HDBank Green Marathon 2026: The Can Gio Route and the True Measure of Vietnamese Mass Athletics

Can Gio's September sky was not yet fully bright. I stood at the 5 km assembly area, where a group of middle-aged women bent down to tie each other's shoelaces. No high-mounted electronic board, no international television cameras, no one calling their names over the loudspeaker. Only a few children waiting at the children's race lane, water bottles in hand. One of the women, opening an app on her phone, told her friend: "Once we finish ten kilometres we can still make it to the market." That sentence, to me, weighs more than every press release about this race. When the stadium stands empty, ordinary voices suddenly become leaders. HDBank Green Marathon 2026 enters its fifth season not with a national record crashing down. It begins with a woman calculating the distance back to the market. The race is scheduled for September 2026 in Can Gio District, Ho Chi Minh City, organised by HDBank in partnership with Unique Company, under the technical guidance of the Ho Chi Minh City Athletics Federation and the municipal Department of Culture and Sports. The distance structure covers 5 km, 10 km, a 21 km half marathon and a 42 km marathon, alongside children's and team categories. The route runs through a mangrove forest recognised by UNESCO as a World Biosphere Reserve, and has been certified by AIMS - the Association of International Marathons and Distance Races. In Vietnam, AIMS certification carries concrete technical meaning. It is the condition for a distance-running mark to be recognised, and at the same time a commitment on course measurement and safety. With thousands of participants each season, a few hundred metres of error on the course is not merely a measurement issue. It is a matter of trust. I have followed community races in central Vietnam for many years, and what I watch is not who wins. I watch which starting waves are crowded, which are empty, and who stands in them. At most races I have attended, the 5 km and 10 km waves show a markedly higher share of women than the 42 km wave. The longer the distance, the fewer the women. The problem does not lie in innate physiology. It lies in time - who can afford two uninterrupted hours in a single day for themselves. 45 minutes on the sidelines, a lifetime that never grows old. In Can Gio, that sideline window is precisely the moment a woman ties her friend's shoelaces, and also the moment the entire meaning of a community marathon is redefined. The most analytically interesting feature of the Can Gio course is its terrain. The route passes through mangrove forest, along rivers and the coast, not over uniformly flat tarmac. The surface carries sand, tree roots, and the high humidity characteristic of southern mangrove zones. For a 42 km runner, this is a pacing problem rather than a speed problem. On flat tarmac, a runner can hold a steady rhythm and calculate negative splits. On sand interlaced with roots, every stride costs more energy, the stride shortens, and heart rate climbs at the same speed. The direct consequence: runners tend to go faster than their real capacity in the first 10 km, then blow up around kilometre 30. This is the most common error among Vietnamese recreational runners at marathon distance, and Can Gio is the environment that exposes it earlier. AIMS certifies distance, but AIMS does not flatten the ground. Certification only confirms that the course is the exact number of metres required. It does not confirm that the course is easy. Participants need to read those two pieces of information separately. The distance structure is also worth noting. Including 5 km, 10 km, 21 km, 42 km, children's events and team events simultaneously shows the organisers are targeting a broad band of abilities. The 42 km serves as a flagship - it creates a tier of serious runners who use the race as an annual training milestone. That is the group that generates genuine running culture, not the largest group. Based on my experience following long-distance races, a community marathon distance only holds real value when a group of runners returns the following season. Registration numbers indicate media appeal. Returning-runner numbers indicate the health of the movement. Those are two different indicators, and in its fifth season this race only begins to reveal the second. The second factor is the digital component. The event includes a "Green Marathon online" format allowing remote participation with distance recorded via app. At the same time, HDBank's digital banking ecosystem - app, electronic KYC - is integrated into the race experience. From a training standpoint, this cuts both ways. On one hand, it extends runners' activity cycle beyond race day. Instead of a four-week block and then rest, runners have reason to maintain volume year-round. On the other, it creates an unverified category of performance - app-recorded distance passes no officiating, has no standardised course, and no uniform terrain conditions. I call it the technical grey zone of the digital running movement. It helps sustain habit, but if runners mistake it for competitive performance, they will deceive themselves about their real ability. The third factor is the environmental component. Across previous seasons, organisers recorded more than 2,000 trees planted and beach clean-up activities. Choosing Can Gio as the venue is deliberate: this is a biosphere reserve, so every environmental impact of the race is scrutinised more harshly than at a city-centre race. HDBank has sponsored sport for more than 36 years, including football and running. That long-term presence does not directly produce elite athletes, but it produces organisational infrastructure - precisely what Vietnamese athletics lacks most acutely at grassroots level. From a system perspective, a race like this sits upstream in the chain. It brings children into a kids' category, families into team events, and people who have never run beyond 5 km to a starting line. Only from that source can half-marathoners, then marathoners, then - with luck and a sufficiently good training system - high-performance athletes be filtered out. Let me be blunt: a community marathon does not produce national records, and should not be judged by that standard. The real issue lies elsewhere. Vietnamese running in recent years has tended to measure race quality by media scale and sponsor brand value. "Green" has become an appealing label, "digitalisation" a mandatory bullet point in press releases. If planted trees are only announced without independent verification, and if the app only records distance without any feedback mechanism on movement quality, that label will wear thin. Looking at the scoreboard, I learned to read what is not recorded. A community race's results sheet does not record the drop-out rate at kilometre 30, the number of injuries at 42 km, or the share of returning runners the following season. Those are the three indicators that measure the true health of a running movement. Any organiser bold enough to publish them is doing serious work. One more point. The absence of an invited elite field means the race carries no performance value. In exchange, it reduces competitive pressure for the mass of recreational runners - people who, if placed in an event with stars, would lose their sense of safety. For someone running 10 km for the first time, a sense of safety matters more than a sense of excitement. What I want to see in the sixth season is not a big name brought in for an exhibition run. I want to see the return rate, the number of women moving from the 10 km wave up to 21 km, and an environmental report with independent verification. A community race does not need to be a major event. It needs to be an honest measuring stick. And the question I keep after every Can Gio season is very simple: beyond rising registration numbers, how many of those people are still running next March?
