Two Vietnamese runners finish Tor des Géants 330 km: reading 138 hours in numbers

The clock in Courmayeur read 138 hours 40 minutes when Le Thi Hang of Vung Tau crossed the finish line of the 330 km Tor des Géants. Fifty minutes earlier, Luu Duc Toan had closed the same loop in 137 hours 50 minutes. The organisers' cut-off is 150 hours.

Put the two numbers side by side and you see a buffer of 11 to 12 hours. That is the entire safety margin on a course of 330 km, more than 24,000 metres of cumulative climbing and more than 20 passes above 2,000 metres. One rolled ankle at kilometre 280, one overslept hour at the sixth support station, one early snow squall on a col, and the 150-hour line swallows that buffer whole.

This is also the loop where, in 2026, a runner died after a fall on an unroped mountain path. Toan described it in the voice of someone who has been there: narrow trails, a rock face on one side, empty air on the other, no ropes, no netting.

I read the result in Saigon while the men's football transfer feed was boiling over a handful of names and a handful of numbers. Seventeen years ago I sat in front of a microphone with Huynh Nhu at Thong Nhat stadium. Huynh Nhu's first call smashed the house of words I had built. Since then, whenever someone achieves something the mainstream feed does not bother with, I open the data sheet first and my heart second.

That habit came from a rejected piece. In July 2026, while the newsroom poured itself into the Russia World Cup, I watched the Under-20 Women's World Cup final between Japan and Spain and became obsessed with the Japanese high press: 18.7 km of total distance per match and nine ball recoveries in the opponent's final third. My editor spiked the piece as off-topic. I posted it on my personal page and it reached one million views in 72 hours. That rejected article is now the scar I treasure most. It taught me that numbers are not for showing off, but for lighting the layer of meaning that praise misses.

A loop with no rest stops

Tor des Géants, literally the Tower of the Giants, was created in 2026 in the Aosta Valley of northern Italy. Its format makes any comparison with a road marathon meaningless: a single stage, no daily divisions, no mandatory rest hours, no collective overnight stop. Runners manage their own running, eating and sleeping across nearly a week in the mountains.

Four terms need clarifying up front. Ultra trail means off-road endurance racing far beyond marathon distance, on mountain terrain, self-navigated. Cumulative elevation gain is the total metres climbed across the whole course, not the height of one summit. COT, short for cut-off time, is the absolute deadline at which the organisers close the course, here 150 hours. DNF describes a runner who starts but does not finish.

This year's race ran inside the window of 13 to 19 September. The men's winner was Jia Ju Zhao of China in 65 hours 55 minutes 22 seconds. The women's winner was Katharina Hartmuth of Germany in 67 hours 10 minutes 09 seconds. Vietnam had three entrants: Le Thi Hang, Luu Duc Toan, and a France-based Vietnamese runner who did not finish.

The race résumés of the two finishers explain why this is not a lucky leap. Hang has run Prenn Trail 250 km, Son La Ultra Trail 100 km and VMM 100 km. Toan has run UTMB, Mantra 116 km, ULJU Trail 9 Peaks 100 km and Mt Fuji 100 km. Those names are familiar to anyone following Asian trail running, and together they trace a deliberate escalation of distance rather than a burst of inspiration.

The telling detail is what Toan said afterwards: he had run the 100 km UTMB and rated Tor des Géants many times harder. That is a technical judgment from someone inside the sport, and because he has finished UTMB it carries weight. UTMB is the benchmark against which the trail world measures difficulty. When a runner who has cleared that benchmark still calls something many times harder, the 330 km figure needs no adjectives to feel heavy.

The speed equation and the gradient equation

Divide distance by time and the men's winner averaged roughly 5.0 km per hour on mountain terrain. Toan averaged about 2.4 km per hour. Hang also about 2.4. At a glance, a gap of two and a half times looks like a chasm. Placed in the terrain, though, that number is not measuring the same thing as speed on flat ground.

Read it vertically instead. With more than 24,000 metres of gain across 330 km, each kilometre carries an average of 72.7 metres of climbing. A quarter of that would turn a park jog into a stair session. The winner climbed 364 metres per hour. The two Vietnamese climbed 173 to 174 metres per hour, steadily, for almost six days.

The total gain is equivalent to two point seven times the height of Everest, accumulated. And it is not concentrated in one section: more than 20 passes above 2,000 metres are scattered along the loop, meaning the body repeatedly enters and leaves mild oxygen deficit, repeatedly changes heart rate, repeatedly changes layers as the sun drops.

That is why 138 hours must be read as a measure of endurance, not of speed. The organisers set the cut-off at 150 hours, and the two Vietnamese finished 11 to 12 hours inside it, roughly 7 to 8 percent of the available time budget. In a race with a completion rate around 60 percent, an 8 percent buffer is thin safety, not leisure.

Break it down further. Seven large support stations, roughly 50 km apart. At 2.4 km per hour, each segment equals about 21 hours of movement. The real tactical unit of this race is not a day or a night; it is 21 hours of self-sufficiency between two resupplies. Water, food, headtorch batteries, dry layers, medication, and above all the decision of when to stop, all have to be settled before leaving a station. A bad call at the fourth station surfaces at the sixth, 100 km later.

Sleep has to be counted too. 138 hours 40 minutes is five days, eighteen hours and forty minutes. At three hours of sleep per day, that is about 17 hours in total. At four hours, about 23. The remainder is actual moving time, which explains why in ultra trail the greatest skill is not running fast but sleeping at the right moment and waking at the right moment.

The seventy-hour gap

The men's winner finished about 72 hours ahead of Toan, three full days. The women's winner finished about 71 hours 30 minutes ahead of Hang. The ratio of the Vietnamese pair's time to the winning time is roughly 2.1.

