Records are falling and times are dropping. Is it the shoes, or something else?

Consider the Paris Diamond League meet in early June. Jakob Ingebrigtsen smashed the two-mile world best by more than four seconds, becoming just the second man to run back-to-back sub-four-minute miles. Then Faith Kipyegon notched her second world record in a row, outsprinting the reigning record-holder over 5,000 meters just a week after becoming the first woman under 3:50 in the 1,500 meters. Then, to cap the night, Lamecha Girma took down the steeplechase record.

It was a great night—but it was just one of many great nights that track fans have been treated to recently. A week later, at the historic Bislett Games in Oslo, eight men broke 3:30 for 1,500 meters in one race, setting a new record—including Yared Nuguse, who set a new U.S. best. Meet records fell in almost every event. At the collegiate level, an analysis by Oregon-based coach Peter Thompson shows that the number of middle- and long-distance runners hitting elite benchmark times has doubled, tripled, or in some events even quadrupled in the last two years. Earlier in June, four high-school boys broke four minutes for the mile in a single race, matching the total number of people who’d done it in history prior to 2011.

I could go on.

There are two main questions that arise from this buffet of speed. First, is it real? Are runners getting faster across the board, or are we just being fooled by the brilliance of a few individuals and random fluctuations in the depth of different events? Second, if it’s really happening, then why? The easy answer is, “It’s gotta be the shoes” (or, in this case, the super spikes), but does the data really back that up?

I don’t have any definitive answers at this point, but here are my thoughts on some of the possible explanations.

It’s easy to make an anecdotal case that runners are faster than ever. Backing that up with data isn’t quite as straightforward. If you look only at whether the top-ranked time in the world is getting faster or slower from year to year, any trends will depend on whether you happen to have a generational athlete in the event at a given point in time. The effect of an Usain Bolt is bigger than the effect of, say, a new shoe design. Even if you go deeper, the top ten times in any year often come from just one or two races that took place in exceptionally good conditions. So you’re better off looking farther down the list.

For example, here’s some data for the men’s 1,500 meters between 2009 and 2022, drawn from the World Athletics database. I’ve shown the first, tenth, 100th, and 1,000th ranked performers (not performances) for each year. The horizontal dashed lines show the average for 2009 to 2018. The first super spike prototypes had shown up on the circuit by 2019 at latest, and were widely available by 2021. The big spike of slower times in 2020 is because there were so few races due to the pandemic.

The number-one times don’t show any particular trend. The tenth-best times show a dip since 2021, but no bigger than the dip in 2014-2015 (which corresponded to two particularly fast races in Monaco). For the 100th and 1,000th best times, the pre-pandemic data finally starts to look more consistent, which makes the dip since 2021 more telling. The 1,000th-best performer is now 0.9 percent faster than the pre-pandemic average, and the 100th-best is 0.5 percent faster. This is smaller than the 1.3-percent estimate derived from lab testing of super spikes, but in the ballpark.

Here’s comparable data for the women’s 5,000 meters:

Again, the first- and tenth-ranked times fluctuate too much to draw any conclusions. The 100th and 1,000th places do show an apparent drop in the last few years, by 1.9 and 2.0 percent respectively—more than the lab estimate. There are lots of possible explanations for this discrepancy, including that the benefits of super spikes are reduced at faster speeds.

I’ll add one more graph just for context. Supershoes came to road running way back in 2016 (for prototypes) and became widely available by 2018. I think most observers agree that these shoes really have affected road-running times. So what does the comparable data show for, say, men’s marathon times? Here it is:

The data is confounded by the effects of the pandemic, particularly in 2020. Still, the post-supershoe improvement looks fairly similar to the track data. Compared to the 2009 to 2016 average, last year’s times were 0.7 percent faster at tenth, 1.6 percent faster at 100th, and 1.3 percent faster at 1,000th.

The conclusion I take from all this data? It does like there’s something going on, both on the track and on the roads. But it’s way less obvious in the data than I expected. My subjective feeling was that the last few years have seen records broken and times redefined at a totally unprecedented rate. I thought I’d see robust improvement of at least three or four percent. But that scale of change is not there, at least in the events I sampled.

So with that in mind, what explains the changes we do see?

My starting assumption is that any performance improvements we’ve seen in the last few years are because of the shoes. I’m not going to belabor that point here, because I’ve already written plenty on both road supershoes and super spikes.

But I do want to make one key point. The reason my prime suspect is the shoes is that we have direct laboratory evidence that both types of shoes improve running economy, by around 2 percent on the track and at least 4 percent on the roads (and, to complete the circle, lab evidence that improved running economy directly translates to faster race times). It would take some weird and hitherto undiscovered science in order for the shoes not to make us faster. In contrast, the other hypotheses that I’m going to discuss below may be compelling to various degrees, but all rely on some assumptions and guesses and hand-waving.

