Operating a profitable marathon is undoubtedly difficult. At 26.2 miles, there’s extra alternative for issues to undermine the end result of the race. And one space that units the marathon other than shorter races is fueling. The human physique solely shops sufficient carbohydrate within the muscle tissues, blood, and liver (within the type of glycogen) for roughly 20 miles of operating, particularly at extra strenuous intensities.
Run out of gas and the inevitable crash or bonk occurs. Any marathoner who has “hit the wall” round mile 20 of a marathon will attest to the pervasive fatigue and dead-leggedness that follows. Slowing down is physiologically essential to preserve the quickly diminishing gas shops that energy a marathon efficiency.
The answer? First, correct marathon coaching is important to show your physique to preserve gas and use it properly. Subsequent, a mixture of carb-loading earlier than and throughout the race will enhance carbohydrate shops and obtainable gas that will help you end the marathon robust.
Observe these do’s and don’ts of marathon fueling to assist your subsequent marathon be your greatest.
Do Carb-Load Earlier than the Race
Carb-loading works. In a examine printed within the Worldwide Journal of Sports activities Medication, researchers adopted over 250 runners who competed on the London Marathon. They discovered that solely 12 % consumed sufficient carbohydrates earlier than the race—and those who did ran a mean of 13.Four % quicker!
The brand new tips counsel 7 to 10 grams of carbohydrates for each kilogram (2.2 kilos) of physique weight. That is admittedly extra carbohydrates than most runners are used to consuming; 1 to 2 liters of sports activities drink is a useful method to make consuming all these carbs doable.
Take your pre-race fueling critically. For a 4-hour marathoner, this might imply operating greater than 25 minutes quicker than in case you didn’t give attention to carb-loading!
Don’t wing it
A runner as soon as informed me he was going to depend on adrenaline to get him over the end line of his first marathon. However that’s a really dangerous concept!
First, adrenaline just isn’t sufficient gas for an endurance occasion (it’s for brief bursts of excessive depth power, usually in a “battle or flight” scenario).
Not having a diet plan for race day is like going into an examination with out learning. You merely won’t be ready.
As a substitute, use the guidelines on this article to place a plan collectively. And naturally, observe it earlier than the race.
Don’t do something new on race day
This can be a well-worn piece of recommendation for any runner, irrespective of the space. Don’t put on new sneakers, shorts, or have completely different meals for breakfast. And experimenting with new fuels or a special fueling schedule is introducing a probably unpleasant GI scenario!
Follow meals which might be suitable along with your abdomen each the day earlier than and on race day.
Which leads us to my subsequent level…
Do observe earlier than race day
Identical to you observe lengthy runs, pacing, and racing technique earlier than your purpose marathon, you must also observe your actual fueling technique earlier than the large day. There ought to by no means be any surprises once you’re racing.
Purpose to run two to a few lengthy runs utilizing the identical fueling schedule you intend to make use of on race day. Make sure that every thing is deliberate: use the identical gas, on the identical time of day, in the identical timing sample that you’ll on the day you race your marathon.
This helps make sure that there received’t be any surprises once you lastly line as much as race.
Do devour sufficient carbs throughout the marathon
In the course of the race (and once you’re practising), it’s important to eat the correct quantity of carbohydrates.
Too little and also you danger limiting your potential. An excessive amount of, and also you danger GI misery.
With correct carb-loading earlier than the race, most runners then want about 45 to 60 grams of carbohydrate per hour throughout a marathon for optimum efficiency. This works out to be about two gels (or equal) per hour.
To produce a gradual stream of gas and to cut back the probability of a porta-potty break, break that into two classes: one gel each 30 minutes throughout a marathon.
Additionally be sure you drink roughly Four ounces of water with every gel. The electrolytes within the gels should be processed with water (and too many electrolytes, in case you drink sports activities drink, can leech water out of your cells for that processing, inflicting dehydration). One or two mouthfuls of water is all you want.
With these methods, fueling for a marathon turns into less complicated. And racing the marathon can be much more profitable!
