Le Thi Hang – Luu Duc Toan: 330 Non-Stop Kilometres in Aosta and the Finish Line of a 60% Minority

On the narrow path along the cliffside in Aosta, there are no safety ropes. Luu Duc Toan described this after finishing, and that detail made me pause longer than his 137 hours and 50 minutes. On one side, a rock wall; on the other, empty space. Over a 330 km course, every step depends entirely on the runner.

Not far away, Le Thi Hang, a woman from Vung Tau, had also just finished, in 138 hours and 40 minutes. Two Vietnamese runners, one man and one woman, separated by fifty minutes over a journey lasting nearly six days and nights. Over such a distance, that gap is so thin it almost ceases to exist.

I have covered many ultra trail races in East Africa and Europe during my years writing biographies of female athletes. Every time I read Tor des Géants results, I have to remind myself that this is an endurance race, not a speed race. And this time, seeing two Vietnamese names appear side by side on the results sheet, I realised something needed to be told more carefully than a short news line about national pride.

Tor des Géants: 330 km without stages

Tor des Géants, literally the "Tower of the Giants", takes place in the Aosta Valley in northern Italy and was first held in 2026. The main distance is 330 km, run in one go, without fixed stages. This is the fundamental difference from most other mountain races: there are no mandatory stops and no organiser-imposed rest hours. Athletes manage their own running time, sleep time and eating time. The race continues until they cross the finish line or are eliminated.

In running circles, the term "ultra trail" refers to off-road races far beyond marathon distance, usually in mountain terrain with large cumulative elevation gain and a requirement for self-navigation. It differs fundamentally from road marathons and even more from track events. In a road marathon, speed is measured. In an ultra trail, endurance is measured.

The total cumulative elevation gain of the Tor des Géants course exceeds 24,000 metres. More than twenty passes sit above 2,000 metres above sea level. The cut-off time to finish is 150 hours. In practice, only around 60% of starters complete the race. Four out of ten drop out, even though all of them have passed the qualification process to reach the start line.

In 2026, the race recorded a fatality: the runner Yang Yuan fell, suffered a head injury and did not survive. This detail is not an anecdote to embellish the race's difficulty. It is part of the race's nature. When Toan spoke of narrow cliffside paths without safety ropes, he was describing the very mechanism that once took a life on the same course.

The Aosta Valley sits at the foot of the Alps, bordering France and Switzerland. It is a deeply fragmented landscape, with narrow valleys and successive mountain passes. Autumn here brings large day-to-night temperature swings. Daytime sun can make a runner sweat on a pass, while at night temperatures drop to levels that cause hypothermia if equipment is insufficient. Tor des Géants is held in mid-September, when the weather has turned cold but snow has not yet covered the high passes.

Race structure: seven stations and 50 km blocks

At Tor des Géants there are seven large support stations, spaced roughly 50 km apart. Between these stations, runners must fend for themselves with the food, water and clothing they carry. That structure shapes the entire strategy: divide the race into blocks of about 50 km and survive each block one at a time.

This sounds simple but is the source of most tactical decisions. A runner must calculate calorie expenditure between two stations, average speed over steep terrain, and the time of day they will reach the next station. If they arrive at night and feel sleepy, they must choose between a short rest to regain alertness and pushing on to save time. Each such choice compounds over nearly six days, and the final outcome is 137 hours or 145 hours.

The rule of no fixed stages and no mandatory rest is the rule that shapes the entire race. It turns Tor des Géants from a multi-day race into a continuous survival test, where finishing itself carries value. There is no "make it up tomorrow". There is no "get a full night's sleep tonight". There is only the course and the clock.

The 60% completion rate and what it really means

A completion rate of around 60% is the most objective indicator for assessing the two Vietnamese runners' result. It means nearly half of all qualified entrants failed to finish. This is not the dropout rate of a mass-participation event. It is the rate of a screening process.

Against that backdrop, Le Thi Hang and Luu Duc Toan finishing is a minority outcome. They are among the 60% who overcame the course. That is a genuine achievement, verifiable and requiring no embellishment.

Both finished with a margin of 11 to 12 hours against the 150-hour limit. That safety margin is not wide. In a race where a small incident can cost hours, an 11-hour buffer is just enough not to be cut off, but not enough to be called comfortable.

The seventy-hour gap

The men's winner was Jia Ju Zhao of China, in 65:55:22. The women's winner was Katharina Hartmuth of Germany, in 67:10:09. The two Vietnamese runners finished after more than 137 hours.

A gap of nearly seventy hours between the winning group and the Vietnamese pair places them in the mid-to-back finishing cohort, not the title-contending group. That gap is equivalent to the winners running nearly twice as fast. Yet at the same time, finishing a race with a roughly 60% completion rate is a minority outcome. This is an achievement of endurance, not of speed.

The difference in class lies here: Jia Ju Zhao and Katharina Hartmuth are professional ultra runners who make a living from mountain running. They are the elite of the discipline, able to devote all their time to training and recovery. The Vietnamese pair are high-level amateurs, self-funded in finance and logistics, balancing running with everyday life. These two groups do not compete within the same frame of reference, even though they run the same course.

