Race week is not the time to experiment
As nearly 69,000 runners prepare to take to Mumbai's streets for the Tata Mumbai Marathon, the question of what fuels human endurance reveals itself to be less about ambition and more about restraint. Sports nutritionist Sameera Sheikh offers a quiet but powerful reminder: the body performs best not when surprised, but when trusted with the familiar. In the hours before and after a race, the ancient wisdom of moderation proves more powerful than any novelty.
- Tens of thousands of runners risk undermining weeks of training in the final hours before the race through poor food choices — a single bad meal can unravel months of preparation.
- The temptation to overeat or experiment with new foods during race week is a common and costly trap, with oily, spicy, or high-fibre foods threatening digestive distress at the worst possible moment.
- Sheikh's guidance cuts through the noise: carbohydrate-load with known, gut-friendly staples like khichdi, roti, and boiled potatoes, and eat a light, familiar meal three to four hours before the starting gun.
- The post-race window of thirty to sixty minutes is a critical biological opportunity — muscles are primed to absorb nutrients, making a swift combination of carbs, protein, and fluids essential to recovery.
- Alcohol, excess caffeine, heavy meals, and untested energy products are flagged as performance saboteurs, with dehydration and digestive failure the most immediate risks on race day.
Nearly 69,000 runners are set to take over Mumbai's streets on January 18 for the Tata Mumbai Marathon, one of India's largest running events. For most participants, the outcome will hinge not just on training, but on the quiet decisions made around the dining table in the hours before and after the race.
Sameera Sheikh, a microbiologist and sports nutritionist with eleven years of experience, has watched countless runners undermine their own efforts through poor race-day nutrition. Her core principle is almost counterintuitive: eat boring food. Muscles run on stored carbohydrates, and the best way to protect that fuel supply is to stick strictly to what the body already knows.
In the days before the marathon, Sheikh recommends carbohydrate-rich staples — brown rice, khichdi, boiled potatoes, roti with vegetables — and draws a firm line against anything oily, heavily spiced, or unfamiliar. Three to four hours before the race, runners should eat a light, carb-forward meal: oatmeal with honey, idli with minimal chutney, or poha. In the final hour, a banana, a few dates, or a pre-tested energy gel can offer a last, gentle boost.
Recovery nutrition is equally critical. Within thirty to sixty minutes of finishing, the muscles are at their most receptive, and Sheikh recommends quick options like chocolate milk, a banana with whey protein, or coconut water with nuts. A fuller meal — rice and dal, eggs or paneer, grilled protein with roti — should follow within two hours.
The foods to avoid are as telling as those to embrace: raw salads, fried dishes, alcohol, excess caffeine, and above all, overeating. Sheikh's advice carries an almost austere clarity — trust the familiar, honour what your body has practised with, and let disciplined simplicity carry you across the finish line.
Nearly 69,000 runners are preparing to flood Mumbai's streets on January 18 for the Tata Mumbai Marathon, one of India's largest running events. For most of them, the weeks of training will come down to what happens in the hours before and after they cross the finish line—and much of that depends on what they put in their bodies.
Sameera Sheikh, a microbiologist and sports nutritionist with eleven years of experience, has spent her career watching runners sabotage their own efforts with poor food choices on race day. The principle is straightforward: your muscles need stored carbohydrates to sustain hours of running. But getting there requires discipline and, counterintuitively, a willingness to eat boring food.
In the days leading up to the marathon, Sheikh recommends leaning into carbohydrate loading with foods that won't surprise your digestive system. Brown rice, khichdi, boiled or roasted potatoes, roti with vegetables, and curd if your stomach tolerates dairy—these are the anchors. The rule is absolute: race week is not the time to experiment. Anything oily, aggressively spiced, or unfamiliar should be off the table entirely.
Three to four hours before the race begins, runners should eat a meal that is high in carbohydrates but low in fat and fiber. A banana with peanut butter on toast works. So does oatmeal cooked in water with honey, idli with minimal chutney, or a light preparation of poha or upma. The logic is simple: these foods deliver steady energy without overwhelming the gut. In the final hour before the start, if hunger strikes, a single banana, a handful of dates or raisins, or an energy gel—but only if you've tested it during training—can provide a last boost.
What happens after the race matters just as much. The window between finishing and the next two hours is when muscles are most receptive to absorbing nutrients. Within thirty to sixty minutes of crossing the finish line, Sheikh recommends a quick recovery option: a banana with whey protein, chocolate milk, a smoothie made with banana and berries, or coconut water with nuts. Within two hours, a full meal should follow—rice and dal with vegetables, eggs or paneer with carbohydrates, grilled chicken or fish with rice or roti, or curd to support gut health.
What to avoid is equally important. New foods or drinks have no place on race day. Raw salads and other high-fiber foods risk digestive distress. Fried meals and cheese-heavy dishes sit too heavily in the stomach. Alcohol and excess caffeine both promote dehydration, the last thing a runner needs. Overeating before the race is perhaps the most common mistake: runners often eat too much in an attempt to fuel up, when what they actually need is modest, familiar portions.
The through-line of Sheikh's advice is almost austere in its simplicity: stick to what you know, eat what your body has practiced with, and trust that boring food will carry you farther than anything adventurous. For runners stepping up to one of India's biggest marathons, that discipline might be the difference between finishing strong and hitting the wall.

Your muscles need enough stored carbohydrates to sustain you through hours of running— Sameera Sheikh, sports nutritionist
This is the recovery window when muscles absorb nutrients best— Sameera Sheikh, on the 30-60 minute post-race period
The Hearth Conversation Another angle on the story
Why does it matter so much what you eat before a marathon? Isn't training the real work?
Training builds the engine, but fuel is what keeps it running. Your muscles store carbohydrates as glycogen—that's your currency for hours of running. Without enough of it, you hit a wall. But it's not just about quantity; it's about timing and digestibility.
So why do so many runners get this wrong?
Nerves, mostly. People get excited or anxious and either skip meals or try something new to calm themselves. Race week is when people experiment, which is exactly when they shouldn't. Your gut has no surprises to spare.
What's the biggest mistake you see?
Overeating before the race. Runners think more food equals more energy, but a heavy stomach during running is a disaster. You want enough to sustain you, not so much that your body is still digesting while you're running.
And after? Why is that recovery window so critical?
Your muscles are primed to absorb nutrients right after you finish. It's like a door that opens for a couple of hours and then closes. If you miss that window, recovery takes longer and you feel worse the next day.
So chocolate milk actually works?
It does. It has carbs, protein, and fluid—everything you need in that first hour. It's not fancy, but it's effective. That's the whole philosophy: simple, familiar, proven.
