You won’t freeze your lungs exercising outdoors this winter, but there are reasons to be cautious about inhaling extremely cold air

When an athlete reaches the podium despite a prior medical event—a cancer diagnosis, say, or a car accident—we consider it a triumph of the human spirit. When a bunch of athletes do so, and all of them have suffered the same setback, we can be forgiven for wondering what’s going on. According to the International Olympic Committee, roughly one in five competitive athletes suffers from exercise-induced bronchoconstriction, or EIB, an asthma-like narrowing of the airways triggered by strenuous exercise. The numbers are even higher in endurance and winter sports. Puzzlingly, studies have found that athletes with EIB who somehow make it to the Olympics are more likely to medal. What’s so great about wheezing, chest tightness, and breathlessness?

The answer isn’t what you’re thinking. Sure, it’s possible that some athletes get a boost because an EIB diagnosis allows them to use otherwise-banned asthma medications. But there’s a simpler explanation: breathing high volumes of cold or polluted air dries out the airways, leading to an overzealous immune response and potential long-term damage. “It’s well established that high training loads and ventilatory work increase the degree of airway hyper-responsiveness and hence development of asthma and EIB,” explains Morten Hostrup, a sports scientist at the University of Copenhagen and lead author of a new review on EIB in the Scandinavian Journal of Medicine and Science in Sports. In other words, the athletes who train hard enough to podium are more likely to develop EIB as a result.

That trade-off might be worthwhile if it means competing at the Olympics. For those of us who simply enjoy spending our winter days vigorously exploring the outdoors, the risk of EIB remains mostly unknown territory. Activities with the highest risk involve sustained efforts of at least five minutes, particularly if they take place in cold or polluted air. Cold air doesn’t hold much moisture, so it dries the airways. This affects skiers, runners, and triathletes, among others. Indoor environments like pools and ice rinks are also a problem, because of the chloramines produced by pool water and exhaust from Zambonis. As a result, swimmers, ice skaters, and hockey players are also at elevated risk of EIB. Over time, repeated attacks can damage the cells that line the airways.

Unfortunately, many athletes develop symptoms of EIB without realizing the underlying problem. After all, the feeling that you can’t catch your breath is pretty much written into the job description of most endurance activities. But starting in the 1990s, sports scientists began to suspect that top athletes had more breathing problems than would be expected. Before the 1998 Winter Games, U.S. Olympic Committee physiologists examined Nagano-bound athletes to see whose airways showed abnormal constriction in response to arduous exercise. Almost a quarter of the athletes tested positive, including half the cross-country ski team.

One reason EIB often flies under the radar is that the usual diagnostic workups aren’t challenging enough to provoke an attack in conditioned athletes. Among the accusations against disgraced coach Alberto Salazar was that he showed athletes how to fool EIB tests to get permission to use asthma meds. “He had a specific protocol,” star 5,000-meter runner Lauren Fleshman told ProPublica in 2015. “You would go to the local track and run around the track, work yourself up to having an asthma attack, and then run down the street, up 12 flights of stairs to the office and they would be waiting to test you.” Salazar certainly gave some shady advice, including encouraging Fleshman to push for the highest possible dosage of medication. But his tips for gaming the asthma test were similar to what USOC physiologists advocate, and an IOC consensus statement published last spring also concluded that more intense exercise challenges are better for diagnosing EIB in conditioned athletes. If you’re really fit, in other words, the rinky-dink treadmill in the doctor’s office isn’t going to push you hard enough.

If you do get an EIB diagnosis, your doctor can prescribe asthma medication, including inhaled corticosteroids like fluticasone and airway dilators like salbutamol. If you’re an elite athlete subject to drug testing, you’ll need to tread carefully, since some of those medications are either banned or restricted to a maximum dosage. Hostrup and his colleagues note that there’s also evidence that fish oils high in omega-3 fatty acids, vitamin C, and even caffeine might help reduce EIB symptoms. And on the non-pharmaceutical side, you can minimize the chance of an attack by doing a thorough warm-up of 20 to 30 minutes, including six to eight 30-second sprints. This can temporarily deplete the inflammatory cells that would otherwise trigger an airway-narrowing attack.

The best outcome of all, of course, is to avoid developing the problem in the first place. In 2008, I interviewed a Canadian military scientist named Michel Ducharme, who told me stories of cross-country skiers swallowing Vaseline in an attempt to protect their airways from the cold. This is a terrible idea on many levels—and, he assured me, totally unnecessary. Air warms up very quickly when you inhale it, so there’s no risk of freezing your throat tissue. But dryness is another question, and scientists have reconsidered whether some kind of protection—just not Vaseline—could be useful if you’re going hard on cold days.

One option is a heat-and-moisture-exchange mask, which warms and moistens the air you inhale. A company called AirTrim makes them with a range of levels of resistance for training or racing. Several studies have found that this type of mask seems to reduce EIB attacks. Research by Michael Kennedy at the University of Alberta found that EIB risk increases significantly when temperatures drop below about five degrees Fahrenheit. The precise threshold depends on conditions and individual susceptibility, so if you start coughing or wheezing, that’s a sign your airways are irritated. If you don’t have a breathing mask, a scarf or a Buff over your mouth can offer a temporary solution.

Don’t take all this as a warning against getting outdoors in the winter. I live in Canada, so staying inside when it’s below five degrees Fahrenheit would be a death sentence. But I’m no longer as macho about the cold as I used to be. I wear puffy mittens and merino base layers, and when my snot starts to freeze I cover my mouth and nose. Athletes with EIB may do better than their unimpaired peers at the Olympics, but that’s one edge I can do without.

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.
