330 km, 24,000 Meters of Climb and the 70-Hour Gap at Tor des Géants

At altitudes above 2,000 meters, some sections of the trail are so narrow that two runners cannot move side by side. On one side the rock drops away, and by Lưu Đức Toản's own account, those sections have no safety ropes. He said a single misstep would leave nothing to catch you. People usually picture ultra trail running through stamina, willpower and legs that refuse to tire. But when I set the Tor des Géants results sheet next to that recollection, what struck me was a different kind of gap. Lưu Đức Toản finished in 137 hours 50 minutes. Lê Thị Hằng finished in 138 hours 40 minutes. Same 330-kilometre course, same more than 24,000 metres of cumulative climbing, same more than 20 passes above 2,000 metres. The men's winner, Jia Ju Zhao, finished in 65:55:22. The women's winner, Katharina Hartmuth, finished in 67:10:09. The gap between the front of the race and the two Vietnamese runners is roughly 70 hours, on a course with a 150-hour limit. What deserves attention is that inside that enormous gap there is an improbably small one. A Vietnamese woman and a Vietnamese man finished exactly 50 minutes apart, after 330 kilometres and more than 24,000 metres of climbing. In a race where roughly 40 percent of starters do not finish, both finishing is one story; both finishing almost together is another. The gap on the field is a living thing, and it changes the moment someone dares to believe. Tor des Géants, literally "Tower of the Giants", was created in 2026 in Italy's Aosta Valley. Its format differs fundamentally from almost every race Vietnamese runners know. It is a single stage, run continuously, with no daily divisions and no mandatory rest hours. Athletes decide when to run, when to sleep and for how long, and carry responsibility for every such decision. Seven major support stations sit along the route roughly 50 kilometres apart, offering food, water and medical assistance. That structure turns Tor des Géants into a test of self-management rather than a pure speed race. The 50-kilometre spacing becomes the basic tactical unit: each segment is a problem in water, salt, energy and temperature. The 150-hour cut-off is an absolute boundary. Organisers' statistics indicate only about 60 percent of starters finish. Put another way, for every five people on the start line, two will not complete the course. This year's event ran from 13 to 19 September. Three Vietnamese runners took part. Two finished; one withdrew mid-race, and that athlete lives in France. That last detail matters more than it appears: living near the Alps does not mean being prepared for the Alps. The finishing records show neither athlete is new to this discipline. Lê Thị Hằng, from Vũng Tàu, has completed Prenn Trail 250 km, Son La Ultra Trail 100 km and Vietnam Mountain Marathon 100 km. Lưu Đức Toản has run UTMB, Mantra 116 km, ULJU Trail 9 Peaks 100 km and Mt Fuji 100 km. This is a deliberate, multi-year escalation, not an impulsive gamble. Toản himself offers the most interesting technical judgement in the whole story. He has completed UTMB, the most famous ultra trail on the planet, and rates Tor des Géants as many times harder and more challenging. It is a first-person assessment and therefore subjective, but his UTMB finish lends it weight. To read 137:50 and 138:40 correctly, one must first accept that elapsed time here is heavily loaded by terrain and altitude. More than 24,000 metres of cumulative gain is roughly equivalent to climbing from sea level to the summit of Everest nearly three times, except that after each climb you must descend again. More than 20 passes above 2,000 metres mean the body swings between daytime heat and the cutting cold of high-mountain nights. In those conditions, finishing time measures toughness, not speed. Comparing it with road times or personal bests on tarmac is a technical error. And for that reason, two Vietnamese runners finishing in about 138 hours speaks to endurance and risk management, not yet to their position in the global speed hierarchy of ultra trail running. One point most domestic coverage tends to glide past needs to be stated plainly: a finishing time roughly double the winners' places the Vietnamese pair in the mid-to-back finisher cohort. The front of Tor des Géants is made up of specialist professional ultrarunners who can keep moving for days with almost no sleep. The two Vietnamese athletes are high-level amateurs with formidable foundations. Different categories, different objectives, and blending them into one comparison produces wrong conclusions. The 150-hour limit shows the safety margin for both finishers. Toản came home 12 hours 10 minutes inside the cut-off. Hằng came home 11 hours 20 minutes inside it. That is a margin, not a comfort zone. One long stop at a support station, one minor knee or foot injury, one extended bout of hypothermia could consume all of it. Those of us who have stood on the coaching side tend to look at the margin before the absolute time, because the margin reveals how well resources were allocated. Seven support stations roughly 50 kilometres apart set the tactical rhythm. Each segment is a closed cycle: leave a station with enough water and fuel, handle the terrain, manage temperature, and arrive at the next station still lucid enough to make decisions. An error in the second segment can carry consequences into the fifth. Over a distance more than seven times a marathon, accumulated error is a bigger enemy than any single climb. The hardest technical element at Tor des Géants is that nobody forces you to do anything. No stages, no mandated rest, means athletes must decide when to sleep. Too little sleep degrades cognition, makes night navigation unreliable and raises the risk of a slip on rock. Too much sleep eats the safety margin. The line between those two errors is