Read on for a practical training plan, pacing advice, injury prevention tips, and a race-day checklist you can actually use.
How to start a marathon training plan
Begin with a realistic assessment. Can you run 3 miles comfortably? 10? Your starting fitness drives the plan length. Most beginner programs run 16–20 weeks; intermediate runners often need 12–16 weeks to sharpen speed and pace.
Key steps to begin
- Set a clear goal: finish, time goal, or simply enjoy the race.
- Choose a training schedule that fits life—consistency matters more than intensity.
- Plan one long run, one tempo or threshold session, and easy runs each week.
- Build mileage gradually: follow the 10% rule (don’t increase weekly mileage more than ~10%).
Sample marathon training schedule for beginners and intermediate runners
Below is a compact comparison to help you pick a path. Use this as a template and tailor based on recovery and time.
| Week | Beginner (weeks 1–16) | Intermediate (weeks 1–12) |
|---|---|---|
| 1–4 | 3–4 runs, long run 6–10 mi | 4–5 runs, long run 10–14 mi |
| 5–8 | 4 runs, long run 10–14 mi | 5 runs, tempo + intervals, long run 14–18 mi |
| 9–12 | 4 runs, add race-pace segments, long run 14–18 mi | 5–6 runs, higher mileage, long run 16–20 mi |
| 13–16 | Peak long run 18–20 mi, then taper | Peak long run 20–22 mi, then taper |
Long runs, pace, and marathon pace strategy
Long runs are the backbone. They teach your body to burn fat, practice fueling, and build mental grit. I recommend a weekly long run that increases gradually. Every 3rd or 4th week, drop mileage for recovery.
How to use marathon pace
- Practice sections at marathon pace during long runs (e.g., last 6–8 miles at goal pace).
- Do tempo runs once a week to raise lactate threshold—these translate directly to a faster marathon pace.
- Race day: start slightly slower than goal pace for the first 5–6 miles, then settle in.
Tapering: when and how to reduce mileage
Tapering is where fitness meets freshness. Cut volume 20–30% two weeks out and 40–60% the final week. Keep intensity with short, brisk runs to stay sharp. Trust the taper—you’re not losing fitness; you’re letting your body recover.
Nutrition and fueling for marathon training
Nutrition wins races when training is solid. Plan daily nutrition and on-run fueling. Practice everything during training—don’t try new gels on race day.
Daily basics
- Carbs for volume: whole grains, fruit, potatoes.
- Protein for repair: lean meats, dairy, legumes—aim for 1.2–1.6 g/kg if training hard.
- Hydration: sip regularly; weigh yourself before/after long runs to estimate losses.
On-run fueling
- For runs 90+ minutes: 30–60 g carbs per hour (gels, chews, sports drink).
- Practice timing: take your first gel around 45–60 minutes into long runs.

Injury prevention and recovery
Most setbacks are avoidable. Load management, strength work, and sleep prevent many problems.
Practical steps
- Strength train twice weekly—hip, core, and single-leg work matters.
- Prioritize sleep: 7–9 hours for recovery and adaptation.
- Address niggles early—cut volume for 1–2 weeks rather than push through persistent pain.
Sample week (intermediate focus on marathon training plan)
Here’s a sample week that balances mileage and quality. Tweak it for your schedule.
- Mon: Easy 6 miles + strength
- Tue: Intervals (e.g., 6x800m) or tempo 5–6 mi
- Wed: Easy 6–8 miles
- Thu: Marathon pace run 8–10 miles
- Fri: Rest or easy 4 miles + mobility
- Sat: Easy 8–10 miles
- Sun: Long run 16–20 miles (build gradually)
Mental game and race-day checklist
Practice visualization and positive self-talk. Break the race into manageable chunks—miles 1–10, 10–18, 18–26.2. Plan pacing and fueling, and pack clothes and backups the night before. On race day, aim for steady effort, not ego-fueled speed.
Race-day essentials
- Race bib, safety pins, watch.
- Fuel (gels) and a small emergency snack.
- Socks and shoes you’ve logged many miles in.
- Layer for weather; know drop-bag locations.
Common mistakes I see
- Increasing mileage too quickly.
- Skipping recovery and ignoring sleep.
- Trying new shoes, fuels, or gear on race day.
- Starting the race too fast due to adrenaline.
Quick troubleshooting
Hit a plateau? Add strength work, vary workouts, and check recovery. Feeling tired for weeks? Back off volume 20% for a week and reassess.
Final nudge: Marathon training is a slow-build project. Be patient, track progress, and enjoy the small wins—your body adapts in unexpected ways if you give it time.

Frequently Asked Questions
Most beginner plans are 16–20 weeks; intermediate plans often run 12–16 weeks. Choose based on current fitness and weekly mileage.
Aim for 3–6 runs per week depending on experience. Include one long run, one quality session (tempo or intervals), and easy recovery runs.
Increase mileage gradually (about 10% per week), include strength training, prioritize sleep, and address pain early rather than pushing through it.
Start tapering 2–3 weeks before the race: reduce volume by ~20–30% in week two and 40–60% in the final week while keeping some short intensity.
For efforts over 90 minutes, consume 30–60 g of carbs per hour via gels, chews, or sports drink. Practice timing and brands during training.
