Here’s how to hydrate for better performance.Here’s how to hydrate for better performance.Staying hydrated seems simple enough—drink water when you’re thirsty and stop when you feel like you’re done, right? Well, it’s a bit more complicated than that, especially for runners. 

That’s because not understanding the complicated equation of race distance and intensity combined with water and electrolyte intake can ruin a long run or race, not to mention have serious health repercussions. Drink too little and your ability to power through your workout suffers; drink too much and you can get sidelined by nausea and frequent pee breaks. 

And even though you might first worry about dehydration for those summer runs, researchers found that the newer you are to running and the slower you run, the more likely it is that you will drink too much water while racing. (We’ll talk more about this later.)

To that end, much of the research demonstrates that mastering the art of hydration when you run isn’t as simple as it seems. Keep reading to find out if you drink water the wrong way—and how to drink water right.

6 Ways You Drink Water Wrong and 6 Ways to Drink Water Right

❌ Wrong Way: Gulping water during a race

✅ Right Way: Sip as you run

It’s okay to slow a little to make sure you’re getting in your fluids during a race, but gulping water at each aid station can ultimately slow you down and also lead to an upset stomach.

That’s because drinking too much water too quickly overloads the stomach, causing it to rapidly stretch. This can lead to discomfort and potential nausea, Justin Mullner, M.D., a board-certified primary care sports physician with the Orlando Health Jewett Orthopedic Institute in Florida tells Runner’s World.

Take small sips of water (or electrolyte drink) every 15 to 20 minutes, depending on the temperature and intensity of the run.

Combining a run with too much water is even more likely to cause nausea. That’s because intense exercise directs blood flow away from the stomach and toward the muscles, causing digestion to slow down. “So you put a bunch of water in there and the stomach really can’t handle it effectively and efficiently,” Mullner says.

A better strategy is to take small sips of water (or electrolyte drink) every 15 to 20 minutes, depending on the temperature and intensity of the run. “This approach helps maintain a steady level of hydration and prevents the stomach from becoming overly full,” Meghan Kennihan, a RRCA- and USATF-certified running coach, tells Runner’s World.

❌ Wrong Way: Drinking from a dirty water bottle✅ Right Way: Regularly clean your bottle

Your trusty water bottle is always there when you need it. Sadly, constant use means you’re probably getting more than water. Unless you regularly clean your water bottle—which means daily according to Mullner—you could be getting a dose of bacteria or even mold.

Every time you put your mouth to the water bottle and use your hands to open and close it, you transfer bacteria that can make its way inside. The moist environment inside your water bottle provides an optimal breeding ground for bacteria and mold, especially if you live in hot, humid areas. If left unchecked, the bacteria and mold can continue growing, potentially causing you to experience symptoms similar to food poisoning (such as stomach pain or cramps, diarrhea, and vomiting), per the Centers for Disease Control and Prevention. People with mold sensitivities can have a flare-up of allergy symptoms.Ideally, you’d wash out your reusable bottle—whether plastic, stainless steel, or glass—with soap and warm water each time, Mullner says. “It’s even more important if you’re using the bottle every single day or drinking beverages other than water,” he says. Mixing electrolyte powders or adding a sports drink to your bottle, for example, means more material for bacteria.Signs your bottle could use a good scrubbing include visible residue, a funny or foul odor, or changes in how things taste, Mullner says.

❌ Wrong Way: Waiting too long to hydrate before a run or race✅ Right Way: Start early

When preparing for a long run or race, many runners forget to hydrate until they’re practically toeing the starting line, “which is a bad idea because it doesn’t give the body enough time to absorb and utilize the fluids,” Kennihan says.

Staying well-hydrated in the days leading up to your long run or race can help you perform well, avoid feeling overly full, and reduce restroom stops. Be especially diligent about drinking water starting the day before a long run or race, and check your urine color to be sure you’re getting enough. “Really dark yellow is a sign that you’re not well-hydrated,” Mullner says. “Ideally, it has a slight tinge of yellow.”

Drink 16 to 20 ounces of water about 2 to 3 hours beforehand and then another 8 to 10 ounces 20 to 30 minutes before running.

Individual fluid needs vary. However, a general guideline for the day of the event is to drink 16 to 20 ounces of water about 2 to 3 hours beforehand and then another 8 to 10 ounces 20 to 30 minutes before running, Kennihan says. You may need to adjust your intake according to your body size, run distance, and outside temperature.

❌ Wrong Way: Drinking too much water on long runs✅ Right Way: Balance electrolyte intake with water

It’s critical to drink enough water during long training runs and races. However, drinking lots of water, and only water, can lead to overhydration, meaning you have too much water in your body.