Here’s a sentence you wouldn’t have read prior to 2018, from Letsrun’s description of Kipyegon’s thrilling 1,500 world record in Florence: “Kipyegon sprinted away from the pacing lights with 200m to go, lengthening her gap from the green lights as she rounded the turn and entered the home straightaway.” I wrote about World Athletics’s introduction of Wavelight pacing lights when Joshua Cheptegei set the 5,000-meter world record in 2020, positing that more even splits could make a notable difference to times. Good pacing has been a hallmark of this year’s records too, all assisted by Wavelight.

Wavelight doesn’t factor in on the roads, but ever since Eliud Kipchoge’s sub-two marathon exhibitions, big-time marathons have devoted more attention to providing top-notch pacers for their elite runners. That has the double benefit of saving the mental effort of setting the pace, and of reducing air resistance. I think good pacing and drafting are both beneficial. But that can’t explain why the 100th and 1,000th performers seem to be getting faster, because Wavelight and paid rabbits are generally reserved for the front of the pack.

Freed from the tyranny of over-frequent racing during lockdowns, runners spent 2020 building up a massive base of endurance that has catapulted them to new levels. It’s even possible that, having learned their lesson, they’ll continue with this more patient approach to training. This theory has the disadvantage of being both unprovable and unfalsifiable. That doesn’t necessarily mean it’s untrue, but if performance levels don’t start regressing to their pre-pandemic means over the next few years, I’ll remain skeptical.

It’s the “big, sexy thing” in endurance training these days, as miler Hobbs Kessler put it in a recent interview: lactate-guided double-threshold training, as popularized by Norwegian Olympic champions Jakob Ingebrigtsen and Kristian Blummenfelt. As I explained in this article, the approach emphasizes high volumes of threshold training with very tight control on the intensity to avoid going too hard. Whether it’s objectively better than other training approaches remains to be seen—but it hasn’t yet been adopted widely enough to make a noticeable impact on the top-1,000 list.

In the past, when I’ve looked at broad trends in performance over time, one of the first factors I’ve considered is changes in drug availability or drug testing. It’s extremely noticeable (though of course not proof of anything) that long-distance track times took off like a rocket shortly after the introduction of EPO in the early 1990s. If you look carefully, you can find what seems to be the performance signature of various drug-related events like the introduction of EPO testing and, more recently, the implementation of athlete biological passports.

Is there something new on the scene over the last few years? Or are we still seeing the effects of pandemic-related disruptions in out-of-competition drug testing? I certainly hope it’s not the case, but you’d have to be amnesiac to discount the possibility entirely. Once again, the best counterargument is that the performance improvements are noticeable even at the 1,000th-best level—though perhaps I’m being naive.

As you can probably tell, I don’t think any of the alternative explanations I’ve offered so far hold water compared to my default assumption that it’s the shoes. But this last category is a little different. If you spend enough time arguing with people about why runners are getting faster, you’ll encounter a number of broad, hand-waving theories that are hard to substantiate but nonetheless sound reasonable.

For example, I can attest to the fact that the Internet has made training knowledge far more widely accessible than it was when I was a young athlete in the 1990s. Ideas and approaches (like the Norwegian model) are endlessly debated and dissected, and any student of the sport is exposed to multiple perspectives. (In contrast, when I arrived at university and found that the workouts were different from those I’d done in high school, I thought the world was ending.) This theory has been offered frequently over the last decade or more as an explanation for steadily improving U.S. high school times. Maybe it’s true more broadly: people everywhere simply know more about the principles of training, and are doing it better (or at least fewer people are doing really stupid training) compared to the past. Even if elite coaching was always pretty good, this creates a wider pyramid of prospective talent feeding into the elite coaches.

I also have the sense that the pendulum has swung away from sit-and-kick racing towards aggressive front-running. After the 2019 world championships, where super spikes first made headlines, I wrote an article about the unusually fast early paces of the races. Jakob Ingebrigtsen, the current king of the 1,500, is notable for running from the front and pushing the pace rather than relying on a finishing sprint—which likely helps explain why he led those seven other men under 3:30 in Oslo. If runners these days are more focused on running fast times rather than trying to win sprint finishes, it stands to reason that times would get faster overall.

And there are plenty of other theories out there—broader support for professional training groups, better nutrition and recovery, the inevitable march of progress, and some that I’ve undoubtedly missed completely. As I said at the top, I don’t know the answers, and I don’t think anyone else does either. Times do seem to be improving, but not as much as I would have guessed based on all the hype about recent record-breaking. The shoes almost certainly play some role—but if there’s some other secret sauce in there, it’ll be fun trying to figure out what it is.

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.

Valencia Half Marathon 2026 Entries

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.
