Over the past decade, training for the heat has gone from a nice-to-have to an absolute necessity for top runners. Professor Chris Minson is attempting to perfect the science.

After a few pleasant hours sitting in the sun watching the Prefontaine Classic in Eugene, Oregon last month, I headed down into the bowels of Hayward Field for a grueling test for running in the heat. Chris Minson, a professor of human physiology at the University of Oregon, had invited me to try the heat adaptation protocol he has developed for elite athletes from the university and from local pro teams like the Bowerman Track Club. I’ve written about Minson’s research several times, so experiencing the protocol first-hand seemed like a good idea… at the time.

Heat is a big deal in sports these days, and it’s only getting bigger. In recent years we’ve had major events like the world track and field championships in insanely hot places, like Qatar, where the marathons had to be started at midnight. But summertime in Eugene (where the Olympic Track Trials will take place later this month) and Paris (where the Olympics will be held) can also be sizzling. Over the past decade, heat preparation has gone from a nice-to-have to an absolute necessity for top athletes. The details of how to prepare remain more art than science, though, so I was interested to see how Minson put theory into practice.

Back in the 1920s and 1930s, scientists developed the first heat adaptation protocols for workers in South Africa’s sweltering gold mines. The gold standard for heat adaptation evolved from that work: spend at least an hour a day exercising in hot conditions, and after 10 to 14 days you’ll see a bunch of physiological changes. Your core temperature will be lower, your blood volume will be higher, you’ll begin sweating and dilating your blood vessels at a lower temperature threshold, you’ll sweat more, and so on. Put it all together and you’ll be able to stay cooler and run faster in hot conditions.

In fact, there’s even evidence that this type of heat adaptation can make you faster in moderate weather, perhaps as a result of the extra blood plasma. In the lead-up to the 2008 Olympics, Minson was working with American marathoner Dathan Ritzenhein, helping him prepare for the expected hot conditions in Beijing. But he started to worry about what would happen if it wasn’t hot: would all the heat training actually make Ritzenhein slower? Minson and his colleagues ran a study to find out; the results, which they published in 2010, suggested that heat adaptation helps even in cool conditions. That’s the study that really kicked interest in heat training into higher gear.

The problem with the classic approach, though, is that training for an hour in hot, muggy conditions is exhausting. If you’re trying to do a hard workout, you won’t be able to hit the splits you want. If you’re trying to do an easy run, it’s going to take more out of you than it usually does, potentially compromising your next hard workout or raising your risk of overtraining. So how do you get the benefits of heat adaptation without tanking the rest of your training plan?

Minson’s Exercise & Environmental Physiology Lab at the University of Oregon, which he co-runs with fellow physiologist John Halliwill, is located in the Bowerman Sports Science Center, a state-of-the-art facility located under the northwest grandstand of Hayward Field. The key piece of equipment, for my purposes, is an environmental chamber that can take you down to 0 degrees Fahrenheit or up to 22,000 feet of simulated altitude, deliver simulated solar radiation, or blast you with wind. For my heat run, Minson set the dials to 100 degrees Fahrenheit and 40 percent humidity.

Earlier that day, Minson had given me a thermometer pill to swallow, which would enable him to wirelessly track my core temperature as the run progressed. “I’ll need that back,” he warned me, poker-faced. Fortunately, he was joking.

Before I entered the chamber, I peed in a cup so that Minson could check my urine-specific gravity, the ratio of how dense your urine is compared to water. I clocked in at 1.025, marginally above Minson’s threshold of 1.024 for mild dehydration. I blame it on having spent a few hours sitting in the sun watching the track meet. Then he checked my weight, so that he’d be able to figure out how much I sweated during the test.

When I stepped into the chamber, wearing nothing but shorts and running shoes, I could feel the blast of heat, but it wasn’t too oppressive—like a really hot day at the beach but under an umbrella. I started with a five-minute warm-up at a slow pace, gradually ramping up until I hit 7:30 mile pace. Then the formal protocol started: 30 minutes at that pace.

The pace was self-chosen; Minson refused to tell me the pace I “should” run. The goal was to settle in at an effort that I could comfortably maintain for half-an-hour, and that would get me hot enough to trigger adaptations—a core temperature of about 101 degrees Fahrenheit is thought to be about right—without overshooting and roasting myself. Most of the elite runners he works with end up choosing paces between 7:00 and 8:00 per mile. I slotted myself in the middle of that range—which, let’s be honest, was a dumb thing to do for an aging non-elite runner.

