Ekiden 2026: Three Vietnamese Cities, Five Years, and the Number Nobody Has Counted Yet

In April 2026, a run from Kyoto to Tokyo covered roughly 508 kilometres across 23 stages. At each handover, a runner passed the next one a strip of cloth known in Japanese as the tasuki. According to the standard account of the Japanese relay tradition, the word 'ekiden' is built from two parts: 'eki', meaning station, and 'den', meaning transmission. There is no running inside the word itself. What it holds is a messaging system: where a horse or a walking courier once moved, a runner now does, and at every station responsibility changes hands. On 20 September 2026, when the fifth season of AEON Vietnam's ekiden closed its final stage in Tay Ninh province, what I went looking for on my phone screen was exactly that handover. What I found was not a strip of cloth but a ledger. The ledger is simple. AEON's cultural and sporting programme in Vietnam began in 2026 and reached its fifth season in 2026, again split into three stages across three regions. The first stage came to the northern port city of Hai Phong on 21 June 2026; the second to the historic central city of Hue on 19 July 2026; the last to Tay Ninh in the south-west on 20 September 2026. For Tay Ninh this was a first — no stage of the five-year series had ever been held in that province. The day runs from a morning race and Vietnamese-Japanese cultural exchange stalls to an afternoon AEON Cosplay Festival with its Talent and Catwalk competitions. The cultural share includes folk games such as chopstick picking and ring tossing. AEON Vietnam says the programme has now reached five cities nationwide. The race format has shifted over time. In 2026 there were two divisions: Division A for families, requiring at least one child aged five to twelve; Division B for teams of members aged thirteen and above. In AEON Vietnam's own framing, the split is meant to bring Japanese relay culture closer to everyday Vietnamese life. There is also a new medal: this year's is built on a 'Collectible Series' concept, in which the building engraved on the medal changes each year so the memory of each season accumulates in one box. Inside the company's long-term structure, the event sits under the social pillar of sustainability, alongside environmental and economic work. Now to the mechanism, which someone who keeps relay records notices first. The engine of an ekiden is not the cloth but the accounting of the handover. A road race averages times; an ekiden adds them. Four runners can post fine individual splits and still lose if the changeover zone eats the clock. In athletics, a 4x100 metre relay grants a 30 metre exchange zone, and what happens inside those 30 metres often decides the colour of a medal. Individual split times do not win a relay; clean exchanges do. Back in 2026 I had already built myself a split-times sheet before anyone asked for it, timing starts frame by frame off broadcast video, as I had done with Shirin Akter's 100 metres from Rio 2026. That habit says something plain: when the tasuki hits the ground, the team's rhythm changes, and live television rarely captures the shift. Division A, read closely, is a design for habit rather than for competition. When a child of five to twelve and an adult form the same team, the child meets running not as a sport but as family work. The question is whether a country's running culture is built from elite athletes' times or from the number of children walking a kilometre with a parent on a Sunday morning. Those of us working in track and field keep the two accounts separate, but when institutional money funds an event like this, the second almost never arrives without the first. The 'Collectible Series' medal reads to me more as business than as running. Change the building on the medal each year and it stops being an object and becomes an incomplete set, and an incomplete set creates an obligation to return. It is the cheapest and most effective retention design available. The unhappy part is that press material usually reports total attendance, when the share of people who come back is the number that actually measures anything. The choice of three cities is not accidental. Hai Phong is industry and port, Hue is heritage and tourism, Tay Ninh a border province with its own geographic identity. Running one template across them benefits both sides: a city wins a place in an annual calendar, and the organiser wins a new audience. The sports-tourism model I have watched in major leagues and Olympic cycles here has a quieter, domestic version. It is time to be careful with the headline figure. From 2026 to 2026 the programme drew close to 22,000 'luot' — person-visits. In Vietnamese, luot counts entries in a ledger, which is not necessarily the count of individual people: one person attending three seasons counts as three. Over four seasons at three stages a year, that averages a little over six thousand visits annually. It is not a bad number, and it is not a vast one either. Corporate social investment races do not produce Olympic-class distance runners; they produce habitual runners. That is worth something, but it cannot be sold as a sporting revolution. AEON's event has, so far, no strict competitive handover stages; the family division deliberately softens the mechanism. And that is probably why it survives, even while carrying the name of an ekiden without the teeth of one. My own working method has a rule about prediction: give a date, give conditions, give a confidence level. In June 2026 I published a five-year forecast so that it could be checked later, and that habit now makes me judge any sporting programme in the language of dates and conditions rather than enthusiasm. Looking from here towards Bangladesh, one thing stands out: running there remains largely individual, with almost no team-relay base built around classrooms or families. If an institution there copied this template with three divisional rounds and a children's division, a fixed annual date in the local sporting calendar would be a reasonable expectation within two seasons. That is an estimate, not a commitment. I will close with a dated, falsifiable forecast. If AEON Vietnam keeps three stages a year and adds at least one new city annually, its cumulative person-visits should pass 45,000 to 50,000 by 2030, with my confidence at 60 percent. Two conditions would prove me wrong: a cancelled stage in any year, or visibly lower attendance in a new host city against the previous average. The real answer, though, sits elsewhere. The eight-year-old who took the tasuki in Division A in Tay Ninh in 2026 — will she still be running in 2036, at eighteen? That single number weighs more than a thousand press releases.
