Hydration for endurance events -

There's a lot of debate around the optimal dosage of carbohydrates because it can be so individualised, but there are credible guidelines on how much carb athletes need per hour. The recommended amounts increase in line with the duration of activity, in recognition of the fact that stored 'endogenous' fuel is sufficient for shorter bouts of activity, but these stores become depleted over time.

So, we need to get more energy on board to avoid depletion and maintain performance levels for longer activities. Not sure how much carb you need? Take the Quick Carb Calculator to get some fueling guidelines for your next event.

When individualising levels of carbohydrate intake for your own circumstances, the following rules of thumb are useful:. In what exact format i. gels, energy bars, carb drinks, chews you get these carbs into your system is an area of furious debate, but I think it's a distraction from the fundamental issue of getting the correct amount of carbs dialled in as the first priority.

In my experience, plain energy chews , gels or bars with clearly marked carbohydrate contents on the packaging are the best way to go as they are often easily digestible. The best way to go about the trial and error process is to perform simulation training sessions where you perform the activity you're fuelling for as close to race intensity for a prolonged period of time ideally close to race duration too.

This approach will allow you to build up an initial picture of what different levels of carbohydrate intake are doing to your ability to perform and to your stomach.

Whilst there are some inter-individual differences in the amount of carbs that are needed to sustain performance, there seems to be relatively less intra-individual variance.

Optimal carb intake is reasonably stable once you dial it in, but fluid loss via sweating is significantly more volatile, both between and within individuals. So, hydration requirements can be lot more variable too in no small part due to the huge role that environmental conditions and clothing can have on sweat rates.

One sensible way to approach this issue is to start at the edges and to work inwards by beginning with the lowest amount of fluid intake needed For activities of less than ~60 minutes and even up to 90 minutes in some cases , fluid intake of close to zero is definitely an option if an athlete starts well hydrated and has plenty of access to drinks to top up again afterwards.

This is certainly true in colder conditions when sweat rates are blunted because core body temperature is much easier to manage.

When you get into the zone of hours and in hotter and more humid conditions , fluid intake definitely starts to be required to maintain optimal output when you're going as hard as possible. Without it, sweat losses can result in a decrease in blood volume that manifests in cardiovascular strain and a reduction in performance.

It's true that a more structured approach to drinking might be beneficial for this kind of duration in certain situations e. In these cases, some experimentation starting around ~ml ~16oz per hour and adjusting up or downwards from there as necessary is sensible.

For much longer sessions and races i. Whilst that sounds like and is! a very wide range, it's fair to say that for a large majority of athletes something in the range of mlml ~oz per hour is a decent zone in which to start some experimentation.

And be more aggressive if you have a big sweat rate see this article for details on how to measure your sweat rate or if the conditions are very hot or humid.

Be very mindful that hyponatremia is a real risk if you significantly overdrink. This article is a useful resource to look at to understand the topic in more detail.

This inevitably leads to the best outcomes when you become skilled at it and there's no real substitute for building up a large database of experience to get to this point.

This article describes in detail how pro IRONMAN athlete Allan Hovda has been measuring his own data and is starting to reap the benefits. For shorter activities under about minutes in duration , it's highly unlikely that even the heaviest, saltiest sweaters need to worry about sodium replacement too much in the context of a single session anyway.

When you get to durations of hours at a high intensity and in conditions that drive high sweat rates, sodium replacement can start to be important, especially for those with heavy losses.

So, this is the kind of range to start experimenting in. When stepping up to the really long stuff hours plus the differences in sodium loss really starts to tell and there's potentially quite a large divergence between people who still require very little exogenous sodium input to those whose intake levels need to be very high indeed.

That's based on me having both a high sweat rate 1. Image Credit: dryrobe ©. Your body is roughly 65 percent water and this is held in two main compartments. Nearly two-thirds of it is found inside your cells intracellular fluid and the remaining third is outside the cells extracellular and interstitial fluid.

Of the extracellular fluid, roughly 20 percent around 5 liters in an average adult is in your blood. However, since you are a living, breathing, peeing, sweating, drinking, metabolically active human being your exact hydration status is in constant flux. Your body does an amazing job of maintaining optimal fluid balance by shifting fluid around internally, peeing out any excess, and making you thirsty so you drink when you need to take more in.

This all works incredibly well in the context of the normal range of inputs and outputs. Whilst it is probably sensible to take in an extra cup of fluid here and there in the final days to make up for any slight level of lingering dehydration, overall there is no great benefit to drinking way more than you normally would.

Most of the issues over-drinking creates are related to the fact that body fluids are not just water but are in fact, a very salty mixture containing electrolytes. Electrolytes are crucial for performing a host of bodily functions including cellular communication, nerve impulse transmission and muscle contraction so their relative concentrations have to be regulated very tightly to allow them to do their jobs properly.