Still, the running itself felt easy to me. Every five minutes or so, Minson had me rate my perceived effort on the Borg scale, which runs from 6 to 20, and also rate how hot I felt. For this, he used his own 0 to 10 thermal scale.

I started out at the effort of 10 (“very light”) and thermal sensation of 3 (“warm”). After 15 minutes, my effort had crept up to 12 (“somewhat hard”), but my thermal sensation was still 3. By this point I was sweating up a storm, watching with interest as my splatters of sweat made a distinctly asymmetric pattern on the treadmill’s control panel. (Clearly I needed to visit the biomechanics lab down the hallway to sort out my stride asymmetries.)

In the latter part of the test, my sweat rate seemed to drop—not a great sign, since it could signal dehydration. My effort topped out at 13, but my thermal sensation crept up to 4 (“very warm”), then 5 (“slightly hot”), then 6 (“somewhat hot”). I still felt under control, though. Then the test ended, and Minson ushered me off the treadmill, into the next room, and into the hot tub, where he asked me to submerge myself up to my neck. The water was set to 104 degrees Fahrenheit, and it was awful. My thermal sensation immediately spiked up to 8 (“very hot”) and then 9 (“miserably hot”).

The odd thing is that the water was basically the same temperature as I was. My core temperature had crept up to 103.2 degrees towards the end of the run, and hit 103.7 shortly afterward. The water wasn’t warming me up in any significant way, but it was robbing me of the superficial perception of coolness that I got from air currents and the evaporation of sweat. It’s a good reminder of why cooling techniques like ice towels or simply dumping water on your head can be valuable: they can dramatically change your perception of how hot you are.

Sitting in that hot tub wasn’t fun, but it’s a key tool for Minson in his efforts to help athletes adapt to heat without interfering with their normal training. It extends the period of thermal stress without trashing their legs. A half-hour easy run, even in hot conditions, isn’t that draining for a well-trained athlete. At least, it’s not supposed to be.

After I’d had a cold shower and chugged a few bottles of sports drink, Minson went over the results with me. The good news is that I hadn’t seemed very bothered by the heat. I’d sweated out 2.2 pounds of fluid, indicating a fairly high sweat rate of around 2 liters per hour. That suggests that I should already be reasonably well equipped to race in warm conditions.

The bad news, though, was that my numbers didn’t make sense. There are no “wrong” answers on a subjective scale, but mine were puzzling. As the test proceeded and my core temperature drifted over 100 degrees, I kept claiming that I felt merely 3-out-of-10 “warm.” That might mean that I’m immune to heat—but more likely, it suggests that I wasn’t properly attuned to my body’s condition. If you’re running in the heat but you’re totally oblivious to how hot you’re getting, that can be a recipe for disaster.

In fact, my subjective numbers were strikingly similar to those of an elite runner Minson has worked with—one who has struggled in the heat. Minson helped the athlete renormalize his heat perception, so that conditions he originally labeled as 3 out of 10 became a more realistic 5 or 6 out of 10.

The ability to accurately gauge how hot you are is important even in training, because those core temperature pills are about $70 a pop. Once athletes have a sense of how hot they should feel during heat adaptation runs, Minson has them judge their half-hour efforts by feel. If they start getting too hot—above 7 on the Minson Scale—they can turn a fan on in the heat chamber to avoid overheating. There’s no rigid schedule of when they do these heat runs: they fit them in around their other training and racing and travel plans.

In practice, of course, most of us don’t have access to a high-tech heat chamber and temperature-controlled hot tub. But studies in recent years have shown that you can use a variety of approaches to get your core temperature up: hot baths, saunas (Minson has one in his lab, and another in his backyard), overdressing during runs. The big-picture takeaway from Minson’s approach is that you can find ways of getting a heat stimulus without disrupting the rest of your training.

To do that, though, you need to be able to gauge when you’re getting overcooked. When I got back to my hotel room that afternoon, I realized that I was feeling wrung out, as if I’d done a long, hard workout rather than a half-hour jog. I’d missed the mark. I decided to take the next day off, and dreamed that night of Minson’s other recent research focus: ice baths.

The future of American distance running may have just announced itself.

