- aucisson_masque 5mo agoHe is the Armstrong of running, popularity wise and other things...
- stockresearcher 5mo ago3 people beat the previous world record in this race! This is some combination of improved tech and extraordinarily good weather. London is a fast course. Let’s see what happens in Chicago and Berlin. If it was primarily tech that did it, we should see the record fall again.
- vessenes 5mo agoDon’t forget Yomif Kejelcha who finished in 1:59:41, a world record up until 11 seconds prior. Amazing.
- ronbenton 5mo agoImagine having the second fastest marathon time ever yet not winning the marathon you ran it in
- m463 5mo agoNobody ever remembers who was in 2nd. sigh.
- tim333 5mo agoI think Kejelcha will be back.
- twobitshifter 5mo agoApparently 3 people broke the record in the same race!
- curt15 5mo ago> Don’t forget Yomif Kejelcha who finished in 1:59:41, a world record up until 11 seconds prior. Amazing. In his marathon debut too.
- giarc 5mo agoI read that as well... how could it be his first marathon? Or is it his first "big" marathon?
- wging 5mo agoIt's his first marathon ever, but he's a very experienced runner. It would be hard to find a better prospect for a good first marathon. He's a multiple (former) world record holder and medalist at shorter distances from the mile up to half marathon. His half marathon is still 2nd all time. I wouldn't have predicted this out of nowhere, but if you told me a marathon debut went this well and asked me to guess whose it was, I like to think I'd have come up with Kejelcha in my top few picks. That said, great 5000/10000 athletes don't always have great marathon careers. An example from this race is the world record holder at both those distances, Joshua Cheptegei. He's run several marathons but none spectacular by his standards. He was in this race too but 7 minutes back.
- dwayne_dibley 5mo ago> His half marathon is still 2nd all time. Rough that his Marathon time is also 2nd!
- clutter55561 5mo ago~~A car going as fast as him would have gotten a speeding ticket in the residential areas of Wales. Crazy.~~ Edit: I was thinking in km/h and mixed it up. Sorry.
- edo_cat 5mo agoSpeed limit is 20mph right? He ran 26.1 miles in 2 hours so average speed is 13 mph
- adzm 5mo agoLooking this up, fastest human is still Usain Bolt at 27.78mph (at one point in a 100 meter dash)
- clutter55561 5mo agoDamn was thinking km/h. Thanks for the correction.
- sowbug 5mo agoYou actually can get a ticket for driving 13 in a 25, at least in the US, so you're not entirely incorrect.
- clutter55561 5mo agoFair enough. My kids are learning to drive and “how fast should I go” is a constant topic in my family right now. Just yesterday I saw a learner driving at what seemed 10 mph in a 40 mph road, creating a massive queue.
- not_a_bot_4sho 5mo agoAmazing to me that I'll never get my *half* marathon time close to his full marathon time.
- nradov 5mo agoA 1:59 half marathon time is achievable for pretty much anyone who doesn't have a serious physical disability and is willing to put in the necessary training. I've done it a few times and have no particular talent for running.
- PaulDavisThe1st 5mo agoThat's a 9m10sec per mile for 2 hours. While I'd agree that there are millions or even billions of people who could train to do that, I think it's wrong to suggest that "pretty much anyone" could do that.
- pollymarket 5mo agoMy predicted half time is under 2 hours and I was sedentary for years before starting to run 9 months ago, and I'm 40 years old. Endurance sports are quite accessible and don't require that much time, effort, or talent to get way better than the vast majority of people, it's just consistency.
- PaulDavisThe1st 5mo agoI've been an endurance athlete most of my life, running 100 miles at 17, a 5:30 mile at 50, and lots of other stuff in between. I know that a 9min/mile pace is "easily achievable" by many folks, which is why I noted that millions or billions of people could do this. Nevertheless, I think it is really important to not overstate how achievable this is - there are many more people who could not do this than could, I think. FWIW, that now includes me, as a 62 year old. I can hit 6:30 pace for 400m, but find it almost impossible to get under 10:0x for a mile. And that's even after 6 months of training for a 50 mile trail race.