far narrower than the 50 minutes separating the two Vietnamese runners. Based on my experience following ultra-distance races and conversations with East African athletes in Iten, I believe the most neglected variable here is altitude. Iten sits at about 2,400 metres above sea level. Kenyan athletes live, eat, sleep and train there year-round, so altitude is their baseline rather than a challenge. Vietnamese athletes mostly train in tropical lowlands, where the body adapts to heat and humidity rather than to moving hard while short of oxygen for days on end. Public records do not say whether these two athletes completed an altitude acclimatisation camp before the race. If they did not, much of the time gap should be read as the cost of adaptation rather than the cost of talent. This runs against the reflex of a sports world that attributes every performance difference to personal quality rather than training conditions. Asking how an athlete was trained to read the course is always more useful than judging whether they were fast or slow. A 50-minute gap between a female and a male athlete over 330 kilometres is notable, though it needs careful handling. Over extreme distances the gender gap usually compresses, but the compression here is strong. One plausible hypothesis is that the two ran together or supported each other for much of the race, sharing pace, aid packages and sleep decisions. If so, it is a model of tactical cooperation worth studying rather than two individual results placed side by side. The third Vietnamese entrant's withdrawal is the necessary dark side of the story. That athlete lives in France, with the obvious geographic advantage of being near the Alps, and still did not finish. Being near mountains does not create the capacity to withstand them. Altitude adaptation, rock-terrain skill, experience sleeping in the cold and the ability to decide well while exhausted are separate skills that must be trained, not absorbed through proximity. On data, what is publicly available is thin. There are no split times, no final placings for the two runners, no ages, no injury histories, no detailed pacing tables. The absence of splits makes assessing pacing quality impossible. We know they finished, we know they finished in about 138 hours, and that is nearly all that can be asserted with confidence. That gap creates the familiar trap of sports media. When two Vietnamese runners appear in the same line as two champions, readers unconsciously place them in the same tier, when the real distance is 70 hours. Omitting placings and split data suits human-interest storytelling, but it also lifts public expectation above reality. The gap on the field is a living thing, and it changes the moment someone dares to believe. The counter-intuitive point is this: the most important signal in the story is not the two individuals but the domestic calendar behind them. Prenn Trail 250 km, Son La Ultra Trail 100 km, Vietnam Mountain Marathon 100 km, ULJU Trail 9 Peaks 100 km, Mantra 116 km. That list shows Vietnam already has a genuine ultra-trail system, with 100 km and even 250 km distances, capable of developing athletes before they step onto the international stage. A country cannot produce a Tor des Géants finisher on recreational running alone. Set that system beside the Kenyan model and two different roads appear. Kenya generates depth through numbers: thousands of athletes training at altitude, eating, sleeping and suffering together, and from that mass the fastest people in the world are filtered out. Vietnam currently generates points of light through self-funded individuals who buy their own tickets to the hardest races on earth and bring back a story. The Kenyan model produces champions. The current Vietnamese model produces inspiring narratives. Both have value, but they cannot substitute for each other, and applying one model's standard to the other is an analytical mistake. The most serious blind spot in the whole story sits in the risk section. In 2026, an athlete named Yang Yuan died at Tor des Géants after slipping, falling and sustaining a head injury. Toản's account of narrow paths without safety ropes directly corroborates the mechanism behind that risk. In a race with a fatality precedent, reporting purely in the language of conquest while omitting safety context is a shortcoming, because it quietly lowers the guard of those considering the attempt. Jia Ju Zhao's men's victory is also a signal beyond Vietnam's borders. An Asian athlete leading one of the harshest ultra trails on earth shows that the perceived ceiling for Asian athletes in this discipline is shifting faster than participation numbers suggest. Vietnam's appearance on the finishers' list should be read inside that continental trend, not as an isolated phenomenon to be celebrated. So what should be tracked from here? First, repeatability. One finish does not establish a level; three finishes across two seasons, especially in the top third of the field, would be evidence of real movement. Second, safety rule changes by the Tor des Géants organisers, because mandatory roping on cliff sections would change the event's risk profile and, with it, athlete preparation. Third, the growth rate of the domestic ultra market, measured in new races, entry numbers and the arrival of certified distances. What I want to keep from all of this is not the image of two Vietnamese runners touching the finish line. What I want to keep is an unanswered question: if these two trained year-round at 2,400 metres like the athletes in Iten, would that 70-hour gap narrow, or would it stay exactly where it is because it measures the distance between two training models rather than between two people? Answering that is the hard work, and it is the work worth doing next. The gap on the field is a living thing, and it changes the moment someone dares to believe.