Hyponatremia is an extreme version of overhydration, and occurs when sodium levels in the blood are lower than recommended, leading to muscle cramps, headaches, nausea and vomiting, low energy, and confusion, per the Cleveland Clinic. Normally, your body keeps your electrolytes in balance by taking the minerals from the foods you eat and filtering the excess through your urine. However, intense exercise causes electrolytes (particularly sodium) to be quickly lost through sweat, and hot, humid temperatures only accelerate this loss, per the American College of Sports Medicine. 

It's not just new runners who tend to overhydrate. At the other end of the spectrum, 41 out of 63 finishers at an ultramarathon also finished with mild or severe hyponatremia, according to a 2019 Frontiers in Nutrition study.

Take in electrolytes in addition to water if you’re running for longer than 60 minutes or in hot, humid temperatures. Drinking water without replacing electrolytes dilutes the remaining electrolytes (again, sodium in particular) in your blood. “You can potentially get yourself into trouble with hyponatremia,” Mullner says.

To prevent an electrolyte imbalance, take in electrolytes in addition to water if you’re running for longer than 60 minutes or in hot, humid temperatures. Bring an electrolyte drink, some gels, or another electrolyte supplement.

❌ Wrong Way: Drinking a pure sports drink✅ Right Way: Water it down

Sports drinks offer a convenient delivery system for carbs and electrolytes while running. Still, many runners prefer to water things down.

“Many sports drinks are too concentrated, leading to stomach cramps and nausea. Diluting them can still provide the necessary electrolytes and carbohydrates without overwhelming the stomach,” Kennihan notes.

The optimal ratio of sports drink to water depends on your preferences and the makeup of your drink. Mullner suggests diluting your sports drink to the point where it’s most palatable for you.

Diluting sports drinks can still provide the necessary electrolytes and carbohydrates without overwhelming the stomach.

The exception: Don’t dilute a sports drink that contains carbohydrates if you’re using it for energy purposes. “Some sports drinks have carbs in there to help extend the amount of time you can perform, and if you’re trying to absorb carbs better, you would have it with some electrolytes,” Mullner says. Adding water can cut down on how many carbs you get per sip, limiting performance benefits.❌ Wrong Way: You don‘t know about your med’s side effects

✅ Right Way: You read labels and talk to your pharmacist

Some over-the-counter and prescription medications can affect an athlete’s hydration, says Kennihan. NSAIDs, such as ibuprofen and aspirin, can reduce blood flow to the kidneys, which can impair their ability to conserve water and electrolytes, potentially leading to dehydration, especially during prolonged physical activity like running. 

Similarly, diuretics, which are prescribed for conditions such as hypertension and edema, increase urine production and promote the excretion of water and electrolytes from the body. Increased urine output can lead to a significant loss of fluids and electrolytes, making it easier for runners to become dehydrated, particularly in hot and humid conditions or during long-distance runs. 

Likewise, antihistamines can reduce saliva production and increase the risk of dry mouth and dehydration, while laxatives can cause increased bowel movements and fluid loss.Lastly, stimulant medications, such as those used for attention deficit hyperactivity disorder (ADHD), can increase sweating and fluid loss, potentially leading to dehydration if fluid intake is not adequately maintained.

Bottom line: As a runner, remember that hydration is as much a part of your performance as actual time on your feet. 

The authors of a 2019 article published in the International Journal of Sport Nutrition and Exercise Metabolism recommended that runners develop a “personalized and practiced race plan” to optimize their fluid and carbohydrate intake based not only on their distance and intensity, but also taking into account their body composition, as well as the weather and other race conditions, such as refueling stations, at each event.

Melissa Jefferson-Wooden delivered a sensational performance in Budapest, storming to victory in the women’s 100m at the inaugural World Athletics Ultimate Championship in a breathtaking 10.62 seconds.

The American produced a superb display of acceleration and composure to claim the World Ultimate Championship title while recording the fastest women’s 100m time in the world this year. Her 10.62 mark underlined her exceptional form and placed her firmly at the top of the global sprinting hierarchy.

Jefferson-Wooden controlled the race through the decisive stages and maintained her form all the way to the finish to secure a statement victory against a field packed with championship pedigree. She crossed the line ahead of Olympic champion Julien Alfred, who clocked 10.74 seconds with a -0.2 m/s wind, while Sha’Carri Richardson took third in 10.76.

Women’s 100m Final

1. Melissa Jefferson-Wooden — 10.62

2. Julien Alfred — 10.74 (-0.2 m/s)

3. Sha’Carri Richardson — 10.76

The victory was especially significant given the quality of the opposition. Jefferson-Wooden held her nerve against Alfred and Richardson, two of the most accomplished sprinters of the current generation, to produce the fastest performance in the world this year when it mattered most.

Alfred once again demonstrated her consistency at the highest level by taking silver, while Richardson completed an all-star podium in a race that brought together three of the biggest names in women’s sprinting.