- freediver 5mo agoIncredible result! (on the day I did my own 5K pb) This is a nice video of the last 10 mins of the historic marathon race finish https://www.youtube.com/watch?v=1voTDQQQf5g https://www.youtube.com/watch?v=1voTDQQQf5g
- bongripper 5mo ago[dead]
- cowthulhu 5mo agoWow, that’s ~13 mph, basically a full-on sprint for a mere mortal. Absolutely insane.
- soupfordummies 5mo agoYeah I can barely even ride my bike that fast much less keep that pace for two hours.
- willsmith72 5mo agoYou must be crawling on your bike I'd love to see that
- Maxion 5mo agoThat's just a mean comment
- Cthulhu_ 5mo agoI'm not a runner at all, but people say that they can do that for like a minute, maybe two at best... and these guys did it for two hours straight.
- PaulDavisThe1st 5mo agoThe fastest marathoners are moving at 4m30sec per mile or faster. Very few mere mortals could run that fast for even 100m.
- jonplackett 5mo agoSometimes they have big running machines with a crash mat around them running at 2h marathon pace at running shows. I’ve o ly seen them on video - no one can keep up with it for more than 30 odd seconds. It’s INSANE they are running this fast. Also bear in mind running a single mile under 4 mins was considered impossible for a long time.
- petepete 5mo ago
- wavemode 5mo agoThat's literally running a 4:30 mile, 26 times in a row. Jesus.
- ccheever 5mo ago4:33
- almost_usual 5mo agoWhile consuming about 800 calories.
- adverbly 5mo agoWait two runners beat it in the same race? Was there perfect conditions.or something? Insane you could run 1:59:41 and not win!
- hdndjsbbs 5mo agoPacing is a big part of endurance sport. If you're in the lead you know intellectually you want to pace for sub-2 hours, but if you're watching someone beat you maybe it gives you the extra edge? It does sound like the course and the weather made it more likely to happen. And technical advances in shoe composition.
- PaulDavisThe1st 5mo agoThat's not a description of how the pacing for this race actually happened. > The leading men went through halfway in 60 minutes and 29 seconds: fast but not exceptionally so. But it turned out that Sawe was merely warming up. Between 30 and 35 kilometres, Sawe and Kejelcha ran a stunning 13:54 for 5km to see off Kiplimo. Yet, staggeringly, more was to come as the pair covered kilometres 35 to 40 in 13:42. To put this into context, that time is two seconds faster than the 5km parkrun world record, set by the Irish international Nick Griggs. It was only after a 24th mile, run in 4:12, that Kejelcha wilted. But still Sawe kept going. Astonishingly, he crossed the line having run the second half in just over 59 minutes. “Before 41 kilometres, I’m enjoying, I’m relaxed,” said Kejelcha, who had won silver over 10,000m at last year’s world championships. “My body is all great. At exactly 41 kilometres, my body stopped. I tried to push, but my legs were done. Sawe, though, powered on to set the fastest official marathon time in history. For good measure, it was also 10 seconds faster than Eliud Kipchoge’s unofficial 26.2 mile best, set in Vienna in 2019. https://www.theguardian.com/sport/2026/apr/26/sabastian-sawe-breaks-two-hour-barrier-london-marathon-world-record https://www.theguardian.com/sport/2026/apr/26/sabastian-sawe...
- brewdad 5mo agoElite marathon runners aim for a one minute negative split (Second half faster than the first). These guys pretty much nailed it.
- ternaryoperator 5mo agoAnd the only place this appears on ESPN is if you click on "Olympics," which has nothing to do with this race. Where coverage should be: on the home page.
- conductr 5mo agoIt’s certainly noteworthy and interesting but I could see how Running as sport isn’t popular enough for front page. Especially during NBA and NHL playoffs, NFL draft, and whatever else might be going on.
- brewdad 5mo agoIf this happened at Chicago, it would be front page news. Boston and NY aren’t WR eligible. Since it happened in London, place it behind soccer in the priority list.
