BYD Singapore International Marathon 2026: Dates, Distances, Fees and What’s Changed

If you have run Singapore's December marathon before, the first thing you will notice this year is the name. Until 2025 it was the Standard Chartered Singapore Marathon. In 2026 it is the BYD Singapore International Marathon presented by adidas, run by a new organiser, SG International Marathon Pte Ltd, over three days from Friday 4 to Sunday 6 December 2026.

The new name is only the start. The race weekend is longer, there are fewer places, and the two longest races have already sold out. Here is your complete guide to the 2026 edition—race dates, distances, cut-offs, fees and how to reach a 4.30am start line—taken straight from the organiser's own pages and checked on 17 October 2026.

It is still Singapore's only national marathon and, the organiser says, Southeast Asia's only World Athletics Gold Label Road Race. This year, entries are capped at 52,000 across all categories.

Race Dates and Distances: How the Weekend Breaks Down

Friday is the busy day: the Kids Dash runs in the morning, and the 10km and 5km go off that night. The half marathon gets Saturday morning, and the marathon goes on Sunday morning. All four adult races start at the F1 Pit Building and finish at the National Stadium. The Kids Dash starts from the Great Eastern Promenade instead.

Minimum ages count by calendar year of birth. Three more categories sit outside the table:

• Crew Challenge: new for 2026. You sign up as a team of four, each of you runs the full marathon, and teams are ranked on combined time. It is already sold out.
• EFGH National Championships and Professional Field: by qualification only, so they are not open to general entry.

Is It Sold Out? What You Can Still Enter

The two long races are. When we checked on 17 October 2026, the organiser's race pages showed the BYD Marathon and the adidas Half Marathon as fully sold out. The shorter races are still open for now: registration for the Standard Chartered 10km, the 5km and the Kids Dash has been extended to 31 October 2026 at 11.59pm, or until the field fills, whichever comes first.

Entry Fees: No Early-Bird Pricing This Year

Good news if you tend to sign up late: there is no tiered pricing this year, so the fee stays the same for the whole registration period. Here is what the organiser charges, in Singapore dollars:

The Kids Dash is $50 for the 600m, $55 for the 1.6km and $60 for the competitive 1.6km. The Crew Challenge is listed at $752 and is sold out.

Refunds and Transfers: Be Sure Before You Pay

Entries are non-refundable, cannot be deferred and cannot be transferred. If you get injured, you cannot pass your bib to a friend or roll it over to next year.

The only way out is RunFlex, an optional add-on sold only at registration, so you cannot add it later. If you buy it, you can cancel by 27 November 2026 and get 80% of your fee back, not counting the cost of RunFlex itself.

What Has Changed Since the Standard Chartered Years

• Three Days Instead of Two: The 2025 race was held over two days. In 2026 the half marathon has Saturday morning to itself and the marathon has Sunday morning.
• Fewer Places: The 52,000 cap is lower than 2025's turnout, when more than 55,000 people took part.
• Standard Chartered Stays On: It continues as the official bank partner, and its name is on the 10km.
• No More Mileage Clubs: If you were counting your kilometres towards the 300KM Club or the 500KM VIP Programme, that is over: with the change of event promoter, cumulative mileage is no longer tracked, and both have been discontinued.
• Free Early Trains on Marathon Morning: More on that below.

Getting to the Start Line: Free Early Trains on Marathon Morning

With a 4.30am flag-off, getting to the start is half the battle. Here is how the trains work on race morning:

• Early Service: On Sunday 6 December 2026, selected sections of the North-South, East-West and Circle Lines open early, with trains from 2.30am every 15 minutes.
• Free Rides: Rides are free for everyone during that window, runners and supporters alike, and you do not need to tap in, because the gantries at those stations are left open.
• Last Free Trains: The last free trains leave Bukit Batok, Jurong East, Tanah Merah and Serangoon at 4.30am.
• Check Your Station: Not every station opens early, so check the organiser's station list before you plan your route.

Running the half on Saturday? The early trains are for Sunday only. Half marathon runners get paid shuttle buses to the start instead, with details still to be announced.

Heat and Haze: Train for the Conditions

The organiser itself calls this a race where heat and humidity test endurance, so train for the conditions as well as the distance. This year there is haze to think about too—on 17 October 2026 it had already cancelled the Great Eastern Women's Run. Keep an eye on the organiser's channels in race week.
