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.

At 67, Canadian runner Pete Benson is preparing to take on one of the most extraordinary endurance challenges in marathon running: completing seven marathons across seven continents in just seven days while raising money for a cause that reaches far beyond the finish line.

Hailing from Grand Manan, New Brunswick, Benson is set to participate in the Great World Race, an ambitious event that combines the physical demands of marathon running with a demanding journey around the globe. The challenge will require him to complete seven full marathons, each covering 42.195 kilometres, while travelling between continents on a tightly scheduled itinerary.

The challenge is scheduled to begin on November 15, 2026, with pre-event activities expected to start around November 12. Benson's adventure will begin in Antarctica, where the icy terrain and harsh conditions will provide a formidable introduction to the week ahead.

The opening marathon is scheduled for Wolf's Fang in Antarctica, where Benson will face the unfamiliar and potentially unforgiving conditions of the frozen landscape. Reflecting on the prospect of running through the ice and snow, he admitted that the experience is intimidating.

"That's pretty, pretty scary in itself," he said. "Through the ice and snow."

From Antarctica, Benson will travel to Cape Town, South Africa, for his second marathon on November 16. The journey will then continue to Perth, Australia, on November 17, followed by Singapore on November 18. On November 19, he is scheduled to race in the Algarve, Portugal, before heading to Cartagena, Colombia, on November 20. The challenge will conclude in Miami, United States, on November 21.

The demanding itinerary will leave little time for conventional recovery. After each marathon, Benson will need to travel to the next destination, navigate changing time zones and prepare for another 42.195 kilometres. Managing fatigue, nutrition, hydration and sleep will be essential as he attempts to complete the seven races within a single week.

Benson described the unusual routine that awaits him, highlighting the relentless cycle of running and travelling that defines the challenge.

"We run the race, get back on the bus, back on the plane, head to the next one and away we go around the world," Benson said. "That plane becomes our hotel and restaurant for the week, pretty much."

Beyond the physical demands, Benson recognises that taking part in such an ambitious international adventure comes at a considerable financial cost. He describes running as a personal investment, one that has provided him with valuable experiences and opportunities to discover more about himself.

"It's certainly a want, not a need," he said. "Some people go on river cruises and other things that they spend their money on and I spend my money on running and I've learned a lot from it."

Despite the expense, Benson believes the experience is worth the investment.

"So I think the investment is worth it, but it is extravagant," he said.

However, his motivation extends beyond personal achievement. Benson is also using the challenge to raise money for a nonprofit organisation that funds clean-water projects in countries around the world. The fundraising initiative is voluntary and is not a requirement for participating in the event.

By connecting his running adventure to a cause with a tangible impact on communities, Benson hopes to give every kilometre a greater purpose. His effort demonstrates how an individual sporting challenge can also become an opportunity to support work that improves lives.

"I'm happy that there's a purpose behind every mile that I run," he said.

That purpose adds another dimension to Benson's ambitious undertaking. While the seven marathons will test his physical strength, mental resilience and ability to recover between races, his fundraising mission will allow him to contribute to efforts aimed at improving access to clean water around the world.

As November 15 approaches, Benson is preparing for a demanding week that will take him from the ice and snow of Antarctica to the streets of Miami, with five other destinations in between. Each marathon will bring a new test, requiring careful preparation, determination and the ability to keep moving forward despite accumulating fatigue.

At 67, Benson is setting out to complete an extraordinary endurance challenge while supporting a cause beyond himself. Seven marathons, seven continents and seven days will test his limits, but his journey will carry a purpose that extends far beyond the finish line.

Australian endurance athlete Mick Marshall has achieved an extraordinary milestone at the 2026 Marine Corps Marathon in Washington, D.C., setting a world record for the fastest marathon completed on crutches after crossing the finish line in an incredible 5:35:50.

Representing Altra as an elite athlete, Marshall demonstrated remarkable determination and perseverance throughout the 26.2-mile (42.195-kilometre) race, turning one of the world's most celebrated marathon events into a stage for an inspiring display of human resilience.

Completing a marathon is a demanding physical challenge for any athlete, requiring months of preparation, mental strength and the ability to push through fatigue. Covering the same distance on crutches presents a different set of challenges, placing considerable demands on the upper body, coordination and endurance. Marshall's achievement highlights the dedication required to overcome obstacles and pursue goals that many might consider beyond reach.