But beyond the time, the title and the celebration, one of the most touching moments came after the race when Jefferson-Wooden embraced her father, Melvin, in an emotional celebration.

Their moment carried a deeply personal meaning. When Melissa was just 17 years old, she donated her stem cells to help her father undergo a bone marrow transplant after he was diagnosed with myelodysplastic syndrome. Years later, the two shared an unforgettable embrace in Budapest after she had become the World Ultimate Champion.

For Jefferson-Wooden, however, the evening was about far more than a medal. It was the culmination of an extraordinary journey, now highlighted by a world-leading 10.62 seconds on one of the biggest stages in athletics.

With the Ultimate Championship title secured and her father by her side, Jefferson-Wooden leaves Budapest with more than being an ultimate champion. She leaves with momentum, confidence and a powerful statement of intent — turning a high-profile showdown into one of the defining sprint performances of her season.

Audrey Werro has added another major title to her extraordinary season, storming to victory in the women’s 800m at the inaugural World Athletics Ultimate Championships in Budapest.

The Swiss star delivered a commanding performance, taking control from the opening gun and refusing to surrender the lead as she powered through an absorbing battle against two of the biggest names in the event.

Werro stopped the clock at 1:55.88 to become the Ultimate Championships 800m champion, producing another statement performance on one of the sport’s newest and most prestigious stages.

Behind her, Great Britain’s Keely Hodgkinson fought her way to second in 1:56.26, while the Netherlands’ Femke Broeders-Bol completed the podium in 1:56.74.

The result once again brought together the same formidable trio that featured on the podium at the European Championships, but Werro again proved to be the athlete who could rise above the challenge when it mattered most.

Her Budapest triumph is the latest chapter in a season that has already included records, a successful Diamond League Trophy defence and European Championship gold. Now, she can add the Ultimate Championships crown to a growing list of accomplishments.

Werro’s consistency has been particularly impressive in an 800m event packed with elite talent. Rather than simply relying on a fast finish, the Swiss athlete showed her authority by taking the initiative from the beginning and maintaining enough strength and composure to hold off Hodgkinson and Broeders-Bol all the way to the line.

The victory also underlined the remarkable depth of the women’s 800m, with three athletes separated by less than a second at the finish. Hodgkinson’s 1:56.26 and Broeders-Bol’s 1:56.74 showed just how fiercely contested the race was, but Werro’s decision to dictate the pace ultimately gave her the decisive advantage.

For Werro, this was more than another medal. It was another opportunity to demonstrate that her rise is no passing moment. On a stage featuring established champions and elite rivals, she once again produced the performance required to claim the biggest prize.

For Hodgkinson, the silver medal adds another major podium finish, while Broeders-Bol once again demonstrated her ability to compete with the very best over two laps.

But the spotlight in Budapest belonged unmistakably to Werro.

With another championship crown secured, the Swiss star has strengthened her claim as the athlete setting the standard in women’s 800m running. This is Audrey Werro’s era — and the rest of the field is chasing.

Busang Collen Kebinatshipi has delivered another sensational performance, storming to victory in the men’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The reigning world champion stopped the clock at an astonishing 43.39 seconds, smashing his own Botswana national record and moving to fifth on the world all-time list.

Kebinatshipi produced a commanding finish to pull away from his rivals and secure the Ultimate Championship title. American star Rai Benjamin finished second in 44.15, while Jereem Richards of Trinidad and Tobago completed the podium in 44.23.

 Men’s 400m

1. Busang Collen Kebinatshipi — 43.39 NR

2. Rai Benjamin — 44.15

3. Jereem Richards — 44.23

The performance is even more remarkable considering that Kebinatshipi had already rewritten the Botswana record just one week ago in Brussels, where he ran 43.40. In Budapest, he lowered that mark by another 0.01 seconds to establish a new national record of 43.39.

That improvement has also propelled the 22-year-old into rare territory. His latest time now ranks him fifth fastest in history over 400m, placing him among an extraordinary group of athletes who have broken the 43.40 barrier.

Kebinatshipi's victory also caps an extraordinary season for the Botswana star. After establishing himself as a global champion, he has continued to demonstrate that he belongs among the very best one-lap runners in the world.

And there is a major reward for his historic night in Budapest: Kebinatshipi walks away as the Ultimate Champion and $150,000 richer.

From another national record to a place among the five fastest 400m runners ever, Kebinatshipi has turned an already remarkable season into something truly special.

Botswana has its latest sprinting superstar — and Kebinatshipi is showing that his ceiling may be even higher than anyone imagined. 

Marileidy Paulino once again proved why she is the undisputed queen of the one-lap event, powering to victory in the women’s 400m at the inaugural World Athletics Ultimate Championship in Budapest.

The Dominican Republic superstar produced a sensational 49.07 seconds to claim gold, pulling decisively away in the final straight and holding off a fiercely competitive field to extend her remarkable unbeaten run.

