Here's what to keep in mind about hydration supplementation at all elevations

When Lara Crawford stopped into her local vitamin and supplement store a few months ago, she was in search of something to alleviate her acid reflux, which causes a burning sensation in her chest and acid regurgitation. But the conversation quickly took a turn when a staff member learned Crawford wasn’t taking electrolyte supplements.

Crawford lives at 9,000 feet in the Colorado Rockies, a place considered to be high altitude. Even after living in the mountains for years, she never saw a need for additional electrolytes. However, the staff member told Crawford those who live at altitude tend to get dehydrated overnight—and suggested she start taking sports salts pills and a daily electrolyte powder.

“I thought those were just for ultra athletes or like serious athletes, but he told me everybody should be taking them,” Crawford says. He spoke so convincingly about their benefits that she decided to give the electrolytes and sports salts a try.

After using the sports salts in the morning and the electrolytes at midday for a few months, she noticed a moderate improvement in her acid reflux. However, the biggest change was in her face: She no longer woke up with dry, puffy eyes.

Spotting the meaningful difference, she wondered if the staff member was right. Was the shift due to her new electrolyte supplements? Maybe these weren’t just for endurance athletes after all. Perhaps even people who only engaged in moderate exercise still needed to supplement with electrolytes at altitude.

Vic Johnson, an Utah-based sports nutritionist who works with outdoor athletes, including ultra runners, cyclists, and triathletes, says that while we do lose more fluids at altitude, there’s nothing special about nighttime.

However, the electrolyte and hydration question, and how much each of us should be consuming each day, is a bit more complicated.

At higher elevations, your body has to work harder to get oxygen, which causes your breathing rate to increase. Since you lose water through respiration, this results in greater fluid loss. The air is also drier at altitude, which makes your sweat evaporate faster and causes additional fluid loss. Each of these factors contribute to your body losing more water than at sea level, requiring you to hydrate more frequently.

However, the longer you stay up in the mountains, the better it gets. Johnson says people who live at altitude are able to adapt to the lack of oxygen. Their bodies become more efficient, producing more red blood cells to carry oxygen through the body, which reduces the amount of fluid lost.

“It’s going to be pretty stressful on your body for a couple of weeks,” Johnson says, referring to spending time at elevation. “That’s the most crucial time to increase fluid intake. Then things will kind of regulate, and you won’t have to compensate quite so much.”

However, even longtime residents of high altitude towns—Crawford has lived at 9,000 feet for 29 years—typically need about a liter to a liter and a half more water per day (about four to six cups) than people living at lower altitudes. But hydration isn’t a one-size-fits-all prescription. Whether you’re in the mountains or at sea level, your fluid intake varies based on the weather, the amount you exercise, and your overall health.

To help his athletes find the amount of hydration they need, Johnson performs a sweat rate test. He starts by weighing them before they exercise. While they work out, he keeps track of the fluids they drink and any urine they lose. After they’ve finished, he weighs them again and plugs each data point into an equation to figure out how many milliliters of sweat per hour they lose. (If you’d like to try this for yourself, use a step-by-step guide to finding out your own sweat rate.)

It’s important to note that even once you’ve figured out your sweat rate, completely replacing your lost liquids isn’t necessarily the goal. It’s not bad to be slightly dehydrated and more hydration isn’t always the solution. For many, drinking to quench your thirst is sufficient. (Those in their 70s or 80s need to monitor their intake a bit more, because our thirst sensation can decrease with age.)

Electrolytes are electrically-charged minerals such as sodium, calcium, magnesium, and potassium that regulate your muscle contractions, keep you hydrated, and balance your pH levels. Every fluid and cell in your body has electrolytes, which aid the function of your nerves, muscles, brain, and heart. Electrolytes also manage the balance of fluids in your body’s cells and are lost through sweat and urine, or if you’re sick, through vomiting and diarrhea.

While electrolytes are essential, Johnson says most of us get all we need from food. “A normal, varied diet should provide you with plenty of electrolytes, even at altitude.” Johnson says, “For the recreational athlete, it’s honestly not that big of an issue.”