What is notable is Jia Ju Zhao's victory. A Chinese runner winning Tor des Géants signals that Asia is moving into the top tier of world ultra trail, a field that European and North American athletes have dominated for decades. Vietnam's appearance on the results sheet should be read as part of that expansion wave.

The profiles of the two Vietnamese runners

Le Thi Hang comes from Vung Tau. Her published race record includes Prenn Trail 250 km, Son La Ultra Trail 100 km and VMM 100 km, the Vietnam Mountain Marathon. Luu Duc Toan's record includes UTMB, the Ultra-Trail du Mont-Blanc, Mantra 116 km, ULJU Trail 9 Peaks 100 km and Mt Fuji 100 km.

Reading this sequence of races, I see a deliberately constructed path. Both started at 100 km distances, moved up to 250 km, and only then stepped into the 330 km non-stop distance. This is not an impulsive decision. It is a multi-year accumulation, with each step placed deliberately.

Toan has completed the UTMB 100 km, one of the most prestigious ultra trail races on the planet. Asked about Tor des Géants, he said it is many times harder and more challenging. That assessment is subjective, but it is credible because the speaker has run UTMB. Someone who has conquered Mont-Blanc yet still needs the phrase "many times" to describe the gap between the two races is a signal worth listening to.

The two Vietnamese runners have no disclosed personal coach or support team. They operate according to the common model of the amateur ultra trail scene: building their own training plans, paying their own costs, handling their own logistics. No national team, no federation training programme stands behind this result.

Three Vietnamese runners entered this year's race. One, based in France, did not finish. This detail matters, because it reminds us that finishing is not a given even for someone used to living near the Alps. Geographic proximity does not substitute for altitude and cold adaptation.

There is no information on the ages of the two runners, no split data by station, no injury history. I therefore cannot make a quantitative assessment of their physical foundations. I can only say they are veteran ultra runners, and a 330 km result sits within the plausible trajectory of people who have already run 250 km.

The woman and the fifty-minute gap

I write biographies of female athletes, so the first thing I look for when reading Tor des Géants results is Le Thi Hang's performance. And what made me pause was the gap between her and her male compatriot.

Over a 330 km course, Hang finished fifty minutes behind Toan. Fifty minutes, across nearly six days and nights of continuous running, is about 0.6% of total time. At shorter distances, the gender gap is usually far more pronounced. Here, it is almost erased.

I do not have data on the entire women's field for direct comparison, so I cannot say where Hang placed among the women. But the gap between her and her male compatriot, who has UTMB on his record, is an indicator of relative depth on the women's side within the Vietnamese group.

On her feet, I saw a generation that has never been named.

In Vietnam's ultra trail scene, the number of female runners competing at distances above 100 km remains small. Every woman who appears at 330 km is rewriting a limit no one had previously touched. Hang does not need a title to establish that. Her presence in Aosta, and her finish within the 150-hour limit, is already a statement.

Another possibility should be placed on the table: given how small the time gap between the two is, it is quite possible they ran together, or shared a common support strategy for much of the course. I have no evidence for this, and it is only speculation. But if true, it says something interesting about how Vietnamese runners organise a long journey abroad, carrying both a companion and a resupply plan to another continent.

What I want to emphasise is that the fifty-minute gap should not be read as a direct comparison of ability between men and women. It should be read as a sign of the depth of Vietnam's women's group at ultra-long distances. A woman able to keep pace with a man who has run UTMB over 330 km is a fact worth recording, regardless of final placing.

A counter-intuitive angle: "conquering" and actual position

Domestic media covered this result with a familiar narrative frame: Vietnamese runners conquering one of the harshest races on the planet. That frame is factually accurate. Completing a race with a 40% dropout rate is a real achievement.

But there is a gap in how it is told.

The report does not state the two runners' placings. Nor does it publish split data for readers to assess pacing quality. This omission can unintentionally create a competitive halo larger than reality: the reader places the two Vietnamese names beside the winners' names and assumes the gap is small. In fact, that gap is nearly seventy hours.

This is a completion achievement, not a title-contending achievement. The blurring is not the runners' fault, but the fault of how the story is framed. A mature sporting scene needs to distinguish the two.

At the same time, the opposite reaction must be avoided, namely belittling the result simply because it is not at the front. The 60% completion rate is not a decorative detail. It turns finishing into a substantive accomplishment. A course does not need a grandstand to know who belongs to it.

The second blind spot concerns the training environment. Both runners come from a tropical country with no 2,000-metre passes and no cold nights below ten degrees. Preparing for a race like Tor des Géants requires altitude and cold adaptation that the report never mentions. If they had no high-mountain training camp before the race, part of the extra time relative to the leaders may come from there, not only from baseline speed.

Data gaps

An honest analysis must state clearly what it does not know. With this result, much has not been published.

There are no ages for the two runners, so they cannot be placed on a career curve. There is no split data by station, so pacing quality cannot be assessed, meaning whether they ran evenly or fell apart in the second half. There is no injury history, so nothing can be said about long-term physical foundations. There is no sponsorship information, so it cannot be determined whether they are professional or self-funded amateurs.