That number needs placing correctly. It says Zhao and Hartmuth belong to the professional tier of world ultra trail, while Hang and Toan belong to the mid-to-back finisher cohort, the people who survive the test rather than contest the placings. In a race where four in ten starters drop out, being among the six in ten who finish is a real, recordable result that needs no inflation.

But there is one detail in the results sheet that matters more than the mere fact of Vietnamese presence. Hartmuth finished 1 hour 15 minutes behind Zhao over 330 km. As a proportion, the gender gap at the front of this race is under 2 percent. In the road marathon, the women's world record is roughly 7 to 8 percent slower than the men's. Over 330 km and more than 24,000 metres of climbing, the gender gap at the front compresses below 2 percent, where the road marathon figure usually sits around 7 to 8.

That is a structural fact about the sport, not a courtesy compliment. When distance grows long enough that the decisive factor shifts from power output to energy management, sleep management and pain tolerance, male physiological advantage loses weight. Races like this are among the few arenas where women close on the men's front systematically, rather than through one exceptional individual.

In the same table, the gap between Hang and Toan is 50 minutes across 138 hours, about 0.6 percent. Two Vietnamese, one woman and one man, finishing almost together after nearly six days in the mountains. I have no data to claim they paced or supported each other. But looking at the numbers, one thing is plain: at this distance, a female runner and a male runner are no longer a question of gender in sport, but of who prepared better.

Where the data goes quiet

There is a gap in the reporting I cannot ignore: no placings, no split times, no ages, no injury or medical history. For a human-interest piece, that absence is a reasonable editorial choice. For a performance analysis, it is a hole.

Without splits, pacing quality cannot be judged. A runner who finishes in 138 hours on even pacing is a completely different athlete from one who finishes in 138 hours after collapsing at kilometre 200 and recovering. Those two stories support opposite conclusions about real ability, and the report gives us no tool to tell them apart.

Without placings, we cannot know where the two Vietnamese sat in the field. With a 2.1 ratio to the winner, it is reasonable to infer the back half of the finishers, but inference is inference. Dropping placings is a common habit in Vietnamese sports reporting when the subject is not near the front. I understand the pressure; I do not like it.

And there is a second silence, more important. Toan described narrow paths with a rock face on one side and no safety ropes. In 2026 a runner died falling on similar terrain. Not one line in the report covers mandatory equipment rules, medical procedure at stations, or how the organisers manage the unroped sections. That is the audit Vietnamese sport almost never performs on adventure disciplines: we celebrate who finishes and rarely ask what nearly stopped them.

I have watched athletics and endurance sport for forty-seven years, long enough to see a pattern. Every time a Vietnamese athlete does something abroad, the questions are about feelings, hardship and pride. Very rarely: what are this race's safety rules, who is liable if something happens, and did our athlete prepare for the worst case. This is not gratuitous severity. In a race with a fatality precedent, the safety question belongs before the glory question.

The audit nobody performs

Look at the economic structure behind two finish medals. These are high-level amateurs: no national team, no named head coach, no training centre, no published nutrition programme. Flights to Italy, equipment, food and lodging for nearly a week in the mountains, insurance — all of it sits outside any state sports budget line.

I did the investigation into gender funding gaps in 2026, when Christine Sinclair wept in Tokyo not over a win but over Canada's women receiving one eighth of the men's funding. That piece forced the Canadian federation to raise the women's budget by 25 percent. I bring it up because the structure here is identical, only the scale differs: an individual's achievement is celebrated while the system stands aside and pays nothing.

That audit raises three concrete questions. Who pays for a Tor des Géants entry, and if the athlete pays alone, is this an individual result or a national one. If Vietnam has a trail scene deep enough to produce finishers at the world's hardest race, why is there no published support fund for distances of 100 km and beyond. And who profits from these finishes, and do they return any of it to the domestic trail community.

I am old, but every call from them makes me young again. In 2026, when the national women's league was cancelled after four rounds and I stopped writing for 54 days, Nguyen Thi Thanh Nha video-called me wearing a flour-dusted shirt, showing off 100 loaves of bread she had baked to fund her passion. She only made one video call, but it pulled me off the bottom. I tell that story here because it is the reason this piece is not written as a tribute. If I wrote a tribute, I would slide back into exactly the habit a nineteen-year-old pulled me out of.

What remains after the finish line

Three Vietnamese entered, two finished, one stopped on the way. The one who stopped lives in France, far closer to the Alps than the other two. That is the detail I keep longest, because it breaks a familiar assumption: being near mountains does not mean being prepared for them. Geographic proximity cannot substitute for weeks of adaptation to altitude, night cold and steep ground. Toan and Hang, training in tropical lowlands, were the two who finished.

Which says the decisive factor at this distance is preparation structure, not postcode. It also says Vietnam's trail scene has accumulated enough depth to produce people who finish the world's hardest race. Prenn Trail 250 km, Son La Ultra Trail, VMM — the names on the two finishers' résumés are their real training system. No federation stands behind them, but a domestic calendar thick enough to raise them does.

For me, the value of this result is that it turns an abstract idea into a checkable number. 330 km. More than 24,000 metres of climb. 150 hours. A 60 percent completion rate. 138 hours 40 minutes. When a woman who once sold lottery tickets in Vung Tau and a man who has run UTMB stand together among the six in ten who finish, the interesting question is not that they did something extraordinary, but how many other Vietnamese sit close to that threshold with nobody recording their names.

I will keep following the domestic trail calendar, not to count medals but to see whether anyone repeats this result twice. One finish is a story. Two is a sport. And once there is a sport, the next question stops being whether they can finish, and becomes who will pay so they do not have to pay alone.
