Registration for the Singapore International Marathon 2026 closes on 30 September 2026 at 11.59pm, or earlier if the race hits capacity. This is the 44th edition, and it arrives with a different name on the finisher tee. The event is now the BYD Singapore International Marathon presented by adidas, delivered by a new organiser, SG International Marathon Pte Ltd. Race weekend runs from 4 to 6 December 2026.
Standard Chartered has not walked away. The bank now backs the 10km race rather than the entire weekend, which is why hunting for “SCSM 2026” drops you on a website you may not recognise. Sport Singapore, the Singapore Tourism Board and Singapore Athletics all sit behind the event, and it keeps its World Athletics Gold Label, the only one in Southeast Asia.
Singapore International Marathon 2026 Dates, Distances And Flag-Off Times
Every race starts at the F1 Pit Building and finishes inside the National Stadium. The two shorter races are night runs on the Friday, which is a genuinely different experience from the usual pre-dawn slog.
- BYD Marathon, 42.195km, Sunday 6 December, flag-off 4.30am, cut-off 7 hours, minimum age 18
- adidas Half Marathon, 21.0975km, Saturday 5 December, flag-off 4.30am, cut-off 3 hours 45 minutes, minimum age 16
- Standard Chartered 10km, Friday 4 December, flag-off 8.30pm, cut-off 2 hours 30 minutes, minimum age 13
- 5km, Friday 4 December, flag-off 9.30pm, cut-off 1 hour 15 minutes, minimum age 10
- Kids Dash, 600m and 1.6km, competitive and non-competitive options
Ages are counted by calendar year of birth, not by your birthday. Last year drew more than 55,000 runners, including over 14,000 from 80 countries, so the start pens are not quiet.
Entry Fees And The Discount Worth Checking
There is no tier pricing this year, so the fee you see today is the fee you pay on 30 September. Local and international rates differ by $20 across the main distances.
- BYD Marathon: $188 local, $208 international
- adidas Half Marathon: $168 local, $188 international
- Standard Chartered 10km: $130 local, $150 international
- 5km: $98 local, $118 international
- Crew Challenge: $752 per team
- Kids Dash: $50 for the 600m, $55 for the non-competitive 1.6km, $60 for the competitive 1.6km
Standard Chartered cardholders get 10% off across every category, capped at the first 8,000 registrations. Cards issued in Singapore, Malaysia, Vietnam, Indonesia, Brunei, India, Bangladesh, Sri Lanka, Nepal, China, Taiwan, Korea and Hong Kong qualify. Discounts do not stack, so pick the biggest one at checkout.
The New Route Runs Further West Than You Expect
The 2026 marathon course stretches from Keppel Bay in the west out to East Coast Park in the east, taking in the Tanjong Pagar Railway Station stretch, the Singapore Art Museum, Marina Bay and the Kallang basin. It is a wider loop around the island than recent editions, and the organisers have published maps for all four distances.
The 10km is the tidier one to read. It heads from the F1 Pit Building up past Suntec City and War Memorial Park, crosses Merdeka Bridge, swings by the old Kallang Airport and finishes at the stadium. Routes are accurate as of 17 August 2026 and can still change, so check the official maps closer to the date.
Free MRT On Marathon Morning, But Only On The Sunday
This is new, and it solves the oldest problem with a 4.30am flag-off. Selected stretches of the North-South, East-West and Circle Lines will start running early on Sunday 6 December 2026.
- Trains run from 2.30am at 15-minute intervals
- Rides are free for everyone, participants and supporters alike
- Gantries at the selected stations stay open, so there is nothing to tap
- Last free trains leave Bukit Batok, Jurong East, Tanah Merah and Serangoon at 4.30am
- Only selected sections operate early, not the full network
Half marathon runners on the Saturday do not get this. They will be served by paid shuttle buses instead, with routes and ticketing released closer to race weekend. The organisers say the free MRT is a pilot with SMRT that they may extend later.
Refunds, Transfers And The Programmes That Are Gone
Read this bit before you pay, because the default position is strict. All entries are non-refundable and non-transferable, and you cannot defer to next year.
- RunFlex is an optional add-on you can only buy during registration
- With RunFlex, you may cancel by 27 November 2026 for an 80% refund, excluding the cost of RunFlex itself
- Other add-ons include the iTAB and bag deposit
- The 300KM Club and 500KM VIP Programme have been discontinued following the change in promoter, and cumulative mileage is no longer tracked
Before You Click Register
A few small things trip people up every year, and most of them are admin rather than fitness.
- Work Permit and S Pass holders whose address does not appear in Myinfo should register under the international category
- Payment is by debit or credit card only, so no PayNow
- December in Singapore is humid even at 4.30am, and the marathon cut-off is a firm 7 hours
- New to racing? The Friday night 5km is the sensible entry point, and you can always upgrade next year
- There is an official race app on both the App Store and Google Play for bib collection and results
Slots close at the end of September and the field is capped, so the practical move is to decide on a distance this month rather than in the last week. Build your training gradually and speak to a doctor first if you have any health concerns about racing in the heat. Full details, maps and FAQs sit on the official Singapore International Marathon website.