The absence of split data is the most serious gap, because it reduces all tactical judgement to the qualitative level. We know they finished, but not how they finished.

In ultra trail, doping controls are also less stringent than in track or road athletics. The report does not address any aspect of doping testing or entry conditions. Nothing here allows speculation in either direction, whether toward compliance or suspicion.

A risk map for a life-and-death race

When writing about ultra trail, I always ask about risk before asking about performance. At Tor des Géants, risk is not a side detail.

Toan described narrow cliffside paths without safety ropes. The accident mechanism has already occurred: a runner fell, suffered a head injury, and died in 2026. This is low-probability but catastrophic in impact.

Alongside that is altitude risk. More than twenty passes above 2,000 metres create conditions for altitude sickness and related complications. Thermal risk is no less serious: the difference between daytime sun and high-mountain night cold can cause hypothermia, especially during night running. Seven aid stations 50 km apart are the only anchor points, and that spacing is far enough for a small incident to become large.

The 60% completion rate is the most objective risk indicator. Four out of ten do not finish. That the two Vietnamese runners are among the finishers, with an 11-to-12-hour margin against the 150-hour limit, shows they managed risk effectively, but also shows they had little room to spare. A single unusually long stop, a minor injury, could push them toward the limit.

A safety margin of 11 to 12 hours against a 150-hour limit is just enough, not comfortable. In a race where one incident can cost hours, that margin is thinner than it appears.

The third Vietnamese runner dropping out is living proof that the risk is real, within the same starting group. He lives in France, near the Alps, yet still could not finish. That shows geographic proximity does not equal preparation.

The Asian story and Vietnam's position

Jia Ju Zhao's victory in the men's race deserves serious attention. Ultra trail has long been seen as a playground for European and North American runners, who enjoy advantages in training terrain and mountain-running culture. A Chinese runner winning one of the harshest races on the planet is a sign that structure is changing.

Vietnam sits at the edge of that wave, but it has appeared. The presence of two Vietnamese runners on the results sheet is a participation milestone, not yet a threat at the front. This needs to be stated clearly to avoid confusing two different levels of achievement.

Looking at the two runners' domestic records, Vietnam already has a relatively dense mountain-running ecosystem. Races such as VMM, Prenn Trail and Son La Ultra Trail show a calendar strong enough to feed athletes toward international events. This is an important foundation, because without domestic races there is no path onto the international stage.

The transmission traces of a result

From a market perspective, this result sends signals in several directions with different intensities.

The first direction is domestic culture and inspiration. Vietnam has a fast-growing mountain-running market, with races such as VMM, Prenn Trail and Son La Ultra Trail in the two runners' own records. An international result like Tor des Géants acts as validation for the domestic race ecosystem. It tells beginners that the path from a domestic 100 km race to a 330 km race in Italy is a real one.

The second direction is sports tourism. The Aosta Valley is positioned as a bucket-list challenge for Asia's mountain-running community. Every result like this thickens that destination marketing.

The third direction is equipment and gear. Backpack, trail shoe and headlamp brands gain another story to tell in the Vietnamese market. This is a small but real effect, lasting over the medium term.

At global scale, the impact is close to zero. Tor des Géants sits outside the Olympic system and outside the major world championships with large prize money. It does not generate significant broadcast revenue. Its value lies in prestige within the ultra community, not in television rights.

The value of an athlete lies in the fates that result changes, not in a placing on a scoreboard. For Hang, a woman from Vung Tau finishing in Aosta, the fate changed may be how a young girl back home sees her own limits. That is a value that cannot be measured in prize money.

It is important to distinguish two layers of impact. The first is the immediate impact on media and awareness, unfolding within days of the result. The second is the long-term impact on race infrastructure and human resources, unfolding over years. Hang and Toan's results are strong at the first layer, and have the potential to contribute to the second if tracked and recorded systematically.

What is changing

I write biographies to lift the invisible veil that men's sport has drawn over women's sport. For many years, female endurance athletes in Asia generally, and Vietnam specifically, competed in a space where almost no one recorded them. Their results existed but were not told.

What is changing, slowly but surely, is the emergence of a generation of female athletes willing to step into distances previously considered the territory of men. Le Thi Hang finished Tor des Géants in 138 hours and 40 minutes. The fifty-minute gap between her and her male teammate is a small detail, but it is the kind of detail that did not exist to be read ten years ago.

I have spent years sitting in archives, reading handwritten diaries of deceased coaches, to recover the names of female athletes never entered into official records. That work taught me that women's sporting history does not disappear because it did not exist, but because no one bothered to record it. With the Aosta result, the task is to record it fully and accurately, before it drifts into oblivion.

I do not know what Hang will do next. Perhaps she will return to Aosta. Perhaps she will move to other races. But I know what I will keep doing: following these names over the years, recording every start, every finish, and every non-finish too. Because the history of Vietnamese women's endurance sport is being written right now, and it is being written in places without grandstands.

The 330 km course in Aosta has no spectators lining the route. But it has finishers. And among this year's finishers, half are Vietnamese women.
