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.

The prospect of seeing one of athletics' biggest stars back on the track is growing stronger, with Jakob Ingebrigtsen reportedly targeting a return to competition later this summer following his recovery from Achilles tendon surgery.

According to comments made by his agent, Daniel Wessfeldt, in an interview with Norwegian media, the double Olympic champion could make his long-awaited comeback at one of three major European meetings in July. The leading options under consideration are the Monaco Diamond League on July 10, the Hungarian Athletics Grand Prix on July 14, and the London Diamond League on July 18.

For athletics fans, the possibility of Ingebrigtsen lining up in London would add another layer of excitement to an already highly anticipated Diamond League meeting. The Norwegian middle-distance sensation has become one of the sport's most dominant figures in recent years, collecting Olympic, world and European titles while consistently rewriting record books.

His 2026 campaign was put on hold after he underwent surgery on his Achilles tendon earlier this year, forcing him to focus on rehabilitation rather than competition. Since then, questions have surrounded when the 24-year-old would be ready to return to racing.

The latest update suggests that decision will largely depend on how his training progresses over the coming weeks. If recovery continues according to plan, July could mark the beginning of his return to elite competition ahead of the latter stages of the season.

A comeback at either Monaco, Budapest or London would immediately place Ingebrigtsen back among the sport's biggest storylines. Each meeting is renowned for producing world-class performances, and any appearance by the Norwegian would attract significant attention from fans eager to see how quickly he can regain top form after his injury setback.

While no final decision has been confirmed, the signs are increasingly positive. After months away from competition, Jakob Ingebrigtsen appears to be edging closer to a return, with London's Diamond League meeting emerging as one of the most intriguing possibilities on his road back to the track.

Should his recovery continue smoothly, athletics could soon welcome back one of its brightest and most influential stars.

What should have been the defining moment of Emad Bashir-Mohammed's young running career instead turned into one of the most talked-about controversies in American road racing this year.

The 23-year-old crossed the finish line first in the men's citizen's race at the prestigious Bolder Boulder 10K on Memorial Day in Colorado, stopping the clock at an impressive 29:50. His performance was not only a commanding victory but also one of the fastest winning times ever recorded in the event's long and celebrated history. Bashir-Mohammed finished eight seconds clear of his nearest challenger and appeared to have secured a breakthrough triumph.

For nearly two hours, he was the undisputed winner.

Then everything changed.

Race officials announced that Bashir-Mohammed had been disqualified after determining that he had started in the wrong wave. According to Bolder Boulder regulations, he had been assigned to the AA wave but lined up with the faster A wave, which began earlier. Event rules allow runners to move backward into a slower wave, but prohibit athletes from advancing into a faster one.

As a result, Bashir-Mohammed's victory was erased from the record books.

The citizen's title was subsequently awarded to Nickolas Scudder, who crossed the line second in 29:58. The promotion handed Scudder back-to-back citizen's race victories, while Bashir-Mohammed was left to grapple with the disappointment of losing a win he believed he had earned on the road.

The disqualification has since ignited widespread debate across the running community.

Bashir-Mohammed maintains that he did not intentionally violate the rules. He claims that after collecting his AA bib, he spoke with race personnel and was permitted to start with the A wave after presenting evidence of his recent performances. In a statement shared after the race, he expressed frustration over the decision, arguing that his goal was simply to compete against the strongest field available and produce the fastest time possible.

Race organizers, however, stood firmly behind their ruling. Officials stated that wave-assignment regulations are clearly communicated in pre-race information and reiterated during packet collection. They also noted that hundreds of participants are disqualified each year for moving into faster start groups, emphasizing that consistent enforcement is necessary to maintain fairness for all competitors.

The incident has divided opinion among runners and fans alike. Some believe the rules must be applied equally regardless of an athlete's finishing position, arguing that wave assignments are a fundamental part of race organization. Others feel the punishment is harsh, particularly if Bashir-Mohammed genuinely received approval to move up before the start.

What remains undisputed is the quality of his performance. On the roads of Boulder, Bashir-Mohammed demonstrated the fitness and speed required to outrun the field by a significant margin. Yet in road racing, crossing the finish line first is only part of the equation. Compliance with race regulations carries equal weight.

For Bashir-Mohammed, the day will be remembered as a painful lesson in the fine margins that can define elite competition. A remarkable run delivered a memorable victory, but a dispute over wave placement ultimately overshadowed the achievement, leaving behind a controversy that continues to fuel discussion throughout the running world.

A fast race, a costly administrative error, and a debate that may linger long after the finish-line tape has been packed away.