Paulino delivered her trademark combination of controlled speed and devastating finishing strength. She remained firmly in contention through the opening stages before unleashing her decisive move down the home straight, where she quickly opened a gap on her closest challengers.

Norway’s Henriette Jæger mounted a strong challenge but could not match Paulino’s finishing speed, crossing the line second in an impressive 49.28. Jamaica’s Nickisha Pryce completed the podium after clocking 49.56, ensuring that three of the world’s leading 400m talents occupied the medals.

The result once again underlined Paulino’s extraordinary consistency at the highest level. She entered Budapest as the world leader after running 48.48 in Paris in June, a performance that also set a Diamond League record. She subsequently remained unbeaten throughout her Diamond League campaign, closing the circuit with a meeting-record 48.64 in Brussels.

Budapest has also become a special venue in Paulino’s career. Three years ago, at the same National Athletics Centre, she captured her first individual world title, marking the beginning of another dominant chapter in her career. She later added Olympic gold in Paris in 2024, further establishing herself among the defining 400m athletes of her generation.

The inaugural World Athletics Ultimate Championship has brought together the sport’s biggest stars in a new winner-takes-the-spotlight format, with Olympic and world champions, Diamond League winners and leading performers competing for ultimate honours.

For Paulino, the occasion once again ended with Ultimate Crown on her arms.

With 49.07 seconds, she did more than win another major 400m title. She delivered another statement of authority, powering through the final straight with the confidence and speed that have made her one of the most dominant figures in modern women’s athletics.

Marileidy Paulino remains unbeaten, remains relentless and, once again, remains the queen of the one lap.

Jakob Ingebrigtsen has made a major decision regarding the remainder of his World Athletics Ultimate Championship campaign, confirming that he will withdraw from the men’s 1500m in Budapest despite producing a sensational performance to win the 5,000m title.

The Norwegian superstar stormed to victory in the inaugural Ultimate Championship 5,000m on Friday night, clocking a season-best 12:59.24 and delivering a devastating finishing kick to defeat Olympic 5,000m champion Cole Hocker and American Parker Wolfe.

Ingebrigtsen’s final 100 metres was arguably the defining moment of the race. The Olympic champion produced a remarkable 12.60-second closing 100m, powering away from the field to secure the $150,000 winner’s prize and underline just how far his fitness has progressed since returning from Achilles surgery.

The victory was particularly significant after what has been an extremely difficult period for the 25-year-old. Earlier in the season, Ingebrigtsen faced serious uncertainty over whether he would even be able to compete at the highest level again. His return has gradually gathered momentum, and his performance in Budapest offered perhaps the clearest indication yet that the Norwegian is rediscovering his formidable racing ability.

But rather than risk pushing his recovering body further, Ingebrigtsen has now opted to step away from the 1500m.

The decision means the highly anticipated showdown with British rival Josh Kerr will not take place in Budapest after all. The two stars had been expected to renew one of the biggest rivalries in modern middle-distance running in the 1500m final.

Instead, Ingebrigtsen is looking beyond the immediate opportunity and towards the bigger picture.

“I’m thinking about 2027… Fitness cannot be faked,” the Norwegian said, signalling that protecting his long-term condition has become more important than chasing another major victory only days after his return to peak-level competition.

The decision comes just one week after an emotionally charged Diamond League Final in Brussels, where Ingebrigtsen finished fourth in the 1500m behind Australia’s Cameron Myers, Kenya’s Phanuel Kipkosgei Koech and American Ethan Strand.

After that race, Ingebrigtsen delivered a fiery assessment of his rivals and questioned the tactics surrounding the pacemaking, particularly involving Hocker. He later acknowledged that there had been “a little too much adrenaline and emotion” when microphones were placed in front of him immediately after the race.

Yet his latest decision shows that beneath the emotion and competitive intensity lies a longer-term strategy.

Ingebrigtsen has already demonstrated that he can compete at an elite level again. His 12:59.24 in Budapest was not simply a victory — it was a statement that the Norwegian remains capable of producing a world-class finish even after months of injury rehabilitation.

Now, however, he is choosing not to gamble with that progress.

For a runner who has spent much of the year fighting his way back from injury, another 1500m race could have offered enormous rewards but also carried unnecessary risk. By withdrawing, Ingebrigtsen is effectively prioritising longevity over one more opportunity for immediate glory.

His message is clear: the comeback is underway, but it will not be rushed.

The 5,000m victory has given Ingebrigtsen confidence, momentum and perhaps, most importantly, proof that his body can once again handle elite competition.

Now comes the harder part — knowing when to stop.

With 2027 already firmly in his sights, the Norwegian has chosen recovery over risk. And after everything he has endured, that could ultimately prove to be one of the most important decisions of his comeback.

Jakob Ingebrigtsen is not walking away from the sport. He is protecting his future in it.