If you aren’t engaging in high-output endurance activities lasting longer than three hours, and if you’re eating a nutrient-dense diet with whole grains, legumes, vegetables, fruits, nuts, and seeds, Johnson says you should be getting enough electrolytes without needing additional supplementation. However, endurance athletes who engage in high-output endurance activities lasting longer than three hours have different hydration needs, and may find electrolyte powders and capsules are a good way to stay hydrated and keep their electrolytes balanced.

That doesn’t mean these supplements are the secret to unlocking a new PR. A 2020 study conducted by researchers at Stanford University found that electrolyte supplementation does not improve performance or protect against illnesses caused by a change in sodium levels, including exercise-associated hyponatremia (EAH).

If an endurance athlete wants to take in some sodium, Johnson recommends turning to salty foods, such as pretzels or even a peanut butter sandwich.

“For the most part, when our serum sodium levels drop, the body can usually take care of that and regulate that on its own,” he says.

So, if electrolyte supplementation isn’t really necessary for most people, why did Crawford see a noticeable difference in her face after months of supplementation?

The answer most likely lies in what Crawford took with the powder and capsules.

Before going to the supplement store, Crawford says she struggled to drink enough water. However, while doling out instructions for the supplements, the staff member instructed Crawford to drink a full bottle of water with her morning sports salts capsules (which contain sea salt, magnesium, and potassium) and to mix the flavored electrolyte powder with at least 16 ounces of water later in the day. The supplements provided the structure for her to consume more water, improving her overall hydration and reducing the puffiness in her eyes.

If you live at altitude and find it difficult to drink adequate fluids, a flavored powder might help. For most people, however—including serious athletes—drinking when you’re thirsty is usually enough.

Jakob Ingebrigtsen brought his remarkable 2026 season to a fitting close on home soil, winning the men’s street 1500m at the inaugural Runfest Norway in Sandnes on Friday.

Competing in front of an enthusiastic hometown crowd, the Olympic and world champion took control of the race from the early stages and maintained his authority through the finish, stopping the clock at 3:40.7.

Andreas Fjeld Halvorsen followed in second in 3:43.3, while Sigurd Tveit completed the podium in 3:47.8.

The unusual street race added another dimension to the occasion, with 273 runners taking part on the same road and sharing the course with one of Norway’s most accomplished distance runners. For the recreational participants, it offered a rare opportunity to compete alongside Ingebrigtsen in an event that brought elite athletics and mass participation together.

The victory also provided a fitting final chapter to a season that began with significant uncertainty for Ingebrigtsen. After undergoing major Achilles surgery in February, the Norwegian was forced to miss a substantial portion of the summer campaign as he worked his way back to full fitness.

His return, however, quickly developed into another championship-winning chapter. In Birmingham, Ingebrigtsen captured European 5,000m gold before adding another major title at the inaugural World Athletics Ultimate Championship in Budapest, where he won the 5,000m.

Those performances transformed what could have been a disrupted season into another year defined by championship success and a determined return to the highest level.

Now, with the Sandnes victory added to his 2026 record, Ingebrigtsen closes the year exactly where it began in spirit — overcoming adversity, rebuilding his form and once again competing at the front.

From Achilles surgery in February to major championship victories and finally a 1500m win before his hometown crowd, the Norwegian has given his 2026 season a memorable final scene.

Olympic 100m hurdles champion Masai Russell has announced her engagement to longtime partner Robert “Robbie” Springfield, adding a major personal milestone to the remarkable journey of one of America’s leading track and field stars.

Russell shared the news with her followers, revealing that Springfield had proposed and that she had accepted. Reflecting on their relationship, the Olympic champion described him as her best friend and expressed her excitement about spending the rest of her life with him.

The couple’s relationship dates back to their college years at the University of Kentucky, where both were student-athletes and competed in track and field. Russell established herself as a standout hurdler, while Springfield competed in the long jump, giving them a shared understanding of the demands, sacrifices and pressures that come with pursuing success in athletics.

