The Course: A Green Campus, But an Unknown Route
The BTN UI Green Marathon takes place on Sunday, 9 August 2026, inside the grounds of Universitas Indonesia in Depok, Jawa Barat, an area runners flag as characteristically shaded and leafy [4]. Four distances are on offer — 5K, 10K, Half Marathon and full 42.195km Marathon — giving the event a genuine full-slate spread rather than just a fun-run add-on [4].
What nobody can tell you yet is exactly how the tarmac unfolds, because this is the first time the race has run. A runner discussing the calendar on Threads was blunt about it, saying they could not yet guess the route since it was the event's debut year, though they expected the half marathon category to loop around the UI campus [6]. Until organisers publish a course map closer to race day, treat any route assumptions as educated guesses rather than fact.
The Sustainability Pitch
University communications frame this as more than a bib-and-medal event — Humas UI describes it as a premiere marathon event built around a mission of supporting sustainability and environmental preservation [3]. That messaging matches what's circulating among runners ahead of race day.
One follower on Threads summed up the appeal directly, describing the event as genuinely applying a zero-plastic approach and planting a tree for every runner [7]. If organisers deliver on that promise at scale, it would set this race apart from Indonesia's more disposable-cup-heavy road events — worth watching for on the day itself rather than assuming from marketing copy alone.
Organisation & Logistics
The race is a joint production between Universitas Indonesia and Bank Tabungan Negara as Platinum Sponsor and Marathon Presenting Partner, with IM Road Runner handling event management [2]. Ticket sales opened through the balé by BTN app from 17 July 2026, with a 10% discount available to those who book that way [5][2].
Cut-off times are tiered by distance: one hour for the 5K, two hours for the 10K, four hours for the Half Marathon and six-and-a-half hours for the full Marathon [4]. Note that the coveted 42K finisher jersey is not automatic — marathoners only receive it if they cross the line inside the cut-off, so slower finishers should plan their pacing accordingly [2]. Entry-level pricing starts from IDR 350,000.
Age rules are worth checking before you register: the 5K Fun Run allows entrants from 13 years old, while the 10K, Half Marathon and Marathon categories require a minimum age of 17 [1]. Podium places, however, are reserved for Indonesian citizens (WNI) only, so foreign runners can race but won't be competing for the top-three prizes [1].
Atmosphere: Inaugural Energy, Community Feel
Because this is a debut, there's no returning-runner buzz to draw on yet — no war stories about crowd support or finish-line chaos. What does come through on social channels is a sense of anticipation tied to the university-community angle, with locals discussing it alongside other UI-linked running events on the calendar for the year [6].
Benefits for finishers include a race jersey, finisher medal, goodie bag, e-certificate and top-three prizes for both male and female fields in the competitive categories, which is a fairly standard but solid package for a first-year event [2].
Should You Run It?
If you're based in or near Jakarta/Depok and like the idea of supporting a campus-rooted, sustainability-focused race with a bank and university behind the logistics, this is a reasonable one to try — the cut-off windows are generous enough for most recreational finishers [4]. If you're travelling specifically for a marathon PB attempt on a known, well-reviewed course, wait a year or two until race reports and route maps exist; right now you're registering on trust in the organisers rather than on evidence from past editions.