- timerol 5mo agoThis is the most significant record in running to fall since 1954 when a sub-4 minute mile was run. I think running can be front page news once a century
- conductr 5mo agoI get it and agree, but historical significance doesn’t factor into what they put on front page or what is popular at the moment. It’s not a slow news day for sports and they don’t think their viewers care enough. I’m sure if we had their data it would show us that they wouldn’t. It’s not meant to be malicious they just don’t report on things that don’t get enough engagement. If you look at the long list of sports they cover, there’s nothing running related even mentioned. They do now have an article on it in their Olympics category as of 2 hours ago. But I feel like them not having a breaking news coverage on a Sunday in this sport is to be expected more so than your expectation of them covering it.
- nikcub 5mo agoStunning results at the top of the field. Some interesting takeaways on both fuelling and shoes. Maurten spent months working with Sawe and other runners getting their gut capacity trained so they could absorb and burn 100 carbs per hour[0][1] > The Maurten research team was embedded with Sawe’s team in Kenya for 32 days across six trips between last and this April. They were training his gut to absorb that load by mimicking race-day protocol in training. The hydrogel technology they have developed over the past 10 years now allows athletes to absorb 90–120 grams of carbs per hour without GI distress. Second is the shoes. Adidas Adizero weigh 96 grams[2] with new foam tech and new carbon plates Nike and INEOS spent millions over years to get Kipchoge to a sub-2 in artificial conditions, and now the elite end of the field are knocking that barrier out in race conditions. Unreal. Running tech and training have been revolutionized in the past few years.

- nradov 5mo agoThe leaders were burning a lot more than 100kcal per hour. I think you mean 100g of carbohydrates per hour.
- brianwawok 5mo agoNot burning, eating. They are eating 100g of carb per hour. Burning 1000+ calories.
- ekr____ 5mo agoCorrection: 100g of carbohydrate/hr. That's approximately 400 calories/hr.
- groggo 5mo agoOne gram of carbs is 4 calories., so more like 400 calories per hour. It was confusing when the running industry switched from calories to grams of carbs, but that's all anyone talks about now.
- soopypoos 5mo agoI hope there was a runner dressed as the finish line
- soopypoos 5mo agotoo soon
- dmurray 5mo agoThere's something about the London course today that made for very good running. Three athletes broke the men's world record. One athlete broke the women's world record, and three were in the all time top 5. An Irish record was also broken, likely other countries too that I'm not familiar with. Not to take anything away from the achievements. Incredible running.
- PaulDavisThe1st 5mo ago> One athlete broke the women's world record Not so. She broke a record for a female-only-pacer marathon time. The women's world record was much, much faster.
- ekr____ 5mo agoTo add some color here: It is very helpful to have someone pace you so that you can run an ideal pace without worrying about whether you are running the right speed. However, the rules require that pacers start with you [0], which means that by definition if you are running faster than anyone has ever gone before you have to run some of the race alone. However, because marathon are often mixed gender and the best male runners are significantly faster than the best female runners, it is possible for a woman to be paced from the gun to the tape by a male runner. For this reason, there are separate records for the women's marathon for women's only events. [0] This is one of the things that made Kipchoge's original sub 2 result not record-eligible.
- ungreased0675 5mo agoHaving a pacer start with you seems to defeat the purpose? I’d prefer someone fresh and full of energy to jump in halfway to carry me through the end.
- dmurray 5mo agoI stand corrected, but I don't think this changes my point at all. She broke the thing that the IAAF have gone back and forth on calling "the world record". It's the relevant record for this event - there was no more chance of her beating the man-paced record than of beating the men's record or the Le Mans lap record.
- piker 5mo agoInsane; and second place was sub-2:00 as well. Relegated to trivia questions for the next decade. It would be interesting to adjust this speed to account for the insane advancements in shoe technology over the last decade. Could it be as simple as measuring the delta in median marathon performance? Then look backwards to, say, 1996 and see what the technology-adjusted 2:00 mark is.
- nradov 5mo agoThe confounding variable is higher carbohydrate intake based on optimizing the glucose/fructose ratio and improved techniques for gut training. That happened at about the same time as the new carbon fiber shoes so it's hard to isolate how much impact the shoes had alone.