Springfield has since transitioned from competition into coaching. A former collegiate long jumper, he is now part of the coaching staff at Morehead State University, where he works with the programme’s sprinters and jumpers.

Their relationship has developed alongside Russell’s rise to the top of the sport. The defining moment of her career came at the Paris 2024 Olympic Games, where she captured gold in the women’s 100m hurdles, securing her place among the sport’s Olympic champions.

Away from competition, Springfield has remained a familiar part of Russell’s journey, sharing in the demanding periods of training and competition that accompanied her pursuit of Olympic success. Their connection has consequently grown from a college athletics relationship into a long-term partnership.

The engagement now marks another significant chapter for Russell, this time away from the track. After reaching the pinnacle of her sporting career in Paris, the 100m hurdles champion is beginning a new phase of her personal life alongside a partner who has been part of her journey since their university days.

From competing on the same collegiate stage to building a future together, Russell and Springfield’s story has evolved alongside two careers shaped by track and field. The Olympic champion will now balance this new personal chapter with her continuing ambitions in athletics

The women’s race at the 2026 TCS Amsterdam Marathon is shaping up to be one of the most competitive editions in recent years, with a deep international field set to take on the fast Dutch course on Sunday, October 18.

At the centre of the contest will be four Ethiopian athletes who have already broken the 2:20 barrier, creating the prospect of a fascinating battle for victory and a possible assault on the course record of 2:16:52.

Defending champion Aynalem Desta will return to Amsterdam looking to retain her title after producing the biggest performance of her career at last year’s 50th edition. Desta won in a personal best of 2:17:37, establishing herself among the leading marathoners in the field and setting the benchmark for this year’s contenders.

Standing in her way will be fellow Ethiopian Meseret Belete Tola, a former Amsterdam champion who knows exactly what it takes to succeed on the course. Belete Tola captured the 2023 edition in 2:18:21, and her return adds another layer of experience and proven quality to an already formidable lineup.

The field also includes Mestawut Fikir Truneh, who arrives with an impressive marathon pedigree. Truneh finished runner-up at the 2024 Berlin Marathon in 2:18:48, demonstrating her ability to compete at the highest level on one of the world's major marathon stages.

Completing the quartet of sub-2:20 Ethiopians is Buze Diriba, whose personal best of 2:19:34 places her firmly among the leading contenders. With four athletes possessing credentials below 2:20, the race is likely to develop into a tightly contested battle from the opening kilometres.

The depth extends well beyond the leading quartet. Desi Jisa Mokonin, representing Bahrain, Yeshi Kalayu Chekole of Ethiopia and Nazret Weldu Gebrehiwet of Eritrea have all established themselves as serious marathon competitors with performances approaching the 2:20 mark.

Another major name to watch is Abeba Aregawi, the former 1500m world champion representing Sweden. Aregawi has successfully transferred her talents to the marathon and made headlines earlier this year by setting a Swedish national record of 2:23:12 on her debut. Her presence adds another intriguing dimension to an already high-quality field.

Amsterdam’s marathon course has consistently provided an opportunity for elite athletes to produce fast times, and this year’s women’s lineup has the depth to turn the race into a genuine test of both championship racing and outright speed.

With four athletes already inside 2:20, two former Amsterdam champions returning to the start line and several other accomplished marathoners ready to challenge them, the battle is expected to remain open deep into the race.

The ultimate target will be the Amsterdam women’s course record of 2:16:52. Whether the leading contenders can threaten that mark remains to be seen, but the quality assembled for October 18 ensures that the record will be firmly in the spotlight when the race reaches its spectacular finish inside the Olympic Stadium.

The 2026 Valencia Half Marathon is shaping up to be a thrilling contest of speed, endurance and tactical brilliance, with some of the world’s finest road runners set to converge in Spain on October 25.

Kenya’s Daniel Ebenyo and Alex Matata will be among the leading contenders, facing a formidable Ethiopian challenge spearheaded by Jemal Yimer and Tadese Worku. The field also features Rodrigue Kwizera, who boasts the fastest personal best among the leading entrants at 58:16.