The Marine Corps Marathon, renowned for its patriotic atmosphere, enthusiastic spectators and scenic course through the nation's capital, provided a memorable setting for the record-breaking performance. As thousands of runners pursued their own finish-line goals, Marshall carved out a special place in the event's history with his remarkable effort.

Beyond the record itself, Marshall's achievement carries a message that resonates far beyond the running community. Every movement toward the finish line required determination, patience and an unwavering commitment to the challenge before him. His performance is a reminder that greatness is not measured solely by how quickly someone reaches a destination, but also by the courage it takes to pursue a goal despite the difficulties along the way. For aspiring athletes and anyone facing personal challenges, his accomplishment offers a powerful lesson in perseverance, self-belief and the importance of refusing to give up when the journey becomes difficult.

His performance also serves as a reminder that marathon running is about far more than finishing times and podium positions. It is a test of courage, commitment and the willingness to redefine personal limits. Marshall's accomplishment demonstrates that the spirit of distance running extends beyond conventional expectations, inspiring athletes and spectators alike to reconsider what is possible through determination and hard work.

Marshall's remarkable run also reinforces the inclusive spirit of distance running, where the finish line belongs to everyone willing to take on the challenge. Whether competing for a championship, chasing a personal best or simply striving to complete the distance, every runner has a story worth celebrating. By setting a world record on crutches at one of America's prominent marathon events, Marshall has added an unforgettable chapter to that story, encouraging others to look beyond perceived limitations and pursue their ambitions with renewed confidence.

For Marshall, the 5:35:50 finish represents more than a time on the clock. It marks an extraordinary personal achievement and a moment that celebrates perseverance, resilience and the determination to keep moving forward. His performance has brought renewed attention to the remarkable possibilities within endurance sport and the many different ways athletes can challenge expectations.

Marshall's achievement at the Marine Corps Marathon stands as a powerful testament to the human spirit, demonstrating that success is not always about having the easiest path, but about finding the strength to keep going. His 5:35:50 performance is a reminder that the finish line can represent much more than the completion of a race: it can symbolise courage, possibility and the extraordinary things people can accomplish when they refuse to give up.

The 23rd edition of the Standard Chartered Nairobi Marathon delivered a spectacular celebration of endurance, determination and competitive excellence on Sunday, October 25, 2026, as Abraham Kiptum and Mercy Kandie Rotich claimed the men's and women's 42km titles in a memorable showcase of Kenyan road-running talent.

With thousands of runners taking to Nairobi's Southern Bypass, the full marathon provided a compelling test of physical strength, tactical discipline and mental resilience. For the elite athletes at the front, every kilometre presented an opportunity to gain an advantage, while the demanding distance required unwavering concentration from the starting gun to the finish line at Uhuru Gardens.

In the men's race, Kiptum produced an impressive performance to secure victory in 2:10:35, narrowly missing the course record by just 23 seconds. The 37-year-old Kenyan demonstrated his experience and endurance throughout the contest, ultimately establishing himself as the strongest performer over the 42.195-kilometre distance.

Kiptum's victory was particularly significant given his recent return to competitive marathon running. The athlete from Kapsabet had continued rebuilding his career and arrived in Nairobi following victory at the CRDB International Marathon in Dar es Salaam, Tanzania, in August. His latest triumph provided another encouraging chapter in his return to the forefront of distance running.

The men's contest produced an exceptionally close battle for the remaining podium positions. Fellow Kenyan Amos Kipkemoi Cheruiyot finished second in 2:10:37, just two seconds behind the champion, while Mark Kibiwott secured third place in 2:11:05.

Dismas Kiplimo finished fourth in 2:11:15, followed by Henry Kiprono Togom, who completed the top five in 2:11:55. The depth of the leading performances underlined the quality of competition on a morning when the front-runners pushed each other towards impressive finishing times.

Kiptum's performance also highlighted the importance of consistency and preparation in marathon running. Having invested months in training, the experienced Kenyan delivered when it mattered most, navigating the course with the composure required to emerge victorious against a competitive field.

The women's 42km race was equally captivating, with Mercy Kandie Rotich claiming the championship in 2:31:25 after a determined performance over the challenging distance.

Rotich demonstrated resilience and composure as the race unfolded, maintaining her challenge through the later stages before securing the victory. Her performance earned her a place among the latest champions of one of Kenya's prominent annual road-running events.