Luke Surface, an 8th-grade student-athlete from North Raleigh Christian Academy in Raleigh, North Carolina, delivered a performance that stunned the track and field community after taking on some of the nation’s best high school runners at Nike Outdoor Nationals.

Competing at the legendary Hayward Field in Eugene, Oregon — one of the most iconic venues in American distance running — Surface lined up in the boys championship 5,000 meters against a field dominated by high school seniors, including several athletes preparing to compete at the NCAA Division I level.

Despite being one of the youngest runners in the race, the 14-year-old held his own against the elite competition, finishing eighth in an incredible 14:25.88. The performance set a new national middle school record, averaging approximately 4:39 per mile for more than three miles.

That kind of time is fast enough to win many high school state championships across the United States and meets qualifying standards for several major NCAA Division I conference competitions — a remarkable achievement for a runner who has not yet entered high school.

But Surface’s historic 5,000m performance was only the latest chapter in a season filled with record-breaking moments.

Earlier in May, he clocked 8:52.03 for 3,200 meters at the NCISAA Division I State Championships in North Carolina, breaking another national middle school record. His converted two-mile time of 8:55.12 surpassed the previous world-best mark for a 14-year-old age group, previously held by Vincent Recupero.

During the previous cross-country season, Surface also made headlines when he ran 15:12 at the adidas XC Challenge, finishing second while competing against runners who were several years older.

Across cross country, two miles, and the 5,000 meters, Surface has continued to prove that his talent is far beyond his age group. While he still has four years of high school competition ahead before reaching the college level, his performances have already placed him among the most exciting young distance runners to watch.

The American high school 5,000-meter record currently stands at 13:32, set by Lex Young in 2023 — a mark Surface is not yet close to challenging. However, his remarkable progression at such a young age has caught the attention of the running world, with many eager to follow how far his extraordinary journey can go.

For now, Luke Surface remains an eighth grader rewriting the record books — and his story is only beginning.

DOHA, Qatar – Ethiopian distance running is once again making a powerful statement on the global stage. Following the Doha Diamond League meeting, Ethiopia has achieved a remarkable clean sweep of the women's 3000m/5000m standings, occupying all eight leading positions in one of the most competitive disciplines in world athletics.

Leading the charge is Likina Amebaw, who sits comfortably at the top of the rankings with 22 points. Close behind is fellow Ethiopian star Freweyni Hailu on 14 points, while Medina Eisa occupies third place with 12 points. The dominance continues through the rest of the leaderboard, with Senayet Getachew, Hawi Abera, Aleshign Baweke, Marta Alemayo, and Bernesh Dessie completing an extraordinary Ethiopian monopoly of the standings.

The achievement highlights Ethiopia's exceptional depth in women's distance running, where a new generation of athletes continues to emerge and challenge for global honours. Rather than relying on a single standout performer, Ethiopia has assembled a formidable squad capable of controlling races and collecting points across multiple Diamond League meetings.

While the current standings paint a picture of complete Ethiopian supremacy, the battle for the Diamond League title is far from over. Several meetings remain on the road to the season finale, leaving plenty of opportunities for rivals to close the gap and for positions within the Ethiopian contingent to shift dramatically.

For now, however, the spotlight belongs firmly to Ethiopia. The East African powerhouse has transformed the women's 3000m/5000m standings into an all-Ethiopian affair, sending a clear message to the rest of the world that the race for Diamond League glory will likely run through Addis Ababa.

The question now is whether Likina Amebaw can maintain her advantage and finish the season as the overall leader, whether Freweyni Hailu or Medina Eisa can mount a successful challenge, or whether another athlete will produce a late-season surge to rewrite the script.

One thing is certain: the road to the Diamond League Final promises a fascinating battle among some of the finest distance runners on the planet.

Kenyan athletics superstar and world champion Beatrice Chebet has officially entered a beautiful new chapter in her life after welcoming a baby boy.

The 26-year-old track sensation, born on 5 March 2000, has built a remarkable legacy as one of the greatest distance runners of her generation. Chebet is a world record holder in the 5000m, 10,000m and road 5km, with a career decorated by historic victories on the biggest stages.

She made history at the 2024 Summer Olympics by winning gold medals in both the 5000m and 10,000m, before achieving the same remarkable double at the 2025 World Athletics Championships. Her medal collection also includes a 5000m silver medal at the 2022 World Athletics Championships and bronze at the 2023 World Athletics Championships.