Ebenyo arrives with a personal best of 59:04, placing him firmly among the athletes capable of sustaining a demanding pace over the 21.1-kilometre distance. Matata, who owns a 59:11 best, adds further Kenyan strength, while Andrea Kiptoo brings another sub-60-minute credential to the race.

Yimer has already established himself as one of the fastest athletes in the field with a 58:33 personal best, while Worku has clocked 58:35. Kenya’s Owen Korir, with a best of 58:58, further underlines the remarkable depth of the men's lineup.

Kwizera, who finished second in Valencia last year, leads the field on paper and will be seeking another standout performance on the famously fast Valencia course. With several athletes carrying sub-60-minute credentials, the race has the ingredients for an aggressive battle from the opening kilometres.

Beyond the headline names, the men’s field is deep and highly competitive, bringing together a strong collection of experienced international athletes with proven ability over the half-marathon distance. With so much quality packed into the lineup, the race promises an intriguing battle in which tactics, endurance, positioning and finishing speed could all play a crucial role in determining the eventual champion.

Yet personal bests will count for little once the gun goes off. The title could ultimately be decided by patience, positioning and the ability to respond when the pace begins to rise in the closing stages. Every surge, every tactical move and every second saved could prove decisive on the road to the finish.

With Kenya, Ethiopia and Spain represented by athletes of exceptional quality, Valencia promises a high-octane men's showdown in which the leaders are likely to be separated by only a handful of seconds. The final kilometres could provide the defining moments of a race packed with speed, ambition and anticipation.

On October 25, the question will be simple: who has the strength to command the streets of Valencia and claim the coveted half-marathon crown?

 

April 19, 1982. The Boston Marathon unfolded under unusually warm, sunny conditions, and by the closing stages, the race had become a private battle between two very different American runners: Alberto Salazar, already one of the biggest names in distance running, and Dick Beardsley, the Minnesota runner who had emerged as a serious marathon contender.

For roughly nine miles, from the Newton Hills toward the finish, Beardsley did much of the leading, with Salazar tucked close behind. Neither man could shake the other. They ran deep into Boston locked together, trading surges and refusing to surrender an inch as the crowds along the course grew louder.

Salazar finally made his decisive move with less than a mile remaining. He opened a small gap, but Beardsley refused to disappear. The Minnesota runner chased him through the final streets, closing again as they approached the finish.

Then came the final sprint.

Salazar held his form and reached the finish first in 2:08:52, with Beardsley only two seconds behind in 2:08:54. It was an extraordinary result: both men broke 2:09 in the same Boston Marathon, and both shattered the previous course record.

The race became known as the “Duel in the Sun,” and it remains one of the most celebrated head-to-head battles in Boston Marathon history. Beardsley had not won, but his performance established him as one of America's elite marathoners.

For Salazar, however, victory came at an enormous physical cost. Immediately after crossing the finish line, he collapsed and required emergency treatment, including several litres of intravenous saline. The combination of heat, dehydration and an all-out effort had pushed his body to the limit.

Salazar's marathon career would never again produce quite the same kind of performance. His celebrated 1981 New York City Marathon victory had produced what was initially considered a world record, although the course was later found to be short. His Boston triumph therefore became one of the defining victories of his career.

Beardsley's story would take an even more difficult turn. Injuries disrupted his career, and after returning to the highest level, he suffered a devastating farm accident in 1989. Further accidents, surgeries and severe physical pain followed, eventually leading to a long battle with painkiller addiction.

He eventually overcame that struggle and transformed the darkest chapters of his life into a story of recovery, resilience and redemption.

That is what makes the 1982 Boston Marathon more than a two-second victory.

For one extraordinary afternoon, Salazar and Beardsley produced a marathon duel in which neither man was willing to give way. One crossed the finish line first. The other finished only two seconds behind him.

Two seconds separated them at Boston. Decades later, their legendary duel remains one of the greatest chapters in marathon history.
