Tor des Géants 330 km: Two Vietnamese Finishers in 138 Hours and the Arithmetic of the 150-Hour Cut-Off

When Lê Thị Hằng touched the finish line at Courmayeur, the Tor des Géants organizers' clock had run past 138 hours and 40 minutes. Not far away, at a different point in the same race, Lưu Đức Toản stopped the clock at 137 hours and 50 minutes. I sat in front of a screen in Osaka, opened the results sheet, and placed the two Vietnamese times beside the two winners' times: 65 hours 55 minutes for Jia Ju Zhao in the men's race, 67 hours 10 minutes for Katharina Hartmuth in the women's race. The division yields just over 2.1 times. On a 330 km course with more than 24,000 meters of cumulative climbing, that doubling shapes the entire way the result should be read.

I have followed mountain races long enough to know that a finisher's medal at Tor des Géants is not the same as a medal on a flat road course. From my years working with running data, I learned that admiration must be placed in the right spot. Finishing Tor des Géants is an achievement of endurance; it is not a top-of-field performance. Both things can be true at once. Separating them does not diminish the achievement — on the contrary, it shows where its true value lies.

The Course and the Rules

Tor des Géants is a single-stage, non-stop mountain race held in the Aosta Valley, in northwestern Italy. It was first organized in 2026, and within the ultra-trail world it sits among the races considered the harshest on the planet. The main distance is 330 km, run across the high passes of the Alps, with cumulative elevation gain exceeding 24,000 meters and more than 20 passes located above 2,000 meters. This year's race window fell between September 13 and September 19.

Three features define this race, and also how its results are read.

The first is the single-stage, non-stop format. There are no fixed daily stages, no mandated rest hours. Athletes manage their own running, eating, sleeping, and recovery throughout the journey. That turns the race from a multi-day event into a continuous survival test, where finishing itself carries value.

The second is the resupply system. Seven large support stations are placed roughly 50 km apart, providing food, water, and medical support. These stations become strategic landmarks: athletes divide the race into 50 km segments, and every stop is a delicate decision between recovery and lost time.

The third is the time boundary. The cut-off is 150 hours. Beyond that mark, an athlete is eliminated, wherever they are on the course.

With those three features, Tor des Géants does not select its participants at the entry gate. It selects finishers at the final line. And the race's completion rate is only about 60%. In other words, roughly 40% of those who stand at the start will never touch the finish.

A Memory of Data Shattering

There is a memory I still carry whenever I read extreme results like this. In 2026, while still a school student, I recorded every match of the Japanese national team at the World Cup in Russia in meticulous detail. In the match against Belgium, Japan touched the ball inside the opponent's box only 7 times against Belgium's 21, despite holding 55% possession. I wrote an analysis based on the data and argued that pushing the line high in the closing minutes was a mistake. The article was fiercely criticized. That night in Russia in 2026, I watched data shatter before my eyes.

The lesson I drew was not to abandon data, but to understand its limits. A number can be technically correct yet placed in the wrong context. The Tor des Géants result of the two Vietnamese runners is such a case. Read only the headline, and one sees a heroic story. Read the results sheet, and one sees a different story, more complex and more honest.

The Arithmetic of Time and the Four Tiers of a Race

On the results sheet, the gap between the winner and the two Vietnamese runners is nearly 70 hours. To understand this gap, it must be placed within the structure of the race itself.

Tor des Géants does not operate like a track event with standard rankings. It has no qualification-standard entry, no world ranking points, no national team. Entry is granted through a points-accumulation system at prior ultra-trail races, plus a lottery component. As a result, the field's ability range is very wide: from the world's top professionals to hardened amateurs.

At the front, Jia Ju Zhao and Katharina Hartmuth are genuine ultra-trail specialists. They finished in about 66 to 67 hours, meaning they ran continuously at an astonishing average pace across mountain terrain. In the mid and back groups, Lê Thị Hằng and Lưu Đức Toản finished in about 138 hours, double the winner's time.

This doubling is normal at Tor des Géants. The winners are professional runners, earning a living from the sport and devoting all their time to optimizing every detail. The two Vietnamese are high-level amateur runners. The difference in resources and training time explains much of the gap.

