Plan length
16 weeks
Built with phases, cutbacks, and a taper you can actually execute.
Weekly rhythm
4–6 days/week
Choose one variant and follow it for 2 weeks before tweaking.
Typical session time
Easy: ~45m • Long: ~150m
Prefer consistent minutes over heroic single sessions.
Readiness gate
- • You can run 30 minutes comfortably 3–4×/week.
- • You can complete a long-ish session (60–75 min) without being wrecked for 2 days.
- • You’re willing to keep easy days easy so workouts stay high-quality.
Default recommendation
4 days/week (Beginner-friendly)
Start here to reduce decision fatigue. Customize only after your first two weeks feel stable.
- • Best if your schedule is tight or you’re building durability.
- • Keep workouts conservative; consistency is the win.
Safety first
This is general training information, not medical advice.
- • Pain that changes your gait (scale down and get assessed).
- • A rapidly increasing injury history with volume increases.
- • Illness symptoms that worsen with training load.

Workout library
The sessions you repeat
You don’t need 50 workouts. You need a small library that you execute consistently, then progress safely.
Easy aerobic run
Purpose: Build volume without accumulating fatigue.
Prescription: 30–60 min at conversational effort. If you can’t talk in full sentences, it’s too hard.
Substitutions
- • Bike or easy elliptical for the same time if impact is an issue.
Red flags
- • Pain that changes your gait.
- • Easy pace drifting harder to hold the same effort.
Strides + drills
Purpose: Improve mechanics and economy without a heavy metabolic cost.
Prescription: After an easy run: 6–10 × 15–20 sec fast-but-relaxed, full walk/jog recovery.
Substitutions
- • 6–8 × 20 sec hill strides for reduced impact.
Red flags
- • Sprint-like intensity that leaves you sore.
- • Tight hamstrings or sharp calf pain.
Tempo / cruise intervals
Purpose: Raise sustainable pace and teach controlled discomfort.
Prescription: 2–4 × 8–12 min at ‘comfortably hard’ with 2–3 min easy between.
Substitutions
- • 20–30 min steady tempo continuous if you pace well.
Red flags
- • Breathing out of control early.
- • Needing to ‘surge’ to hold the last reps.
Interval session (VO₂-ish)
Purpose: Sharpen speed and economy for faster running at a lower cost.
Prescription: 5–8 × 3 min hard with 2–3 min easy; stay controlled, finish with form.
Substitutions
- • 6–10 × 400m on the track with equal jog recovery.
Red flags
- • All-out reps.
- • Form collapse or sharp pains.
Long run (easy with structure)
Purpose: Build durability and rehearsals for race-day pacing and fueling.
Prescription: Mostly easy. When stable: add 2–6 × 10 min steady, and practice fuel + fluids.
Substitutions
- • Split long run (AM/PM) on high-stress weeks; keep total time similar.
Red flags
- • Long-run pace creeping; next-day fatigue lasting >48h.
- • Fueling causing repeated GI issues (adjust and practice).
Marathon-pace blocks
Purpose: Practice the exact intensity you want to execute on race day.
Prescription: 2–3 × 4–6 km at marathon effort inside a medium-long run; stay controlled.
Substitutions
- • Progression run: easy → steady → controlled hard (only when recovered).
Red flags
- • Needing to ‘push’ early.
- • Shin/calf pain that escalates with pace.
Strength (short + consistent)
Purpose: Support durability and running economy with minimal interference.
Prescription: 2×/week, 20–35 min: hips, calves, hamstrings, trunk. Leave 1–2 reps in the tank.
Substitutions
- • Bodyweight circuit if you’re traveling.
Red flags
- • Heavy DOMS that ruins key sessions.
- • Form breakdown under load.
Adaptation rules
What to do when life happens
Most training failures are not fitness failures — they’re pacing, sleep, or scheduling failures. Use simple rules.
Missed workout
- • Don’t ‘make up’ missed sessions by doubling hard days.
- • If you miss one workout: keep the long run, skip the extra intensity.
- • If you miss a week: repeat the last week you completed confidently.
Low sleep week
- • Cut intensity before you cut easy volume: keep it aerobic.
- • Shorten the long run by 15–25% if sleep is poor for multiple nights.
- • Add one extra rest day if stress is high.
Fatigue signals
- • If your easy pace feels hard: keep the day easy and shorten duration.
- • If soreness persists >48h: remove the next hard session.
- • If motivation tanks + HR drifts: treat it like a recovery week.
Pain or injury
- • Pain that changes form is a stop signal — do not ‘push through’.
- • Swap running for low-impact cardio until pain-free in daily life.
- • Return with short easy runs; add intensity last.
Travel week
- • Protect one key session: either the long run or the workout — not both.
- • Use time-based training (minutes) when terrain/schedule changes.
- • Keep strength micro-sessions (10–15 min) instead of skipping completely.

Planner
Marathon fueling schedule
A simple, repeatable plan: pick a carb target, then schedule doses you can actually execute while running.
Total time
Total carbs
Approx gels
Simple schedule
Take a dose every 20 minutes. In training, practice the same timing so race day is automatic.
Safety note: fueling targets vary by athlete and conditions. Practice in training and adjust if you get GI distress. This is not medical advice.
Evidence (high level)
Why this structure works
- • Consistency beats hero sessions: durable aerobic volume is the engine.
- • Cutback weeks reduce injury risk and help you absorb training.
- • A small workout library repeated with progression is more effective than endless novelty.
- • Fueling practice is a skill — you train it like pacing.
FAQs
Is a 16-week marathon plan enough time?
It can work if you already have a base. If you’re starting from scratch, extend the timeline and prioritize consistency over intensity.
How many hard sessions should I do per week?
A good default is one quality workout plus one long-run focus. If you add more, it should be short and only when recovery is stable.
What if I miss a run?
Don’t cram. Keep the next session easy, protect the long run, and resume structure when your legs feel normal again.
How do I keep easy runs truly easy?
Use a conversational effort check: you should be able to talk in full sentences. If not, slow down or add walk breaks.
Do I need strength training?
Two short sessions per week is a high-ROI habit for durability. Keep it consistent and avoid leaving yourself sore for key runs.
When should I practice fueling?
Start early in the build. Practice the exact products and timing you’ll use on race day, and adjust if you get GI issues.
