For example, a 68 kilo runner should consume grams—or 2, calories—of carbs per day. During his research, Rapoport developed an even more precise formula that factors in variables including age, resting heart rate, VO2 max, and predicted finishing time.
The extra kilos mean you get a gold star for carbo-loading properly. That means your body will be hydrated and fueled as you start the race, ensuring you cross the finish feeling strong. According to Natalie Rizzo, M. Mid-afternoon snack: Medium sweet potato microwaved , topped with cinnamon; 30 g of dark chocolate; and pair with g of coconut water 80 grams. Carb Total: grams. Pack plenty of snacks, such as energy bars, pretzels, and crackers, and check menus online and make restaurant reservations.
You should also eat after taper runs. Eat on the early side so you have lots of time to digest. Race Morning: Have Breakfast Three hours before the start, eat grams of carbs, like a bagel and yogurt or sports drink and oatmeal, says Ryan.
Early race? One of the best ways to do that is by consuming a sports drink , an energy gel , or an energy chew. Products that contain two kinds of sugars, such as glucose and fructose, are absorbed even quicker. Take a drink, gel, or chew every 30 to 45 minutes for runs lasting 60 minutes or longer to top off your glycogen stores. Aim for to calories, or 30 to 60 grams of carbs. Many of these options also include electrolytes—which aid in maintaining a proper fluid balance—and caffeine, which can help you power through the last few miles.
It contains more carbs than most sport drinks, has no artificial flavours or preservatives, and forms a hydrogel when it reaches the stomach, helping to guard against GI issues.

Even though you work your entire body when running including your arms, hips, and core , your feet bear a lot of the burden.
Runners are no strangers to stress. Physiologists began testing runners to see what was happening when they were successful and when they were not. Coaches who always seem to figure out what works before physiologists do had already seen that using long distance runs could help runners avoid the wall and that increasing carbohydrates in the diet was helpful as well. There is even a story of Arthur Lydiard telling his Olympic runners to add another spoonful or two of honey to their morning coffee before heading out for their mile long runs because they would perform better.
And of course, Lydiard championed the idea that doing regular long runs could help runners of all distances delay fatigue. Taking it a step further, researchers wanted to see if they could really maximize muscle glycogen stores right before a long race by first depleting them and then refilling them. It was known that when muscle glycogen stores are low, there is a really strong stimulus in the body to refill them.
From this research, the first carbo-loading regimen — deplete, deprive, replenish — was created. It is a logical and simple strategy, but does have some serious drawbacks. In this strategy, you begin seven days before your race. You first do a big workout to fully deplete your glycogen stores. This is usually a speed workout with lots of repetitions to burn through your carbohydrate stores.
But it could be any running that depletes your glycogen stores. Then, and this was the critical step in this method, you avoided carbohydrates over the next three days. You purposely ate a low carbohydrate diet so as not to refill your glycogen stores. Then, three days before your race, you began to eat lots of carbohydrates.
Sure enough, it worked! Research showed that if you followed this regimen, you would indeed have really full glycogen stores. However, this big glycogen tank came at a cost. First, you had to do a really hard workout just seven days before your big race.
This introduced a risk of injury, peaking too soon and was generally worrying for the athlete. Second, by depriving the runner of carbohydrates for the three days after the glycogen-depleting workout, she would feel very, very bad in the next few runs. No energy. Very tired and often quite grumpy. The legs were dead and heavy and the runner often felt very, very unfit. As you might imagine, this is not the ideal mental state for someone with a big race coming up.
Lucozade Sport is aiming to get one million people moving more by with the Made To Move Campaign. Sign up for our daily newsletter Newsletter. Nick Harris-Fry 17 Apr Except there are always rules. Five rules, to be exact. Save carb-loading for activities that are going to last 90 minutes and over. You should build up your carb intake over two to three days before the race. It may — probably will — lead to stomach issues.
Too much food will leave you feeling sluggish. A 70kg person should aim for around 2, calories of carbs in each of the final two days before an event.