Essentially, what happens if you drink too much is that you begin to dilute this critical level of sodium in the blood, potentially arriving at the start line depleted of electrolytes. In extreme cases, this can lead to a dangerous condition called hyponatremia. Hyponatremia is dangerous because as more fluid enters the bloodstream the body has to move some of it back out again to balance the sodium content.

This causes swelling of the cells which, if it occurs in the brain, leads to headaches, confusion, and even coma or death. Due to the fact that a few people are indeed dying from this every year in sport, it is a hot topic in sports medicine at the moment and provides a very compelling reason for not drinking to excess during training and races.

It is widely suggested that drinking to thirst i. listening to your body and only taking in as much as your sense of thirst tells you that you need is the best way of preventing hyponatremia, and this seems to be good advice to follow in most normal circumstances. Whilst hyponatremia may well be less likely to occur in the immediate build-up to an event as your body is more able to pee out any excess water you take in, this still does not mean that drinking very large volumes of fluid is either necessary or safe, especially at times when sweat losses are not great as is often the case when you are tapering down.

This is because as you drink more and pee more, additional sodium is lost in urine and the overall levels of sodium in the blood gradually get diluted down to their lowest acceptable levels.

Whilst this might not manifest itself as a serious case of hyponatremia, even a mild case can adversely affect your performance as low blood sodium levels make you feel fatigued and lethargic. In essence, a good pre-competition hydration routine should deliver you to the starting of your race optimally hydrated i.

For individuals who are heavy sweaters, more fluid and electrolytes especially sodium will be necessary to support endurance performance and overall health compared to individuals who are less prone to sweating.

Details on how fod calculate fluid loss Antioxidants and immune system support adjust accordingly are provided later Hydraation this article.

Hydratio also Hysration fluid and electrolyte balance. In general, running in hot climates, regardless of whether they are dry or humid, will increase fluid and electrolyte needs.

This is because runners lose additional fluids and electrolytes through increases in sweating caused by hot environments. Thus, drinking more fluid assists with better temperature regulation and endurance performance in hot climates.

Surprisingly, fluid and electrolyte needs are also increased when running in cold, dry climates. This is because breathing increases, allowing additional fluids to be lost through respiration.

These are important considerations to remember when making a hydration plan. Altitude is another factor to consider when striving to remain well-hydrated.

Research has shown that runners become dehydrated more quickly when running at higher altitudes. This is because the rate of breathing increases due to less oxygen availability at higher elevations.

Remember to keep the altitudes of your training and competition environments in mind when assessing your fluid and electrolyte needs. In general, new runners that are not used to intense exercise often experience lower rates of sweating, but higher rates of breathing during exercise than trained runners.

Because these factors affect fluid and electrolyte balance in opposite directions, it is essential that runners calculate fluid losses after exercise to determine their exact needs. Fluid-electrolyte imbalances can be associated with a variety of health conditions, but the two main issues facing runners are dehydration and overhydration.

Dehydration is a condition of losing more fluid than is taken in. It is common among endurance runners due to frequent, vigorous, and long bouts of exercise. In the early stages of dehydration, there are no major health risks.

Mild dehydration can be identified by being able to recognize these common symptoms:. If dehydration progresses to moderate and severe stages, symptoms often escalate to nausea, confusion, and even lethargy. At the point of severe dehydration, organ damage or even death could occur.

It is vital that runners stay ahead of dehydration — not only to achieve optimal performance, but to prevent the development of serious health risks. Overhydration, known as hyponatremia, is often caused by drinking too much water.

The resulting fluid-electrolyte imbalance can cause headaches, confusion, nausea, and fatigue in mild cases or quickly progress to seizures, coma, or even death in severe cases. Because endurance runners have higher fluid needs than the average person, this group is also at higher risk of experiencing hyponatremia through well-intentioned efforts to remain hydrated.

With this in mind, it is imperative that runners balance their water intake with sources of electrolytes as well. Keep reading to find out how this can be accomplished. Determining fluid and electrolyte needs as an endurance runner can be challenging because there are a variety of conflicting recommendations.

With this in mind, Tables 1, 2, and 3 provide the current evidence-based fluid and electrolyte recommendations for before, during, and after endurance exercise. It is recommended that you use these guidelines as a starting point to create a personalized hydration plan.

This will ultimately result in a hydration regimen that allows you to feel and perform your best. Two to four hours before exercise, runners should drink 0. You should be comfortably full when you begin exercise.

If you tend to be a heavy sweater or are exercising in a hot climate, your needs may be closer to 0. However, if you are going for a shorter run or do not sweat as much, you can drink closer to 0. You can always adjust the amount you drink before your next run if you find that you need more or less.