I usually picture the results of an ultra-trail race in four tiers. The championship tier, where global specialists contest the title. The sub-80-hour tier, very strong runners. The mid and back tiers, where most finishers sit. And the DNF zone, where roughly 40% of participants stop.

Lê Thị Hằng and Lưu Đức Toản sit in the mid and back tiers. That does not diminish the value of the achievement, but it positions it precisely. They are strong amateur runners who conquered a race that four in ten people cannot finish.

The Load of Altitude

One of the most common mistakes when reading ultra-trail results is comparing times directly with flat road races. Here, finishing time is governed by terrain and altitude far more than by pure speed.

What does more than 24,000 meters of cumulative climbing mean? It is equivalent to climbing Mount Everest from sea level nearly three times, or running along a vertical slope 24 km long. But unlike climbing Everest, athletes must climb and descend on their own, again and again, over many days, with a backpack.

More than 20 passes above 2,000 meters create another challenge: diurnal temperature swings. During the day, the sun at high altitude can be hot. At night, temperatures at 2,000 meters and above can drop below freezing. The body must constantly adjust, and each adjustment costs energy.

For this reason, the Vietnamese runners' 138 hours carries a different meaning from 138 hours on a flat road. It is a measure of raw endurance, not of speed. Altitude and terrain inflate finishing time substantially, and any comparison that ignores these two variables is meaningless.

An Eleven-Hour Safety Margin

The 150-hour cut-off and the 138-hour result create a margin of about 11 to 12 hours. This is a safe but not comfortable buffer zone.

Over more than five and a half days of continuous running, a small incident can quickly consume the buffer. A minor injury, a night slept too long at a support station, a stomach issue making eating difficult — any of these can add hours. On this course, hours are something runners cannot spare.

The two Vietnamese finished without ever being in time danger, but they also had no margin for a major incident. The 138-hour result sits in the safe zone, but it is a safe zone created by discipline, not by luck.

The Real Filter Is at the Finish Line

The most objective indicator of Tor des Géants' difficulty is its completion rate of about 60%. For every ten starters, four will drop out. In a race where finishing is itself an achievement, the two Vietnamese are in the successful minority.

The race's real filter is at the finish line, not at the registration gate. There is no performance standard to enter, but there is a harsh standard to complete. And that standard cannot be simulated in advance. Runners only know whether they can pass it after spending five and a half days in the mountains. For a race that filters people at the finish rather than the gate, finishing in about 138 hours is a result above the median of expectation.

The Two Runners' Profiles

This result is not an anomalous leap. Both athletes had prior long-distance foundations. Lê Thị Hằng, from Vũng Tàu, had completed Prenn Trail 250 km, Son La Ultra Trail 100 km, and VMM 100 km. Lưu Đức Toản had run UTMB, Mantra 116 km, ULJU Trail 9 Peaks 100 km, and Mt Fuji 100 km.

Looking at this list, one can see a deliberate evolution path. Both started from the 100 km distance, accumulated experience across mountain races, and only then stepped up to 330 km. This is the correct approach in ultra-trail running, where increasing distance too quickly often leads to failure or injury.

Notably, Lưu Đức Toản had previously completed UTMB, another prestigious ultra-trail race. He described Tor des Géants as many times harder than UTMB. This is a technical judgment from an insider's perspective, and his prior UTMB finish gives it weight. The long-distance records of both show that the 330 km result is the consequence of a foundation built over years, not a single stroke of luck.

Another notable detail is the gap between the two Vietnamese. Lê Thị Hằng finished in 138 hours 40 minutes, Lưu Đức Toản in 137 hours 50 minutes. The difference is only about 50 minutes over 330 km. In ultra-trail running, such a narrow gap between two athletes often suggests a mutual support strategy, or at least an astonishingly similar pacing rhythm. This is a hypothesis, not a conclusion, because split data was not published.

The Third Runner and the DNF Zone

Within the Vietnamese group, there was a third person living in France. This person did not finish the race. The detail matters for two reasons. It confirms that the DNF zone is not an abstract concept — it was present within the same small Vietnamese group. And it shows that living near the Alps does not automatically mean being ready for the race. Geographic proximity differs from physiological adaptation and professional preparation.

