What We Actually Know About the Course
The essentials are locked in: flag-off is 3:30am on Sunday 11 October 2026 at Marina Barrage. The event is scheduled for 11 October 2026 at 3:30 AM at Marina Barrage, Singapore. [1] Three distances sit on the entry form, with the half marathon as the headline category alongside 5km and 10km options. The race runs from Marina Barrage with a 3.30am flag-off for the 21.1km competitive category, with 5km and 10km fun runs alongside it. [1]
Worth noting before you register: this is a JomRun production, not a rebrand of Singapore's national marathon. The organiser makes clear that the event is run by JomRun Pte Ltd and is separate from the BYD Singapore International Marathon, which is organised by a different company. [1] If you're comparing race listings online, that distinction matters more than it sounds.
Racing Before Sunrise
The pre-dawn timing isn't incidental — it's the point of the whole event. A half marathon that finishes before the sun is properly up is a materially different race from one that doesn't, and in October that gap is worth several minutes over 21.1km. [3] For anyone who has suffered through a mid-morning Singapore half, that's a real difference in how the last 5km feels.
Where this race sits on the calendar is arguably its biggest selling point. An 11 October half lands roughly eight weeks out from the BYD Singapore International Marathon, close to the textbook slot for a tune-up race. [3] Run it sensibly and it becomes a pacing rehearsal rather than a race that eats a week of recovery. Held at goal marathon pace plus 10 to 15 seconds per km it works as a rehearsal; go flat out and you're effectively trading a strong December race for a fast October one. [3]
Entry Tiers and What's in the Pack
Pricing starts at a deliberately quirky number. Entry begins from SGD 88.88. [1] The 5km and 10km categories are billed as non-competitive fun runs rather than timed races, which broadens the appeal beyond serious half marathoners. Alongside the 21.1km competitive run, there are 5km and 10km fun run categories for those not chasing a podium. [1]
Entitlements scale with distance. Fun-run entrants get an event jersey, finisher medal, e-certificate and light refreshments, but their bib carries no timing chip. The 5km category includes a Puma event jersey, finisher medal, race bib without a timing chip, e-certificate and light refreshments. [1] The half marathon field gets the serious kit: a separate finisher jersey and proper electronic timing. Runners in the 21.1km category additionally receive a Puma finisher jersey and a race bib fitted with a TrackAsia RFID timing chip. [1]
One Race in a Crowded JomRun Calendar
Marina Barrage is JomRun's go-to venue in Singapore, and this half marathon shares the address with a string of lighter, character-branded fun runs the same organiser puts on through the year. The One Piece Run Powered by JomRun is one such event drawing fans of the anime series to the same venue. [2] That pattern — themed merchandise, entry-level distances, high entitlement counts — tells you what kind of company is behind the half marathon too: volume-driven and merch-forward rather than elite-focused.
For scale, it's worth knowing what sits at the other end of Singapore's calendar. The BYD Singapore International Marathon is held on the first Sunday of December and is capped at 55,000 runners. [4] It also carries World Athletics Gold Label status. [4] The JomRun half marathon makes no claim to that scale or pedigree — it's a smaller, more accessible commercial event that happens to land usefully on the training calendar rather than compete for the spotlight.
Should You Run It?
If you're marathon-training for December and want a cheap, cool, well-timed half to test fitness without wrecking your taper window, this fits the brief neatly. Sitting roughly eight weeks before the BYD Singapore International Marathon, it lands close to the ideal spot for a tune-up race. [3] Casual runners drawn to low-pressure 5km or 10km outings with a jersey and medal at the end will also find it an easy, affordable entry point. With entry from SGD 88.88. [1] Just don't expect Gold Label polish or big-city theatre — go in knowing it's a straightforward, well-priced pre-dawn half rather than a marquee event.