If you are doing a morning run and do not have time to hydrate 2 to 4 hours before exercise, drink at least 6 to 8 oz of water when you wake up. It is also important that you remain well-hydrated the day before your morning run. Example: A lb individual should drink between Most pre-exercise hydration should come directly from water.

If you would like to consume a sports drink with carbohydrates and electrolytes, do so within an hour of exercise. If you are exercising for more than an hour, supplement with electrolytes.

Products with both electrolytes and carbohydrates will be most advantageous to performance. You can choose a sports drink, electrolyte powder, gels, or gummies.

Salty foods such as pretzels and crackers can be a good option too. If you are a heavy sweater or are exercising in a hot climate, make sure your electrolyte source is rich in sodium.

Individuals in this category should consume roughly milligrams of sodium per hour during prolonged exercise. To assess fluid loss, weigh yourself before and after exercise. Any change in weight is reflective of a change in fluid status. For every lb of weight lost, rehydrate with 16 to 24 oz of fluid.

If you have gained weight, this is an indicator that you are overhydrating during exercise. Electrolyte replacement after exercise is dependent upon the amount of fluid lost during exercise.

If you find that you have to replace a lot of fluid to maintain your pre-exercise weight, add an electrolyte beverage in alongside your water to avoid hyponatremia.

Your post-exercise meal can also contribute towards meeting your electrolyte needs. Because sodium is the main electrolyte lost through sweating, prioritize salty foods after exercise.

These recommendations apply to all running durations — whether you are completing a short or long run. However, if you are planning to run a shorter distance 3 miles or less and do not want to carry fluids during your run, just make sure that you hydrate before your run and replenish your fluid and electrolyte stores after your run by following the guidelines provided in Tables 1 and 3.

While the formal fluid and electrolyte guidelines provide runners with valuable technical information, it can still be difficult to implement and personalize these concepts in practice.

How to hydrate for endurance sports (the right way)

There is, I believe, a huge difference. The environment that we now enjoy in much of the developed world—specifically in terms of our free and ready access to water and salt—is also very different from that of our ancestors. And even if you are perfectly aware of your thirst signals as a general rule, the elite athletes we work with are very in touch with their bodies , the demanding and complex nature of competition can make it difficult to find physically and tactically ideal moments to hydrate.

Drinking water to thirst is very likely sufficient for short and light activities where sweat losses are low to moderate, but the data is a lot less clear for longer and hotter events , where sweat loss can be considerable over many hours.

It was even copied by many of his competitors, presumably because it worked. More recent research showed that triathletes who were given salt tablets vs.

a placebo during a middle distance race were ~26 min faster on average. The study also showed that the group taking salts rehydrated more effectively than the control group. This certainly tallies with my own experiences using sodium supplements during long, hot races.

Sports drinks are arguably overused by a lot of people, but they have been proven time and time again to provide performance-enhancing benefits to athletes and humans in general in the right scenarios. There are lots of scenarios where just drinking water to thirst is sensible, like for basic day-to-day hydration.

Drinking during competition is desirable compared with fluid ingestion after or before training or competition only. Athletes seldom replace fluids fully due to sweat loss. Proper hydration during training or competition will enhance performance, avoid ensuing thermal stress, maintain plasma volume, delay fatigue, and prevent injuries associated with dehydration and sweat loss.

To reinforce that last point, in one study , researchers found that when cyclists were hypohydrated, performance declined in lock step with rising skin temperature. Should you just drink more water, then? Since sodium regulates fluid balance, adequate sodium intake is required to retain water and maintain the electrochemical gradient produced by higher concentrations of sodium outside cells and higher concentrations of potassium inside cells.

A consensus statement from the International Olympic Committee reads:. To prevent dehydration, many athletes guzzle sodium-free water beyond what thirst prompts.

To make matters worse, guzzling water creates a bigger problem: Hyperhydration. Hyperhydration, also known as overwatering or water intoxication, is a potentially fatal state of electrolyte disturbance brought on by excessive water consumption.

You see this a lot in marathons. Runners drink electrolyte-free water on a set schedule, dilute blood sodium levels, then suffer the consequences of exercise-associated hyponatremia low serum sodium. Hyponatremia is serious stuff. In the beginning, it causes headaches, cramps, confusion, and fatigue.

As sodium levels continue to fall, seizures, brain damage, and even death can result. More than a few elite athletes have perished from hyponatremia. What about dehydration? Not one sports-related death, in all the medical literature.

Fortunately, exercise-associated hyponatremia is fairly easy to prevent and reverse. Sodium is an electrolyte that helps you transmit nerve impulses, regulate blood pressure, and maintain body water. And when sodium levels fall to hyponatremic levels, the consequences are no joke.