Beyond the track, Chebet has also dominated cross country, becoming a three-time world champion after winning the junior title in 2019 and senior titles in 2023 and 2024. She has also claimed major 5000m victories at the 2018 World U20 Championships, 2022 Commonwealth Games and the 2022 African Championships in Athletics.

Now, the Kenyan star is celebrating a different kind of milestone — becoming a mother.

Sharing the joyful news, Chebet introduced her newborn son with a heartfelt message filled with love and excitement:

“Tiny hands, tiny feet, and a love so big! A beautiful new chapter begins. Welcome to our world our sweet little baby boy!”

The arrival of her son marks a special moment away from competition, as the world champion embraces motherhood while carrying the pride of a nation that has watched her achieve greatness.

Messages of congratulations have poured in from fans and the athletics community, celebrating the new chapter for one of Kenya’s most successful athletes.

As Beatrice Chebet adds motherhood to her list of remarkable achievements, the champion now begins a new journey filled with love, joy, and unforgettable moments with her baby boy. 

Jake Wightman delivered a masterclass in championship racing as he surged to the men's 800m title at the UK Athletics Championships, holding off a determined challenge from Ben Pattison in a thrilling finish.

In a race defined by patience, positioning, and precise execution, Wightman waited for the perfect moment to strike before unleashing his finishing kick down the home straight. The former world champion crossed the line in 1:45.40, just doing enough to edge Pattison and secure the national crown.

The contest lived up to expectations, bringing together two of Britain's finest middle-distance talents in a tactical battle where every move carried significance. With the pace controlled through the early stages, the field remained tightly packed, setting the stage for a dramatic final lap.

As the bell rang, the intensity immediately rose. Pattison looked poised to seize control and pushed hard in the closing metres, but Wightman's experience and race awareness proved decisive. Drawing on years of competing at the highest level, he maintained his composure under pressure and found the extra gear required to stay ahead when it mattered most.

The victory marks another significant chapter in Wightman's decorated career and serves as a timely statement of intent as the international season gathers momentum. More importantly, it showcased the qualities that have made him one of Britain's most respected middle-distance athletes — tactical intelligence, resilience, and an ability to deliver in the biggest moments.

For Pattison, the narrow defeat will provide encouragement rather than disappointment. His performance confirmed his growing status among Britain's elite 800m runners and highlighted the depth of talent currently thriving in the event.

But on this occasion, the spotlight belonged to Wightman. In a race where the margins were razor-thin, he executed his plan to perfection and walked away with the UK Athletics Championship title.

Remember the name Gout Gout.

At just 18 years old, the Australian sprint prodigy is already commanding global attention and fueling conversations about the future of track and field. In a sport constantly searching for its next superstar, Gout is rapidly emerging as one of the brightest talents the world has seen in years.

His latest statement came at the prestigious Ostrava Golden Spike meeting, where he stepped onto the track alongside some of sprinting's biggest names, including reigning world champion Noah Lyles. Far from being overwhelmed by the occasion, the teenager delivered a composed and confident performance, finishing third in the 150m in 14.96 seconds against two of the fastest athletes on the planet.

Yet impressive as that performance was, it is not the result that has the athletics community buzzing most.

Earlier this year, Gout stunned the sprinting world by clocking an astonishing 19.67 seconds for 200m, setting a new world Under-20 record. The performance instantly elevated him from promising prospect to genuine phenomenon.

What makes the achievement even more remarkable is the historical context. At the same age, Gout was faster than sprint legend Usain Bolt. Comparisons to the Jamaican icon are inevitable, not because records demand them, but because the raw numbers are impossible to ignore.

Of course, Gout's journey is only beginning. Like any young athlete, he still has room to grow, refine his craft, and gain valuable experience at the highest level. The road from teenage sensation to global champion is rarely straightforward.

But there is no denying the extraordinary potential that lies within him.

His speed, composure, and ability to perform under pressure have already marked him out as one of athletics' most exciting young stars. More importantly, he possesses the kind of talent that inspires belief that a new era of sprinting may be on the horizon.

The sport has always thrived on rivalries that capture the imagination of fans across the globe. With established champions such as Noah Lyles currently leading the way, the emergence of Gout Gout adds an intriguing new chapter to sprinting's future.

The next great rivalry may already be taking shape.

And one of its leading figures is still only a teenager.

For now, the message is simple: remember the name Gout Gout. The future is arriving faster than anyone expected.
