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.

Ethiopia’s Fotyеn Tesfay Haylu delivered one of the most remarkable women’s half-marathon performances ever seen on American soil on Sunday, powering to a commanding victory at the 2026 Buenos Aires Half Marathon in Argentina in 1:03:57.

Running with exceptional confidence and strength, Tesfay took control of the race and produced a superb solo performance to rewrite the event record. Her breathtaking run also carried historic significance, as she became the first woman to break the 64-minute barrier for the half marathon in the Americas, producing what is being celebrated as the fastest women’s half-marathon performance ever recorded on the continent.

The Ethiopian star was in a class of her own, crossing the finish line more than a minute clear of Turkey’s Nevin Can, who finished second in 1:05:06. Another Turkish athlete, Selin Can, completed the podium in third place with 1:05:11, as the leading trio all produced strong performances on the fast streets of Buenos Aires.

Kenya also featured prominently in the top positions, with Irene Jepchumba Kimais taking fourth in 1:06:04, followed by Sheila Chepkirui in fifth with 1:06:13. Magaret Akidor Ngathike finished sixth in 1:06:46, while fellow Kenyan Deborah Samum claimed seventh place in 1:08:32.

Brazil’s Nubia de Oliveira Silva was eighth in 1:11:13, while Argentina’s Sofia Luna and Dahyana Juarez rounded out the top 10 with times of 1:11:21 and 1:11:28, respectively.

Top 10 Women – 2026 Buenos Aires Half Marathon

1. Fotyеn Tesfay Haylu (Ethiopia) – 1:03:57

2. Nevin Can (Turkey) – 1:05:06

3. Selin Can (Turkey) – 1:05:11

4. Irene Jepchumba Kimais (Kenya) – 1:06:04

5. Sheila Chepkirui (Kenya) – 1:06:13

6. Magaret Akidor Ngathike (Kenya) – 1:06:46

7. Deborah Samum (Kenya) – 1:08:32

8. Nubia de Oliveira Silva (Brazil) – 1:11:13

9. Sofia Luna (Argentina) – 1:11:21

10. Dahyana Juarez (Argentina) – 1:11:28

For Tesfay, it was far more than a race victory. Her 1:03:57 performance was a statement of extraordinary quality, combining speed, endurance and remarkable solo running to produce a landmark result in Buenos Aires. In a race that will be remembered for years to come, the Ethiopian did not simply win—she redefined what was thought possible for women’s half-marathon running in the Americas.

Ethiopia’s Yomif Kejelcha produced one of the most extraordinary performances in road racing history on the streets of Buenos Aires, Argentina, reclaiming the half marathon world record with a sensational 56:51 performance at the 2026 Buenos Aires Half Marathon.

The former world record-holder delivered a breathtaking exhibition of speed and endurance to take 29 seconds off the previous pending mark of 57:20, set by Uganda’s Jacob Kiplimo and takes a huge chunk from his own former official world record. Kejelcha's new performance is pending the standard ratification procedures, but if officially ratified, it will return the world record to the Ethiopian star and mark another remarkable chapter in the evolution of the event. 

Kejelcha's achievement is particularly significant because the 57-minute barrier had already been broken before. Jacob Kiplimo had previously run under 57 minutes, clocking 56:42 that was not ratified demonstrating that the once-unthinkable barrier was possible. Kejelcha, however, has become the second man to run under 57-minute barrier who now returns to the top of the all-time rankings with another historic performance in Buenos Aires.

The Ethiopian's race was remarkable not only for the final time but also for the way he built his performance. He covered the opening five kilometres in 13:44 before reaching 10km in 27:18. Rather than slowing, Kejelcha accelerated through the middle stages, passing 15km in 40:39 and 20km in 54:02 as he continued to push the limits of elite road racing.

By the time he reached the finish line, Kejelcha had completed the race at an extraordinary average pace of approximately 2:42 per kilometre, producing one of the most astonishing sustained efforts ever witnessed in distance running. His stunning run sent a powerful message to the athletics world and further strengthened his status as one of the most formidable distance runners of his generation.

Behind the record-breaking champion, Ethiopia completed a dominant clean sweep of the men's podium. Tadese Worku Gebresilase claimed second place in 59:18, while Bereket Nega Batebo secured third in 1:00:17, giving Ethiopia a memorable one-two-three finish in the Argentine capital.

Kenya’s Jonathan Kipkoech Kamosong finished fourth in 1:00:20, followed by compatriot Simon Maywa in fifth with 1:00:55. Argentina’s Ignacio Erario gave the home supporters plenty to celebrate with an impressive sixth-place finish in 1:00:57, breaking the one-hour barrier in front of an enthusiastic local crowd.

Dillon Kipyeko of Kenya finished seventh in 1:01:07, with Robert Kiprop Koech eighth in 1:02:01. Mexico’s Julio Ortiz Ponce took ninth place in 1:03:17, while Colombia’s Jimmy Gómez completed the top 10 in 1:03:34.

The Buenos Aires Half Marathon will now take its place in the history books as the scene of a truly extraordinary breakthrough. For Kejelcha, this was more than just another victory. It was a spectacular return to the top, reclaiming a world record he had previously held and once again rewriting the limits of the half marathon.

The 56:51 performance remains pending ratification, but Yomif Kejelcha's run has already delivered one of the defining moments in the history of road racing.

Kenya delivered another commanding display of distance-running excellence at the Antrim Coast Half Marathon, with Isaia Lasoi leading a memorable Kenyan clean sweep of the men's podium in a race packed with world-class performances.

Lasoi emerged victorious after a thrilling battle at the front, crossing the finish line in a superb 58:26 setting a new course record. His winning performance underlined his strength and speed over the half-marathon distance, but he was made to work all the way by fellow Kenyan Daniel Mateiko, who finished just three seconds behind in 58:29 after an electrifying duel for the title.

