The week before a marathon is one of the most psychologically challenging periods in the entire training cycle. Your mileage drops sharply, your legs feel strange, and a voice in your head insists you have not done enough. This is taper madness, and it is completely normal. The runners who navigate this week well — running little, resting deliberately, eating well, and staying calm — consistently outperform their fitness predictions. The runners who panic and add last-minute miles consistently underperform.
Day-by-Day Guide: Marathon Week
The following schedule assumes a Sunday race. Adjust the days forward or backward by one day for a Saturday race.
| Day | Running | Key Focus |
|---|---|---|
| Sunday (7 days out) | 30–40 min easy + 4–6 × 20 sec strides | Last quality stimulus, legs feel sluggish — normal |
| Monday | Rest or 20 min very easy | Full recovery, stay off feet |
| Tuesday | 25–35 min easy + 4 × 20 sec strides | Keep legs turning over, no effort |
| Wednesday | 20–30 min easy | Begin carbohydrate loading |
| Thursday | 20 min easy + 4 × 20 sec strides | Race prep: check kit, plan logistics |
| Friday | 15–20 min very easy | Rest, hydrate, finalise race plan |
| Saturday | 10–15 min very easy + 2–3 strides | Last shakeout, sleep early |
| Sunday | RACE DAY | Execute your plan |
Nutrition in Marathon Week
Carbohydrate loading — deliberately increasing carbohydrate intake to maximise glycogen stores — is the most impactful nutritional intervention of the week. Begin carb-loading on Wednesday or Thursday, not on Saturday. Your muscles need 48–72 hours to fully saturate glycogen stores, and cramming on the night before rarely works and often causes GI distress on race morning.
Target approximately 8–10 grams of carbohydrate per kilogram of body weight per day from Wednesday through Friday. For a 70kg runner, that is 560–700 grams of carbohydrate daily — significantly more than most runners eat normally. Focus on familiar, easily digested sources: rice, pasta, bread, potatoes, oats, bananas. Reduce fibre intake from Thursday to minimise GI risk on race day.
Avoid introducing new foods, supplements, or restaurants this week. Race morning is not the day to experiment with a new gel flavour or a restaurant you have never tried.
Taper madness is real: Most runners experience some combination of heavy legs, phantom niggles, low energy, and anxiety during taper week. These are normal physiological and psychological responses to reduced training, not signs of illness or inadequate preparation. Your body is using the reduced load to store glycogen and repair tissue — the process causes temporary sensations that feel alarming but are actually signs the taper is working.
Sleep and Rest
Sleep is the most underrated performance factor in marathon week. Two nights before race day matters more than the night immediately before. Most runners sleep poorly the night before a big race — nerves, early alarms, unfamiliar hotel rooms — and the sleep debt from Saturday cannot be repaid by Sunday morning. Bank sleep on Wednesday, Thursday, and Friday instead.
Stay off your feet as much as possible from Thursday onwards. If you are travelling to a race, arrive by Thursday at the latest. Spending Friday and Saturday walking around the race expo or sightseeing will add significant fatigue. The expo is exciting but an hour of purposeful movement through a crowded convention centre is more taxing than it appears.

Should I do any hard running in the week before a marathon?
No sustained hard efforts. Short strides (20 seconds at 5K effort with full recovery) two or three times during the week are beneficial — they maintain neuromuscular sharpness without creating fatigue. Nothing longer or harder than that. The fitness you need is already built; you cannot add more in a week, but you can certainly destroy it.
Is it normal to feel terrible during taper week?
Yes. Heavy legs, low energy, unusual aches, and anxiety are collectively called "taper madness" and affect the majority of marathon runners. These sensations typically resolve in the 48 hours before race day. The heaviness you feel during taper week is your muscles storing glycogen — a physical process that creates temporary discomfort but leaves you better prepared for race day.
How much water should I drink in marathon week?
Aim for pale yellow urine — a practical hydration indicator. Do not over-drink plain water, especially in the final 48 hours; hyponatremia (dangerously low sodium from excessive plain water intake) is a real risk for runners who aggressively over-hydrate. Include electrolytes (sports drink, electrolyte tablets, or salty foods) alongside your water intake.
What should I eat for breakfast on race morning?
Whatever you have practised in training. Race morning is the worst possible time to experiment. A typical effective pre-race breakfast 2–3 hours before the gun: 60–90 grams of carbohydrate from familiar sources (oatmeal, toast, banana, white rice), moderate protein, minimal fibre and fat. Eat early enough that digestion is complete before you start running.
Final Thoughts
week before marathon what to do is one of the most evidence-backed ways to improve your running performance. The techniques and principles here — spanning Day-by-Day Guide: Marathon Week, Nutrition in Marathon Week — give you everything you need to train smarter rather than just harder.
The biggest gains come from consistent, progressive application over weeks and months — not from any single workout. Use this guide as your starting framework, track your results honestly, and adjust based on what your body tells you.