Audrey Werro announced her arrival as one of the early stars of the 2026 outdoor season with a commanding victory in the women’s 800 metres at the Rabat Diamond League, producing a performance that exceeded even her own expectations.

The Swiss middle-distance talent surged to victory in a brilliant 1:56.56, breaking the meeting record and delivering one of the fastest times recorded worldwide this season. In a race packed with quality, Werro displayed exceptional composure, confidence, and finishing strength to separate herself from the field and stamp her authority on the event.

What made the performance even more remarkable was the athlete's surprise at the level she had already reached so early in the campaign.

"I was not expecting such a strong start to the season," Werro admitted after the race.

The race unfolded at a relentless pace, but Werro remained perfectly positioned throughout. As the athletes approached the bell lap, she glanced at the clock and immediately sensed something special was within reach.

"When I saw the time at the bell, I felt really confident," she said. "I'm really happy with the Meeting Record and looking forward to the rest of the season."

Her confidence proved justified. Maintaining her rhythm over the final 400 metres, Werro powered down the home straight to secure the victory and rewrite the Rabat meeting record books in the process.

The performance sends an early warning to her rivals ahead of a season that promises major championships and high-profile Diamond League battles. Beyond the record-breaking time, Werro's display highlighted her growing maturity as a racer, combining tactical awareness with impressive speed and endurance.

With the outdoor season only beginning, the 1:56.56 clocking suggests that even faster times could be on the horizon. If Rabat is any indication, Audrey Werro may be poised for the biggest season of her career.

Her emphatic victory in Morocco was more than just another Diamond League win—it was a statement of intent from an athlete determined to challenge the world's best throughout 2026.

The city of Boston is set to welcome back one of its most celebrated champions as Kenya’s Sharon Lokedi headlines a world-class field for the 2026 B.A.A. 10K presented by Mass General Brigham Cancer Institute on June 21.

Fresh from another remarkable victory at the Boston Marathon in April, Lokedi returns to the streets of Boston and Cambridge carrying both momentum and confidence as she aims to defend the title she captured in dominant fashion last year.

The two-time Boston Marathon champion has developed a special connection with the historic race city. In 2025, she produced a course-record performance of 2:17:22 to win the Boston Marathon before returning this year to claim another victory in 2:18:51, the second-fastest winning time in the event’s storied history. Her success has cemented her status as one of the premier road runners in the world.

Lokedi will be making her first competitive appearance since her marathon triumph and arrives as the reigning B.A.A. 10K champion after clocking 31:39 over the challenging 6.2-mile course in 2025.

“Boston has become a very special place for me,” Lokedi said ahead of the race. “The atmosphere created by the fans and the community is unlike anywhere else. I’m excited to return and give everything I have to defend my title.”

The women’s race promises to be highly competitive. American Olympian Rachel Smith, who finished second at the Boston 5K in April, leads the domestic challenge. Kenya’s strong contingent includes African 10,000m champion Gladys Kwamboka, former B.A.A. 10K runner-up Stacy Ndiwa, and experienced road racer Viola Cheptoo. British Olympian Jessica Warner-Judd adds further international depth to a field packed with proven performers.

The men’s race is equally impressive, featuring elite athletes from 13 nations.

Ethiopia’s Dawit Seare enters as one of the leading contenders after capturing the 2025 Boston 5K title and bringing the fastest 10K personal best in the field at 27:21. Kenya will be represented by an accomplished group led by Alexander Mutiso, winner of the 2024 London Marathon and runner-up at last year’s New York City Marathon.

Patrick Kiprop also arrives in outstanding form after securing victory at the prestigious BolderBoulder 10K on Memorial Day, while Alex Masai returns looking to continue his strong record in Boston. Masai recently finished ninth at the Boston Marathon and has earned three top-ten finishes at the B.A.A. 10K.

Among the international stars making their mark is South Africa’s Adriaan Wildschutt, who makes his race debut after an impressive season highlighted by victory at the NYC Half Marathon in 59:30. Ethiopia’s Olympic bronze medallist Hagos Gebrhiwet adds further quality to the field, bringing a wealth of championship experience and previous success in Boston.

Canadian national 10K champion Andrew Alexander, two-time U.S. Olympian Hillary Bor, marathon standout Ryan Ford, and reigning USA 25K champion Andrew Colley complete a field stacked with talent and depth.

With defending champions, Olympic finalists, national champions and rising stars all converging on Boston, the 2026 B.A.A. 10K is shaping up to be one of the most competitive editions in recent memory. For Sharon Lokedi, however, the mission is simple: return to the city where she has repeatedly excelled and add another memorable chapter to her growing Boston legacy.