Sodium needs go up in proportion to sweat loss. And the volume of sweat loss depends on the activity, ambient temperature, humidity, and a few other factors. According to a paper from the Journal of Sports Sciences, vigorous exercise in warm climates can provoke sodium losses of 3.

Simple: Drink salty water. A published example will help make my point. In one randomized controlled trial , researchers rounded up 26 hyponatremic runners after a km race, and gave them one of two interventions: IV sodium or a salty solution to drink.

Both interventions restored their sodium levels. The takeaway? Consuming sodium before and during exercise can help maintain euhydration, and prevent problems from developing later on.

Different activities require different hydration strategies. A 2-hour soccer match in 95 degrees and high humidity levels, however, will require frequent sodium and fluid replenishment.

If you remember anything from this article, remember these:. Thirst is a tightly regulated system. And when you do drink , remember to…. You lose both sodium and water through sweat.

If you only replace the water, your sodium levels will fall.

Because most endurance training programs include a great deal of training off the track, safety when running near traffic and other hazards is an important consideration.

Overtraining and heat-related problems are significant issues in these events; avoiding these situations is an important part of safety and injury prevention. Hydration, environmental conditions, and nutrition are also more significant in the endurance events because of their longer duration.

Dehydration thickens the blood and makes it harder to pump think water versus molasses. On average, males can lose 2. In warm weather athletes should restrict their fluid loss to 1 to 2 percent of their total body weight. Each pound about 0. Runners should consume 16 to 24 ounces to ml of fluid containing electrolytes per pound about 0.

These figures are estimates; there is great variability among individuals and environmental conditions. In addition, for optimal performance for events lasting longer than one hour, athletes should consume to calories per hour during the event either as fluids or in addition to fluids.

Performance in endurance events can be significantly affected by extremes in climate. In regard to heat, the longer the event, the greater the impact. In the case of the marathon, for every 5 degrees the temperature rises above 50 degrees Fahrenheit or about 3 degrees it rises above 10 °C , the athlete's final time typically increases by about 0.

If the temperature is above The body sheds heat through the evaporation of sweat. When humidity is high, evaporative cooling is inhibited, and so is the body's ability to shed heat. Considering all this, an athlete that is in that sweet spot of happy hydration is an athlete that can perform their best.

Enter pre-hydration. Pre-hydration is a strategic way to start well-hydrated before your event. You are adequately hydrated, but with an edge. Now take this number and multiply by 5 and then again by This is the range in milliliters you need to drink over the next hours.

So…for about hours before your event, sip on ounces of fluid to be pre-hydrated. You can also do this for the day before a big race. Drink about 8 oz every hour. No need to drink so much that you are urinating super often or your pee is really clear.

Just drink enough to feel hydrated and refreshed and ready to go hard! If you have other questions like:. All this and more is covered in our Perfect Hydration for Athletes course!

Of course, the wider topic of good nutritional practices for athletes is significantly more complex than the turnover of these 3 elements. But for me, the trio sit head and shoulders above the others in the hierarchy of importance during endurance exercise. You can further refine these levels on the basis of your own deeper knowledge of your personal requirements.

And then and this is the most important step , apply some structured trial and error to test out your estimates in the real world, and settle on amounts that work for you. Before getting into the specifics of each lever, it's worth emphasising that the advice is based on optimising performance when going extremely hard in training or racing.

It doesn't necessarily apply in its entirety when undertaking easier training because requirements in all 3 areas will be reduced when rates of output are lower.

Ingestion of carbohydrate has long been known to improve endurance performance, primarily during events lasting longer than 45 minutes it's worth reading this paper by Asker Jeukendrup for an in-depth review of carbs and performance.

There's a lot of debate around the optimal dosage of carbohydrates because it can be so individualised, but there are credible guidelines on how much carb athletes need per hour.

It gets confusing because going too hard especially in the heat can lead to dramatically reduced blood flow to the gut this is reduced significantly during exercise of any level, but especially if you push too hard and can mean that you're unable to absorb calories and fluids at rates that you could normally tolerate.

Endurance athletes should drink beverages containing carbohydrate and electrolyte during and after training or competition. Drinking during competition is desirable compared with fluid ingestion after or before training or competition only.

Athletes seldom replace fluids fully due to sweat loss. Proper hydration during training or competition will enhance performance, avoid ensuing thermal stress, maintain plasma volume, delay fatigue, and prevent injuries associated with dehydration and sweat loss.

It is recommended that athletes drink about mL of fluid solution 1 to 2 h before an event and continue to consume cool or cold drinks in regular intervals to replace fluid loss due to sweat.
