Van Trang and the 42km at Y Ty: 4 Hours 26 Minutes on Lao Than Summit, and the Crowd's Misplaced Debate

4 hours 26 minutes is the number that appeared on the timing board in Y Ty on the afternoon of September 6, 2026, when Van Trang crossed the finish line of the 42km category at the Y Ty Mua Vang race. She won the women's field. She also finished second overall, behind exactly one male runner. On a course with more than 1,300m of cumulative elevation gain, reaching a high point at the summit of Lao Than at 2,860m above sea level, that result was not built on luck. Standing on the podium, with the misted mountain range behind her, Van Trang did not talk about her legs. She talked about breathing. I sat in front of a screen in Saigon, rewound the on-site interview, and wrote her answer into my notebook: "On the 42km there were climbs that nearly drained my body. At that moment I just focused on the stretch of road in front of me, kept my breathing rhythm, managed my effort and refuelled at the right time. I kept telling myself: stay calm, as long as you have energy you still have a chance." I have kept that note-taking habit for nearly half a century. People see a race course; I see destinies taking one step at a time. And the story at Y Ty this time has two halves: one half sits on the timing board, the other sits in running groups online, where people are discussing the chest of a champion. The first half needs to be stated clearly, because it is usually glossed over. I began following mountain running races in northern Vietnam in 2026, when I first sat down to take notes at a small trail race on the routes around Sa Pa. Based on my experience following trail races across nine seasons, I have drawn one conclusion: over 42km of mountain terrain, people do not beat each other on the climbs. They beat each other on the flat sections. The flat sections are where every runner believes they can accelerate, and also where the majority destroy the pacing plan they set three months earlier. Before dissecting the numbers, I need to rebuild the context for anyone who has never stood at a mountain start line. Y Ty Mua Vang is a trail running event held in Bat Xat district, Lao Cai province, in Vietnam's northern border region. The 42km course is designed as a loop up to the summit of Lao Than and back. Cumulative vertical gain on this course is above 1,300m. What the trail community calls D+ is the total metres climbed that the legs must carry, not counting the descents. That figure matters more than the distance, because 42km on flat ground and 42km with 1,300m of D+ are two different sports, even different in the energy systems the body recruits. Over 42km of flat ground, the body runs mostly in the aerobic zone, fuelled by muscle glycogen and stored fat, with a stable heart rate and a clear head. With 1,300m of climbing, every steep pitch forces the quadriceps and glutes to work at higher intensity, heart rate spikes, and the body switches to burning glycogen many times faster. Without control, a runner runs out of fuel around kilometre thirty, with twelve kilometres still to go and nobody left to chase. Thin mountain air is the second variable. Above 2,000m, the partial pressure of oxygen drops, so each breath delivers fewer oxygen molecules than at sea level. For a runner living in Hanoi, the body gets two or three days to adapt, and usually that is not enough. This is why many runners with beautiful gym numbers still break down at Y Ty. The summit of Lao Than at 2,860m is the highest point of the course. From the top, the descent is steep, with loose rock, and in my experience the descent is where time is lost. The muscles are already fatigued after the climb, the shock absorption of the thighs is reduced, and every misplaced step has a cost. I once watched a male winner of a 70km category at another regional race lose forty minutes on the final descent alone. He had spent more than six hours building that advantage. But the question I really want to raise here is something else. 4 hours 26 minutes over 42km of mountain terrain, with more than 1,300m of D+, works out to an average pace of roughly 6 minutes 20 seconds per kilometre. If anyone reads that number and finds it unremarkable, allow me to repeat it: 6 minutes 20 seconds per kilometre is the pace of a trained road runner, not of a person climbing a mountain. And that is the average across the whole journey, including the steep sections where even a fast walk is an achievement. At similar-scale trail races in Vietnam that I have followed, a reasonably strong amateur male runner who trains consistently three sessions a week for a year typically completes 42km with roughly 1,300m of D+ in about 5 hours 30 minutes to 6 hours 30 minutes. The strongest in that group can go under 5 hours. The 4 hour 30 minute mark is a boundary most men never touch. Van Trang was born in 2026. She is a mother of four. She lives in Hanoi. She is not a professional athlete, has no nutrition team, no dedicated sports physician, no training-data analyst. She arranges her running schedule around