The battle for the women's title was decided by the narrowest of margins. Peris Jerono finished second in 2:31:27, only two seconds behind Rotich, while Ruth Wakabu completed the podium in 2:31:36. The three leading women finished within just 11 seconds of one another, providing a dramatic conclusion to the contest.

Shyline Jepkorir placed fourth in 2:34:55, while Dorothy Kipkilach finished fifth in 2:36:38, rounding out the leading performers in the women's division.

The narrow margins between the leading athletes reflected the unpredictable nature of marathon racing, where pacing, endurance and the ability to respond under pressure can determine the outcome after more than 42 kilometres of competition.

Beyond the podium battles, the full marathon represented a celebration of the determination that defines long-distance running. Every athlete who took on the distance faced the challenge of managing energy, overcoming fatigue and maintaining the mental strength necessary to reach the finish line.

The Southern Bypass provided the setting for these performances, with the runners navigating the Nairobi course before completing their challenge at Uhuru Gardens. The event brought together elite competitors and recreational athletes, united by the ambition to test their limits over the classic marathon distance.

The 2026 edition once again demonstrated the enduring appeal of road racing in Kenya, a country internationally recognised for producing exceptional distance runners. It also offered a platform for athletes to pursue personal ambitions, compete for prestigious honours and showcase the depth of talent within Kenyan athletics.

For Kiptum and Rotich, however, the day belonged to the pursuit of victory. Their respective performances secured them the coveted men's and women's marathon crowns, while the fiercely contested podium finishes ensured that the 42km races delivered the drama and excitement expected of a major road-running championship.

As the 23rd Standard Chartered Nairobi Marathon concluded, the achievements of the two champions stood out as the defining moments of the full-marathon competition, celebrating not only speed and endurance but also the preparation, perseverance and competitive spirit required to conquer 42.195 kilometres.

The true spirit of marathon running was beautifully displayed at the 2026 Mainova Frankfurt Marathon, where the celebration extended far beyond the elite athletes who crossed the finish line first. In a heartwarming tradition, the race's men's and women's champions waited inside the historic Festhalle Frankfurt to welcome the final finisher, reminding the world that every marathon journey deserves recognition.

As the final runner entered the magnificent venue, the atmosphere transformed into an unforgettable celebration. Confetti filled the air as music, dazzling lights and a red-carpet welcome created a moment usually associated with the sport's biggest stars. Standing alongside the champions, the last finisher received a hero's reception, demonstrating that the achievement of completing a marathon deserves to be celebrated regardless of finishing position.

Ethiopia's Jirata Lelisa Dinki, who won the men's race in an impressive 2:05:26, and compatriot Zeineba Yimer Worku, the women's champion in 2:19:45, were among those celebrating the final runner's remarkable achievement.

Their presence sent a powerful message about the values that make marathon running special. While elite athletes push the limits of human performance in pursuit of victory and fast times, thousands of other runners take on the same 42.195-kilometre challenge for deeply personal reasons. For some, the goal is to achieve a personal best; for others, it is to overcome adversity, fulfil a lifelong ambition or simply reach the finish line.

The final finisher's journey may have taken longer than that of the champions, but the determination required to keep moving forward deserves equal admiration. Every kilometre represents effort, sacrifice and perseverance, and crossing the finish line marks the successful completion of a challenge that demands both physical endurance and mental strength.

Frankfurt's special welcome captured an essential truth about distance running: a marathon is not only a race against the clock but also a personal battle against exhaustion, doubt and the temptation to give up. By waiting for the final runner, the champions helped ensure that the day's celebrations included someone whose achievement might otherwise have gone unnoticed.

In a sport often defined by world records, course records and podium finishes, this touching tradition offers a refreshing reminder that the value of a marathon cannot be measured by time alone. The fastest runners may make headlines for their performances, but every finisher has a story worth telling.

At the Mainova Frankfurt Marathon, the champions had already conquered their own challenges. Yet their decision to welcome the last runner created another memorable moment, showing that greatness in sport is measured not only by what athletes accomplish but also by the respect they show others.

Because when the final runner receives the same warmth, applause and celebration as the champions, the message is unmistakable: every runner matters, every finish line represents an achievement, and nobody should be left behind when it is time to celebrate.