- wry_durian 5mo agoI suspect there would be larger deltas due to improvements in nutrition and fueling. As another poster has mentioned, today's runners are ingesting so many more carbs per hour than 20 or 30 years ago. And if doping trends have changed over time, that's another factor. (No clue either way, but it's a potential factor.) There's been lots of research into shoes though, so you might be able to work something out. For instance Jack Daniels (the running coach, not the beverage!) found that adding 100 grams to a running shoe increased aerobic effort by around 1%.
- canucker2016 5mo agoSecond place male runner was running his first marathon race as well. Sub-2hr marathon, beat the previous world record before Sunday, on your first try, and you don't win! Bad timing... Prize money for London Marathon 2026 - https://www.thesun.co.uk/sport/38880592/london-marathon-2026-prize-money-previous-winners/ https://www.thesun.co.uk/sport/38880592/london-marathon-2026... Looks like first place male gets US$330K. Second place will get US$180K. Divide by 2 to get the approximate hourly rate. :)
- michaelt 5mo ago> Could it be as simple as measuring the delta in median marathon performance? The popularity of running waxes and wanes - and the performance of the median runner varies with popularity. Back in the 1980s the average half marathon finishing time was 1 hour 40 minutes - whereas today it's a little above 2 hours because there are a lot more people particpating.
- Noaidi 5mo ago[flagged]
- soupfordummies 5mo agoSo if the weather was bad the accomplishment would mean more then? I don’t think this is how it works. Sports don’t happen in a vacuum.
- Noaidi 5mo agoYes. If sports does not happen in a vacuum then comparisons are unfair. If I go to the moon and break the record for long jumping should I be applauded? I thought there were scientists on here...
- gbnwl 5mo agoNever thought I'd see the day ragebait made it to HN. Yes, let's pretend doing a long jump on the moon is comparable to running a marathon at its prescheduled time at its prescheduled location. Weather is always a factor in sports that take place outside. Might as well put asterisks on all accomplishments that took place on sunny days by your logic right?
- Noaidi 5mo agoIt’s either scientific or it’s not. Don’t forget that two people actually ran under the two hour mark.
- ternaryoperator 5mo agoNot sure I understand what you mean by "scientific." If you mean exactly reproducible, then almost nothing in athletics fits that definition. Every record in baseball, football, etc. would fail that definition.
- 5mo ago
- UebVar 5mo agoThis is historic. To put this into perspective for people how to not follow running: This is about about as big as "derGrobe" beating the one-minute-mark in 4b2c.
- jonplackett 5mo agoThese were Sabastian Sawe's splits 5km - 14:14 10km - 28:35 15km - 43:10 20km - 57:21 Half - 60:29 25km - 71:41 30km - 1:26:03 35km - 1:39:57 40km - 1:53:39 Finish - 1:59:30 Yomif Kejelcha also ran sub-two, clocking 1:59:41 on his debut marathon You have to feel for Kejelcha - breaking 2h marathon and not even winning the race!
- spenjovewkwhalo 5mo agoPosted to my in-laws, who asked how: Super shoes. Most shoes have carbon plates in them now, they act as a spring, storing energy and propelling athletes forwards. Better understanding of fuelling. Most athletes are taking between 100-120g carbs (sugar) per hour. Bicarbonate of soda has also been effective. Better planning tools. Athletes look at elevation, headwind, tailwind and will plan a strategy around going harder into the hard stuff and knowing when they can back off and rest. And to be honest, probably a metric tonne of PEDs (performance enhancing drugs) - unfortunately this is very common across all sports at the top level.
- k2enemy 5mo ago> Most shoes have carbon plates in them now, they act as a spring, storing energy and propelling athletes forwards. This seems unlikely to be true, although it is repeated in every article I read about carbon plated shoes. The people that study them in a lab environment seem to disagree. See some of the papers here: https://www.wouterhoogkamer.com/science2 https://www.wouterhoogkamer.com/science2 However, I agree wholeheartedly with the overall points in your post!
- spenjovewkwhalo 5mo agoOoooh, interesting- I’ll take a read, thanks! I’m guessing like most things of this nature, you’re likely to have super-responders, responders and non-responders?
- giarc 5mo agoMaybe even placebo effect?