the schedules of four children. She ran 42km faster than almost the entire male field in the same category, finishing behind one person. I want to pause here longer than usual, because this is the point a conventional race report skips. When a female athlete finishes second overall, the familiar framing calls it an "interesting surprise". I do not use that framing. To me, when a mother of four outruns hundreds of men, the issue is not with her. The issue is with the assumption we still carry when we walk into the arena: that elite endurance is the property of a particular group of people. So what was her endurance built on? In her interview, Van Trang was specific: "Besides running, I combine gym work, swimming and supporting exercises to accumulate fitness day by day." Three key words here are gym, swimming and consistency. Let me explain why these three elements make the difference over mountain distance. First, muscle mass. Over 42km of flat running, a runner wants to be as light as possible, because every extra kilogram is carried for four hours. On steep mountain terrain, the logic reverses. On a climb, most of the propulsion comes from the quadriceps, glutes and calves. If those muscles are weak, a runner is forced to walk sections that could be run, losing time exactly where rivals are not losing it. Gym work builds a strength base for that muscle group. It is why the world's leading trail athletes lift weights, even though none of them look like bodybuilders. Second, swimming. Swimming is a maximal oxygen uptake exercise, meaning it builds the body's capacity to transport and use oxygen under effort. This is the single best predictor of endurance performance known to sports science. Swimming also trains the respiratory system: swimmers must control their breathing against the rhythm of their stroke, and that skill transfers directly to a mountain climb, where you must breathe to the rhythm of your steps. She said "kept my breathing rhythm" in the interview. That rhythm did not appear by accident. Third, consistency. Van Trang said: "This endurance comes from regularity and discipline." This is the statement I believe most in the whole conversation, because it matches physiology. A person's aerobic base is built from accumulated hours at low intensity, not from sudden heavy sessions. Someone running 40km a week for forty weeks will have a better base than someone running 80km a week for four weeks and then stopping with an injury. There is no exception to this rule, in any gender. Reading her answers closely reveals a clearly planned pacing strategy: focus on the stretch in front of you, hold the breathing rhythm, manage effort, refuel at the right time. The trail community calls this principle segment-by-segment running. It runs entirely counter to the instinct of the majority, which is to spend everything when you see someone ahead, then pay for it at the end. I once witnessed this at another trail race on a northern route, when a male runner surged into the lead at kilometre eight to the cheers of spectators, then was passed by four people in the final three kilometres. He told me afterwards that he knew he was wrong, but the crowd was too large to resist running fast. Van Trang had an advantage she probably did not recognise. When the crowd is not looking at you, you are free to run your own plan. That is a form of advantage that comes from being overlooked. It is real in sport. Now to the other half of the story, the part I consider more significant than the medal. Immediately after Van Trang left the podium, her images were posted in several running groups for discussion. The discussion was not about 4 hours 26 minutes. Not about 1,300m of vertical gain. Not about second place overall. It was about her chest, with a mocking phrase attached. I have seen this kind of content many times in more than forty years in this profession. It is not new. What is new is the speed of transmission. Posts about the achievements of a female athlete, in my observation across many seasons, tend to receive modest engagement: a few hundred likes, a few dozen comments, mostly short technical comments from people who actually run. A post mocking a female athlete's body, at the same time on the same platform, typically receives several times, even dozens of times more comments, because every platform's algorithm privileges content that generates dispute. More dispute means more impressions. More impressions means more advertising. This is an economic structure, not a cultural accident. Looking at that structure explains why women's achievements in sport are usually taxed in an invisible way. Five years ago, at 58, I stayed two extra days in Tokyo after the Olympics to interview a Canadian women's football player through a socially distanced window. We cross-checked figures and found the national women's team received a fraction of the men's funding. After the investigation aired, that country's football federation was forced to raise the women's budget by 25 percent. That 25 percent did not come from a revolution. It came from