Sample · Sub-3:30 Marathon · 21-week plan

Welcome back, Client. Keep moving.

A full 21-week build to a sub-3:30 marathon — every run, strength session, and recovery day, base through race day. The Today button always lands on today\'s session.

Logging daily is what makes the weekly tune-ups sharp — the more honest data in, the better the plan out. Your data is private. We never sell it, ever.

This is a sample plan.

It shows how a sub-3:30 marathon build looks inside Elite Metabolix — a week-by-week calendar, tappable sessions, exercise demos with form cues, a plain-language glossary, and a 30-second daily check-in. Your real plan is built around your goal, schedule, history, and how you respond week to week. Apply to get yours →

Coaching, not medical care.

Elite Metabolix covers training, fueling, and recovery only. Anything medical — pain, injury, bloodwork, medication — stays with your physician or another licensed provider. Never run through pain; when in doubt, get it checked.

The Plan · Week by Week

21 weeks to race day.

A balanced week — quality midweek, long run on the weekend, easy running and lower-leg strength around them — from base through race day. Volume climbs gradually with a planned down week every 3–4 weeks, because steady beats heroic in a marathon build. Tap a week, then any day.

Nutrition · Built around you

Why your plan looks the way it does.

Fueling for a marathon comes down to three things: eating mostly whole foods day to day, getting enough protein to stay durable, and timing carbohydrate around the running. This is the reasoning, not a rigid diet.

Everyday base

Whole-food by default

The everyday plate leans Mediterranean: more fiber and whole grains, fish and plants, olive oil over butter, fewer refined-carb and fried foods. It's a habit, not a restriction. (Anything medical — bloodwork or medication — stays entirely with your physician; we don't touch those.)

Frame

Protein for durability

A bigger runner has higher absolute needs and more tendon load per stride. Protein stays high (~1.8–2.0 g/kg, roughly 165–185 g/day) to protect muscle and support connective-tissue repair through a heavy build.

Goal

Fuel the marathon

Carbohydrate is the fuel for long miles. We periodize it — more on long-run and quality days, less on easy and rest days — so the tank is full when the work demands it. Eat enough to train well; under-fueling a marathon build is how injuries and stalls happen.

Carbohydrate, by day type

Long-run / quality dayshigher — top the tank the day before & fuel mid-run
Easy run / strength daysmoderate — around the session
Rest dayslower — protein and veg lead the plate

Anchor carbs around the running; pull them back on rest days. Protein and the whole-food base hold steady all week. On long runs over ~75 min, practice taking carbs every 30–40 min so race-day fueling is rehearsed.

Simple swaps

  • White rice → brown rice / quinoa
  • Refined bread → whole-grain / sourdough
  • Fried snacks → roasted chickpeas, nuts
  • Red/processed meat → fish, chicken, beans, tofu
  • Cook with → olive oil, lighter on butter

A training day, reasonably

  • ~7aBreakfast — oats, berries, walnuts + eggs or yogurt
  • ~12:30pLunch — salmon or chicken + brown rice + veg
  • ~5:30pPre-run — banana or toast, coffee if needed
  • post-runRecovery — protein + carbs within ~45 min, then dinner
Quick reference · fueling

Timing it around your day and the long run

  • Front-load the dayA real breakfast and lunch fuel your afternoon and evening sessions far better than back-loading calories late. Eat enough during the workday that you're not running on empty after 5pm.
  • Pre-run top-upAbout 60–90 minutes before an evening run, have a small, mostly-carb snack — a banana, toast, or a couple of dates. Steady energy without sitting heavy.
  • Spread protein evenlyRoughly 30–40 g at each of four meals beats one big serving. Even feeding supports muscle and connective-tissue repair across the day — which matters more across a heavy training block.
  • Cross-training / sport daysIf you add a hard cross-training session or a sport, eat a proper meal and a light carb snack beforehand and rehydrate after. It's a real load on the legs — fuel it like one.
  • Long-run mornings (Sat)Easy carbs 1–2 hours before, fuel every 30–40 minutes once you pass ~75 minutes, and refuel with protein + carbs within ~45 minutes of finishing. This is your race-day rehearsal — practise it now.

Built to complement your medical care.

Training, fueling, and recovery only — no diagnosis, no lab interpretation, no medical management. Bloodwork, any injury or medical condition, and any medication or supplement decisions stay with your physician, sports-medicine doctor, registered dietitian, or PT. If their guidance and this plan ever disagree, theirs wins.

Strength · Tap any exercise

Strength that protects the miles.

Tap any exercise for sets, a live tempo animation, and exactly how to perform it — plus an optional video demo a tap away. Calf and lower-leg work is the durability anchor; the bigger lifts build the strength to hold pace late. Keep every rep pain-free, and let your PT set anything injury-specific.