The contest between the two leaders produced one of the standout moments of the race, with both athletes pushing deep into elite territory as they fought for victory. In the end, Lasoi found just enough to secure the win, while Mateiko's narrow defeat highlighted the remarkable depth and quality of Kenya's leading distance runners.

Vincent Kipkorir completed the Kenyan sweep, taking third place in 1:00:38 to ensure that all three places on the podium belonged to Kenyan athletes. Samwel Chebolei added further Kenyan strength to the results, finishing fourth in 1:01:01, while Amos Langat was also among the leading finishers.

The international field featured several prominent names. Australia's Jimmy Whelan produced a strong run, while Ethiopia's Yismaw Dillu featured among the front group. American marathon star Galen Rupp also delivered a notable performance, clocking 1:01:29 in another competitive outing for the experienced distance runner. Former world-class track and road athlete Edward Cheserek was also among the top finishers.

Lasoi's 58:26 victory, however, was the defining performance of the day. Together with Mateiko and Kipkorir, he gave Kenya a perfect podium and another emphatic reminder of the country's extraordinary strength in elite road running.

The Antrim Coast Half Marathon once again provided a fast, competitive stage for some of the world's finest distance runners, but when the decisive moments arrived, it was Kenya that owned the podium.

One of the most iconic milestones in the history of ultramarathon running is drawing closer, with entries for the historic 100th edition of the Comrades Marathon set to open on Tuesday, 25 August 2026.

The Comrades Marathon Association has officially announced a detailed entry process for the 2027 race, which will unfold in three stages and give runners around the world the opportunity to secure their place in what promises to be one of the most significant editions ever held of The Ultimate Human Race.

The announcement followed the official launch of the 2027 Comrades Marathon on Wednesday, 19 August, when the centenary campaign, “The Greatest Story Ever Run,” was unveiled alongside a special logo created exclusively for the landmark 100th edition.

The launch also revealed several major highlights for the Centenary Race. The historic event will take place on Sunday, 13 June 2027, and will be a Down Run, with 28,000 places available. The entry process will include a ballot, while the race will offer a record R8.919 million in prize money. Organisers have also set an ambitious goal of raising R10 million for the Amabeadibeadi charities, adding an important charitable dimension to the centenary celebrations. One of the defining moments of the launch was the unveiling of the special Centenary mark, created to commemorate this extraordinary milestone in the history of the race.

The entry process begins on 25 August at 10:00 a.m. SAST, when entries open for Green Number runners, Yellow Number runners and Amabeadibeadi charity entrants.

The next phase follows on 2 September at 10:00 a.m. SAST, when entries open for Comrades Marathon Association members. This window will remain open for 72 hours or until the available entry allocation is filled, with places offered on a strictly first-come, first-served basis.

For general entrants, the process will move to a ballot system. General entries open on 9 September at 10:00 a.m. SAST, with runners able to enter the ballot until it closes on 22 September at 4:30 p.m. SAST. The ballot draw is then scheduled to take place on 23 September.

Several other crucial dates will shape the road to the historic race. The substitution period will run from 15 to 31 March 2027, while 3 May 2027 is the final deadline for runners to submit their qualifying performances, seeding information and other required entry details.

To qualify for the 2027 Comrades Marathon, runners must complete a 42.2km marathon in under five hours between 15 June 2026 and 3 May 2027.

The journey will finally culminate on Sunday, 13 June 2027, when thousands of runners are expected to line up for the historic 100th edition of the Comrades Marathon.

The 2027 race will represent a remarkable moment for the legendary South African ultramarathon. For more than a century, the Comrades Marathon has captured the imagination of runners and spectators with its extraordinary test of endurance, determination and human spirit. Its centenary edition will celebrate the generations of athletes who have faced its demanding roads, conquered its challenges and helped build one of the world's most respected endurance events.

For runners dreaming of becoming part of this historic occasion, the road to Comrades 2027 is now clearly marked. From the opening of entries in August 2026 to race day in June 2027, every deadline will matter.

The Greatest Story Ever Run is preparing for its most historic chapter yet.

American sprint standout Sam Blaskowski is taking steps toward an international future with Poland after uncovering a powerful connection to his family's ancestral homeland.

The 23-year-old sprinter, who has established himself as one of the fastest Americans of his generation with a personal best of 9.89 seconds in the 100 metres, has begun the process of obtaining Polish citizenship with the aim of eventually representing Poland in international competition.

Blaskowski's connection to the country traces back through his great-grandparents, Franciszek and Julian Błaszkowski, who emigrated from Poland to the United States in 1905. Their journey more than a century ago has now opened an unexpected new chapter for their descendant, whose athletic ambitions could soon carry the Błaszkowski name back onto the international stage under Polish colours.

The sprinter has already received support from the Polish Athletics Association as he works through the citizenship and eligibility process. Should his transfer of allegiance be completed, Blaskowski could become a significant addition to Poland's sprint programme.

His credentials certainly make the prospect an exciting one. In addition to his sub-10-second speed over 100 metres, Blaskowski owns a personal best of 19.93 seconds in the 200 metres, demonstrating the kind of versatility that could prove valuable both individually and in Poland's 4x100m relay squad.

For Blaskowski, however, the move is about more than simply changing national colours. It represents an opportunity to reconnect with his family's heritage while pursuing his ambitions at the highest level of the sport.

With his sights set on becoming part of Poland's international sprint team and competing for relay medals, Blaskowski's journey from discovering his Polish roots to potentially representing the country of his ancestors could become one of the most fascinating allegiance stories in world athletics.

A century after Franciszek and Julian Błaszkowski left Poland for America, their family's story may now be coming full circle—this time at full sprint.