- sampullman 5mo agoSo you think the Vaporfly prototypes Kipchoge wore in 2018 placebo'd him into crushing the world record by 78 seconds?
- alex1138 5mo agoWHAT???? NO. WAY. That's not me being sarcastic. I never, ever thought this would happen
- Metacelsus 5mo agoIt's always interesting to see East Africans doing so well. Even with technology like advances in shoes and diet/training, genetics is still a huge factor. Also it must be an crazy feeling to be Kejelcha, the guy who came in 2nd place. It would have been a world record, except for Sawe!
- geargrinder 5mo agoIt was his first marathon, so he is probably thinking next time he will be the one to break the record.
- elchief 5mo agoNot necessarily genetic. They run a lot, at altitude, from childhood
- kyawzazaw 5mo agoi feel like over a time, it becomes encoded
- tdiff 5mo agoIs it actually allowed to suggest that some races are better than others in some areas?
- tialaramex 5mo agoKinda, sorta. There's a statistical effect here but it's crucial to remember these are outliers and so these people are extraordinary in how far from the median they are regardless of that statistical effect. It's also worth remembering that "race" is a social construct and is only somewhat correlated to genetics, whereas almost certainly any effect we're talking about here is dominated by genetics, although fun fact, Sawe's uncle is apparently a moderately famous runner and hooked him up with a trainer, so it's not like "Knowing a guy who knows a guy" didn't help and that's way less to do with genetics. The "scientific racism" of confusing "The world's fastest sprinters tend to be from this Haplogroup" with "Everybody in that Haplogroup is an Athlete and so can't do intellectual stuff" is completely insane, that's how you get "I bet this old white man from a Reality TV show will be a better executive leader than that black politician we had last time".
- codezero 5mo agoThose shoes are gonna sell like crazy now but it would be hilarious if they were to be found to have been giving an unfair advantage because of some mechanical property of the shoe.
- sergiotapia 5mo agowhat else could it possibly be if not that?
- robot_jesus 5mo agoWell, the marathon record has been broken 53 times since the early 1900s. So, there are a lot of factors at play. Better training, better nutrition, better tactics, and, yes, better shoes. The advancements in shoes have made a measurable impact, but there are lots of optimizations being worked on.
- tialaramex 5mo agoAlso population and access. In the time since the early 1900s a lot more humans exist, and more of them have the opportunity to attempt this record. Population in Africa exploded in that time and access improved significantly. If you're bloody quick and born in Birmingham (either of them) in 1900 you can probably find out about and get yourself a chance to attempt that world record, but if you're born in Kapsabet (in Kenya) in 1900 good luck, even in Nairobi I wouldn't bet on it.
- deleted 5mo ago[deleted]
- jonplackett 5mo agoThere’s info in one of the other threads about better carb intake too. But yeah at this point, “it’s the shoes, stupid” should defo be the main part of the conversation.
- DwnVoteHoneyPot 5mo ago[flagged]
- signorovitch 5mo agoFeel a bit bad for Yomif Kejelcha who also broke the 2-hour mark, with this being his first competition marathon, but managed to neither break a record nor win.
- MengerSponge 5mo agoReal "Bad Luck Brian" energy https://knowyourmeme.com/memes/bad-luck-brian https://knowyourmeme.com/memes/bad-luck-brian
- parsimo2010 5mo agoWhile that seems like a bummer, as long as he doesn't quit he'll have many more chances to set the record himself.
- darth_avocado 5mo agoWhile I know competitors want to always strive to be the best, as a completely normal human who struggles to complete a half marathon under two hours, I do not feel bad for the guy. He’s still one of the only two people to do it (outside of the very controlled run from Kipchoge). Not a feat to feel bad about at all.
- cflewis 5mo agoThe majority of people in the world cannot complete a half marathon, let alone under two hours. I was pleased to train enough that I managed under three. You're doing great!
- elchief 5mo agoKipchoge broke 2h a few years ago, but it was on a closed, low altitude track, with a fleet of rotating runners in front of him, providing wind blocking/drafting as well as pacing Amazing these guys did it in a real race with no one in front of them (at the end at least)
- readthenotes1 5mo agoA purist might want the athletes to wear the same gear as Pheidippides
- jonplackett 5mo agoA purist just wants it to be about the runner not the shoe.