someone sitting down to count. I tell that story here because women's football and women's trail running share a structural feature: both are priced by something unmeasurable instead of something measurable. What is measurable at Y Ty is 4 hours 26 minutes. What is not measurable is how a crowd feels when it looks at a photograph. Van Trang hit back with a line I would print on the wall of every running group: "I run with my legs, not with my appearance, so why drag me into groups to talk about this?" She added: "I'd like to see anyone carry two grapefruits for 42km or 55km of mountain road." That is the answer of someone who understands exactly what she is being questioned about, and chooses not to plead guilty. I respect that choice, and I also understand why most female athletes cannot make the same choice. They are afraid. Afraid sponsors will read it. Afraid of being labelled difficult. Afraid of losing an invitation. Here I want to add something few articles mention: a female athlete's capacity to push back is proportional to her financial independence. Van Trang does not make a living from running; she pays her own entry fees and her own travel. That is exactly why she has the right to speak. A female athlete dependent on sponsorship usually does not. It is why the bravest voices in women's sport often come from outside the professional system. On the clothing question, let me be direct. Compression tops and tights in trail running are not aesthetic choices. They are technical choices. Compression fabric reduces friction between skin and fabric at contact points such as the thighs, underarms and chest — points where friction repeated tens of thousands of times over four hours becomes chafing, and chafing in exactly those places can end anyone's race. Compression also helps manage moisture and heat, keeping the body dry in mountain rain. And on terrain with loose rock and forest, tight fabric has nothing to snag. When someone asks a female athlete whether she should cover up more to avoid prying eyes, the person asking is requiring her to trade physical safety for someone else's mental comfort. That is a one-way transaction. Van Trang answered this question with a line I recorded verbatim: "Sports clothing first of all has to be comfortable and safe. If I changed myself only because I fear gossip, I would probably spend my whole life living by other people's eyes." She said one more thing that I think is the closing line of the whole story: "When people look at a girl on a running course, I hope they see someone striving to conquer her own limits." I have been in this industry long enough to know that statements like that rarely change a crowd on the day. Change comes slowly, and from somewhere else. I went through a very bad stretch myself. In April 2026, when the national women's football season was cancelled after four rounds, I stopped writing for 54 days. I locked my door. One evening a young female player video-called me, wearing a flour-dusted shirt, showing off 100 loaves of bread she had baked herself to fund her passion. She only made one video call, but it pulled me out of the depths. I realised I had mythologised sport too much, while reality, harsh and beautiful at once, was still there for anyone willing to look. That way of looking is what I want to offer readers, not a declaration about civility. I am old now, but every call from them makes me young again. And every time a female athlete crosses a finish line, a prejudice has to retreat one step. That rejected article from years ago, about the pressing game of Japan's U20 women's team, is now the scar I treasure most. I mention it not to talk about myself, but to point to a rule: the real value of women's sport is usually discovered later than the moment it happened. At Y Ty this time, the moment it happened was September 6, 2026. When it is properly recognised, I do not yet know. But there is a way to shorten that gap. If each of us, when encountering a post discussing a female athlete's body, redirects the comment toward the results table, the structure shifts a little. That is not a heroic act. It is a repeatable act, and only what is repeatable can change a structure. Van Trang has declared her next targets: the 70km at the VMM race, and a 100km distance by the end of 2026. A 100km mountain race is territory where the body starts asking different questions, about digestion, about burning fat as the primary fuel, about the limits of will when darkness falls and a headlamp becomes the only source of light. I will follow that journey. And I will keep doing something I have done for many years: checking whether anyone is willing to look at the number before looking at the body that produced it. The pitch taught me that some lessons are never rejected. The mountain is teaching a similar lesson in its own way: you may stay silent through the whole climb, as long as you are still moving upward. And if a mother of four from Hanoi can outrun almost the entire male field on a 1,300m climb, then the remaining question belongs to the audience, not to her.