The presence of a drop-out within the same group reminds us that finishing Tor des Géants is never guaranteed, even for someone who has prepared.

The Life-Safety Dimension

An aspect often overlooked in coverage of ultra-trail is the life-safety dimension. Tor des Géants has a notable precedent: in 2026, an athlete named Yang Yuan died after slipping and hitting his head on rock. Lưu Đức Toản described narrow paths along cliff faces, without safety ropes. This is a direct account from an insider, and it matches the 2026 precedent.

In many sports, risk is managed by safety measures; here, risk is managed largely by the athlete's own responsibility. For someone who works with data, this is the hardest kind of variable to model. No number measures the chance of a slip. But the existence of a fatality precedent shows that the risk is real, not hypothetical.

From the perspective of someone living in Japan and following international sport, I notice that mountain-running culture has a particular characteristic. At races like this, there are no grandstands, no cheering, no crowd witnessing most of the course. An empty stadium, yet the numbers are still full of noise. Here, the noise does not come from spectators but from unmeasurable variables: weather, health, mindset, and the randomness of terrain.

Which Frame Honors This Achievement Better

There is something most coverage of this result will not say, and I think it needs to be said.

The story is told through the frame of conquering one of the world's harshest races. That frame is factually accurate. But it inadvertently creates a halo of competitive level. When an article places the two Vietnamese beside the winners, and quotes dramatic statements about the difficulty, readers easily imagine an evenly matched contest. In reality, the gap is double.

The coverage does not state the specific finishing positions of the two Vietnamese. This may be a deliberate choice to focus on the completion frame rather than the competition frame. I understand the reason for that choice. But omitting positions and split data prevents readers from judging the quality of the run for themselves.

The counter-intuitive point here is that emphasizing the completion aspect is actually the most honest way to honor this achievement. Its true value lies in the 60% completion rate, not in a contest with the front. If we try to turn it into a competition story, we inadvertently weaken it. The value of this result does not come from how it compares to the winner, but from the fact that four in ten people could not do what the two Vietnamese did.

There is a second counter-intuitive point, related to safety. While the media focuses on the glory of finishing, the life-risk dimension deserves more mention. A race with a fatality precedent and cliff sections without safety ropes calls for more responsible coverage than mere praise of a heroic spirit. This does not diminish the two Vietnamese runners' achievement. On the contrary, it highlights the preparation and discipline required to pass through such a course without incident.

Where This Result Travels

At the industry level, the two Vietnamese runners' result has a modest but clear effect. Tor des Géants sits outside the ecosystem of broadcast rights and large prize money. It belongs to no Olympic structure, no world championship system, no athletics Diamond League. Its authority comes from difficulty and prestige, not from administrative tiers.

So the result's global commercial impact is near zero. But at the domestic level, the impact is real. This story feeds a growing long-distance running market in Vietnam. The list of races the two athletes have run — Prenn Trail 250 km, Son La Ultra Trail, VMM, ULJU, Mt Fuji — shows that a domestic and regional race ecosystem has matured enough to nurture runners reaching out internationally.

For mountain-running gear sellers, this is marketing proof. For domestic race organizers, it is a milestone to promote. For young runners, it is an aspirational signal. These effects are small, but they accumulate over time.

Signals for the Next Cycle

This result sits at the intersection of two larger trends. The first is the maturation of Vietnam's ultra-trail community. The existence of races like Prenn Trail 250 km, Son La Ultra Trail, and VMM shows that a domestic race ecosystem has matured enough to nurture athletes reaching out internationally. The second is Asia's expansion into the front of ultra-trail, marked by Jia Ju Zhao's win in the men's race.

What is worth tracking is not a single result, but repetition. If in the coming years Vietnamese runners consistently finish international ultra-trail races, especially in the top third, then this 330 km result will be seen as a starting milestone, not a one-off phenomenon. Conversely, if this is an isolated case, it retains its value as a personal achievement, but says little about a trend.

Data does not create stories; it strips bare the stories of others. The real story here is one of endurance built over years, on a course where finishing is already a victory.

Every probability hides a shock — I only make sure it does not repeat. At Tor des Géants, that shock has a name, and it comes from 2026. Mentioning it is not to blur the two Vietnamese runners' achievement, but to make the next runners understand the course they are about to enter.
