We answer all of your questions about this hellacious footsport event

If you’re starting to dip your toes into the crazy sport of ultrarunning, a couple of things will happen. First, you’re going to need several pairs of the best trail running shoes in rotation at any given time to put up with all those miles pounding rocky trails, and second, it won’t be long before you hear mention of the UTMB. 

In fact, I recently attended the Arc’teryx Alpine Academy in Chamonix which holds a number of trail running clinics, and over the course of four days it was rare to have a conversation where the UTMB didn’t come up. Other participants in the academy wanted to know if our mountain guides had run it, how many times and whether they liked it (they don’t, considering it a tourist event) and mountain guides were keen to complain about how busy it made their favorite running trail.

But what is the UTMB exactly? Is it the ultimate goal for all trail runners? Why is it so hard? Here, we answer all of your questions about this hellacious footsport event.

What is the UTMB race?

UTMB stands for Ultra-Trail du Mont Blanc and is considered one of the world's premier trail ultra marathons. This demanding annual event follows the route of the Tour du Mont Blanc, a classic long distance hiking trail which circles the Mont Blanc Massif over 106 miles and passes through France, Switzerland and Italy. The UTMB begins and ends in Chamonix and is regarded as one of the most difficult races in the world. 

The race takes place on the last weekend of August or first weekend of September and is today the ultimate in a series of events that take place around the world. Runners from all over the world aspire to compete in the UTMB. In the first year of the race, there were 700 participants, but these days, participation is capped at around 2,300 runners and other events have been created to allow for more participation. 

The maximum cutoff for the race is 46.5 hours. In 2022, Kilian Jornet became the first to complete the UTMB in less than 20 hours (check out his race data to find out how he managed it) but most mere mortals can expect to have to run for two days and two nights to complete the race. Better bring some running gels then! 

How does the UTMB race work?

Due to the event’s extreme popularity, you need to qualify to run the UTMB. That involves accumulating points through qualifying trail races over a two-year period. Qualifying races take place all over the world, from elsewhere in the Alps to Snowdonia, California, Mexico, Hong Kong and Australia. So if you’re serious about participating, you’ll have lots of time to train.

For each event you participate in and complete you’ll receive one running stone, which you can then enter into the lottery to be selected. You can enter the lottery at the UTMB website. 

Why is UTMB so hard?

Besides the fact that at over 100 miles, it’s very long, competitors in the UTMB are also looking at 32,940 feet of elevation gain. In comparison, over roughly the same distance you could run the Leadville 100 in Colorado and gain only 11,000 feet (though at much higher altitude) or the West Highland Way in Scotland where you’d gain 10,300 feet.

The highest point of the route is 8,743 feet, which you’ll reach twice, in both Switzerland and France. That’s not extremely high altitude and it’s unlikely you’d experience altitude sickness at that height, but you’ll definitely notice shortness of breath and more challenging conditions, especially if you’re not already used to this altitude.

What you can also expect is more extreme conditions that come with trail running in the Alps. The altitude combined with the season means that the days might be swelteringly hot, while the temperatures at night could drop down around freezing at night. 

How much does it cost to enter UTMB?

In 2023, the UTMB itself cost €335 to enter, plus administration fees. Of course, you’ll also have to pay registration fees for your qualifying events too. Your race will also include the cost of traveling to and from Chamonix, and accommodation while you’re there, but on the plus side the aid stations will be on hand to feed you during the race so you can save a little on those pricey Chamonix restaurants.

How many people have died in UTMB?

Sadly, deaths do occur in ultrarunning events and it’s perhaps more remarkable that for 17 years, no fatalities occurred during the UTMB, which not only places runners’ under extreme physical stress but entails a lot of night running. There have now been two deaths of runners in the UTMB, occurring in 2021 and 2022, both as the result of falls.

Do people sleep during UTMB?

Some runners somehow manage to do the UTMB without sleeping at all while others do sleep, but they’re not carrying a bivy sack and grabbing eight hours if that’s what you’re wondering. Sleeping during the UTMB looks like cat napping, and according to a 2015 study of 17 UTMB runners, the average time spent resting was between 12 and 17 minutes in total, and hallucinations were a common complaint, understandably.

Can you walk the UTMB?

Can you walk the UTMB? Well, yeah you could. Since the race is 106 miles and you have 46.5 hours to complete it, you technically could walk at a 2.3 mile per hour pace without any breaks and make the cutoff. Obviously though, you could just walk it at a time when the race isn't going on, save yourself €335 and enjoy far fewer people on the trail.

In all seriousness though, if you don’t already know, ultrarunning is actually hiking, and you’re not going to be running at the same pace you do on the tarmac back home. Even Jornet ran at an adjusted pace of around five miles per hour which isn’t exactly turbo speed (though it is if you maintain that for 20 hours). You’ll most likely walk the uphills and slow down or walk for rest periods, making up time on the downhills. And sorry, there aren’t many flats to speak of.

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.

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

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.

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.