- _carbyau_ 5mo agoPurism is extremism about a thing. Pick a thing, be purely about that thing. I used to love F1 for the tech that would filter down to my car in ten years time, but that is not a thing anymore. I for one love the advances in technology in something as supposedly simple as a shoe. And maybe I'll get to use it on a hike in a few years.
- teruakohatu 5mo ago> I for one love the advances in technology in something as supposedly simple as a shoe. And maybe I'll get to use it on a hike in a few years. These shoes are practically disposable. They trade longevity for noticeable gains in performance. Even the tier below don’t last very long. This is not tech that is going to filter down to your hiking boots.
- _carbyau_ 5mo agoFair enough, I obviously haven't looked into it. But the initial tech on an F1 car was not made for 200k miles either. Even if the full tech stack to make it all work - material science, physical layout and construction - doesn't transfer, maybe some bit of it will. My point being though, unlike some purists, I like the technology race. It is much better than having a brand war simply on the basis of brand loyalty.
- mayneack 5mo agoThere's a whole industry of hiking gear that has been steadily trading weight for durability. I only hike in running shoes (altras) which only last me 400 or so miles. It's way less durable than my old boots. I doubt this sort of thing will translate, but I wouldn't put it past hikers to opt for something less durable to shave a few grams.
- rhplus 5mo agoIs there also something beneficial about the shirt he wore? It has a unique embossed pattern on the chest. Is it just a nice design or does it also provide aerodynamic or heat wicking advantage? https://news.adidas.com/sabastian-sawe---london-marathon/a/05a7a778-ec7a-4a41-94f6-a9b29e0e1eb7 https://news.adidas.com/sabastian-sawe---london-marathon/a/0...
- double0jimb0 5mo agoGood eye! Almost like an inverted golf ball. If I remember correctly from undergrad aero, purpose of dimples on golf ball is to detach/disrupt more of any laminar flow earlier as air passes around the ball, which decreases drag. Golf balls travel way faster than a runner, but possibly still has some minor effect?
- huflungdung 5mo ago[dead]
- cevn 5mo agoI can sort of visualize an aero improvement. If wind hits you flat on it goes all around and right against you, and it can bump into itself and then back on you since it's almost directionless. However if you have 'needles' coming out it gives the wind a 'direction' other than straight at you, lessening the pressure against your front.
- bbcc90 5mo agoI'm a runner, and it's a bit sad that distance running is not longer purely about the runner. Based on the quote below, next thing we will see is a "constructors championship" similar to F1 for winning shoe constructor in the 'major' marathons :-(. " This dominance continued in 2024, with adidas athletes wearing Adizero models winning six out of 12 World Major Marathons – more than any other brand." and yes, of course i race in super shoes :-).
- nerder92 5mo agoIt was never about the runner, it has always been about technology and innovation. Shoes tech is just one of them. Better nutrition, novel training techniques, better air quality etc. Of course innovation in shoes will have a bigger marginal impact (because physics).
- bbcc90 5mo agoFor sure but most of that innovation pre-super shoes was optimizing the runner, not the shoes
- foxglacier 5mo agoOf course it's also about the runner, that's why the Kenyan models dominate with their biological innovation.
- jampekka 5mo agoCan't help but think that the wins and records done barefoot and without refreshments in the 1960s are still a bit more about the runner than running with essentially spring loaded shoes, lab-optimized nutrition gels, computer optimized pacing strategies and multisensor real-time measurement devices. It's also somewhat ironic for a race supposedly modeling a messenger running the distance in an emergency situation.
- Ekaros 5mo agoAlso makes wonder question did the messenger participate in hard cardio training before. Meaning the fighting. Or do some messengering before.
- mellosouls 5mo agoGreat achievement. Worth remembering also the previous world record holder, Kelvin Kiptum who sadly died at 24 in a car accident a couple of years ago. https://en.wikipedia.org/wiki/Kelvin_Kiptum https://en.wikipedia.org/wiki/Kelvin_Kiptum
