Race Week Nutrition for a Controlled Start

The work is done. Most of your fitness has already been built, and the final seven days are not the moment to chase it with a hard session, a restrictive diet or a new supplement. Race week nutrition has one job: protect the training adaptation, restore glycogen, arrive well hydrated and make race-day decisions automatic.

For endurance athletes, poor execution usually comes from small errors compounded over several days. Skipping meals while travelling, under-drinking because training volume has dropped, eating a restaurant meal that does not agree with you, or waiting until the start gun to think about carbohydrates can all turn a strong build into a difficult race. The answer is not a perfect menu. It is a clear, repeatable protocol.

Race Week Nutrition Starts With Reduced Training

As volume falls, appetite often falls with it. That is normal, but it can create a problem: your carbohydrate requirement remains high enough to replenish muscle glycogen, even though your usual training hunger is gone. Do not use taper week to cut carbohydrates simply because your watch shows fewer kilometres.

For most of the week, keep meals familiar and structured. Base them around carbohydrate-rich foods you tolerate well, alongside normal portions of protein, fruit and vegetables, and fats that do not make meals excessively heavy. Rice, pasta, potatoes, oats, bread, cereal, yoghurt and fruit all work. The best choice is the one you have used successfully in training.

A useful baseline for athletes tapering for an endurance event is roughly 5-7 g of carbohydrate per kilogram of body mass per day. This is not a target to force down at every meal. It is a practical range that helps maintain glycogen while training load decreases. A 70 kg athlete, for example, may need around 350-490 g across the day, spread through meals and snacks rather than crammed into one oversized dinner.

Keep protein consistent, generally around 1.6-2.0 g per kilogram per day, particularly if you are managing a long season, a calorie deficit, or heavy travel demands. Protein supports repair and helps keep meals satisfying. It is not, however, the nutrient that fuels race intensity. Carbohydrate remains the priority as the event approaches.

The Final 48 Hours: Load With Purpose

Carbohydrate loading is most valuable for events lasting longer than about 90 minutes, including a marathon, long-distance triathlon, demanding sportive or a hard trail race. For shorter races, an aggressive load is rarely necessary and may leave you feeling overly full. You still need to arrive fuelled, but the dose should match the duration and intensity of the event.

For longer events, the final 24-48 hours can call for 7-10 g of carbohydrate per kilogram of body mass per day. The higher end is useful when the race will be long, the course is demanding, or you have a history of fading late despite solid in-race fuelling. It also depends on what your gut can comfortably handle. More is not automatically better if it creates bloating, disrupted sleep or anxiety around food.

Make the load easier by choosing lower-fibre, lower-fat versions of foods you already trust. Swap a large bean-based meal for rice or pasta. Choose white toast, bagels or cereal if wholegrains cause digestive bulk. Keep vegetables in sensible portions rather than trying to maximise fibre the night before a race. This is not a verdict on food quality. It is a short-term performance decision designed to reduce gastrointestinal risk.

Do not turn the night-before meal into a ceremony. One large pasta dinner cannot rescue an under-fuelled week. Eat a familiar carbohydrate-led evening meal, stop before you are uncomfortably full, and prepare the next morning's breakfast before you go to bed. Calm logistics are part of performance nutrition.

Hydration Is Not Just Drinking More Water

The aim in race week is euhydration: arriving normally hydrated, not trying to dilute your system with litres of plain water. Pale straw-coloured urine across the day is a useful broad indicator, but it is not a command to chase completely clear urine. Excessive water intake without sodium can leave you feeling flat, increase toilet stops and, in severe cases, create a genuine health risk.

Start with regular fluid intake at meals and between meals, then adjust for heat, travel, dry hotel air, altitude and any remaining training sessions. Include electrolytes when sweat losses are high, when conditions are warm, or when you know you are a salty sweater. Sodium is the primary electrolyte to plan around because it supports fluid retention and replaces the main mineral lost in sweat. Potassium and magnesium also have physiological roles, but they do not replace a sound sodium strategy.

Your personal sweat rate matters. An athlete racing in cool conditions for 90 minutes needs a different plan from an athlete spending six hours in summer heat. If you have previously measured your sweat rate or noticed salt marks on kit, use that information. If not, keep the plan conservative and practise it. Race week is the wrong time to copy the sodium intake of a professional athlete with a different body size, pace and environment.

Keep the Gut Quiet, Not Empty

Gastrointestinal distress is often blamed on gels, when the real cause is a combination of high intensity, dehydration, fibre overload, unfamiliar food and poor timing. The final two days are about reducing variables.

Avoid experiments. Do not add a new probiotic, high-dose caffeine product, spicy takeaway, alcohol-heavy celebration or unfamiliar recovery drink because someone at the expo recommended it. If you have a diagnosed gut condition, coeliac disease, diabetes, or a history of significant GI symptoms, build the plan with a registered sports dietitian or clinician rather than relying on generic race advice.

Caffeine deserves the same discipline. It can improve endurance performance for many athletes, but only when the dose and timing have been tested. If you normally take it, use your proven protocol. If you do not, race week is not the time to find out whether it gives you focus or sends you searching for a toilet.

Rehearse Race Morning Before It Matters

Your pre-race meal should be familiar, carbohydrate-led and timed to allow digestion. For many athletes, eating 1-4 g of carbohydrate per kilogram of body mass in the one to four hours before the start works well. The exact amount depends on start time, nerves, travel to the venue and how much food you can tolerate.

An early marathon start may mean a light breakfast three hours beforehand, followed by a small carbohydrate top-up closer to the gun. An afternoon triathlon gives you more time to eat a substantial breakfast and a controlled pre-start snack. Neither approach is inherently better. What matters is that you have practised it under comparable conditions.

Pack this food yourself where possible. Hotels run out of bread, cafes open late and queues grow quickly on race mornings. Bring the breakfast, the bottle, the electrolytes and the fuel you will use during the event. Check bag-drop rules, bottle availability and aid-station products in advance. A precise plan is worthless if the products are in your hotel room.

Build the In-Race Plan Before the Taper

The race does not begin when hunger appears. By then, you may already be behind. Your in-race carbohydrate plan should be based on duration and intensity, then rehearsed in long sessions. Many endurance athletes perform well on 60-90 g of carbohydrate per hour. For very long, high-output events, athletes who have trained their gut may tolerate up to 90-120 g per hour using multiple transportable carbohydrates.

Start early, take small doses consistently and pair the plan with fluid and sodium appropriate to the conditions. This is where a system earns its place: fuel for carbohydrate delivery, electrolytes for hydration management, and an intake schedule simple enough to follow when concentration drops. truefuels is built around that principle - measured inputs, tested in real endurance conditions, rather than improvisation.

Write the plan down in actual timings. For example, decide what you will take in the first 20 minutes, at each hour, and at known points on the course. Include a contingency for heat, a missed bottle or a delayed feed station. You do not need to be rigid when conditions change, but you do need a starting framework.

The Day Before: Protect Energy and Attention

Keep moving lightly if your programme calls for it, but do not spend the day wandering an expo, standing in queues or turning travel into a stress test. Eat regularly. Drink steadily. Put your race nutrition into separate, clearly labelled portions. Charge devices, check weather, lay out kit and then stop making decisions.

A good race week does not feel dramatic. It feels controlled. You arrive at the line with glycogen stores supported, hydration managed, your stomach settled and every feed already accounted for. That is not luck. It is the final, disciplined part of training.
