Singapore's flagship running weekend in early December: a marathon and its shorter races through the civic district and around Marina Bay, with a big international field and part of the running done in the evening to dodge the heat.

Here for it?
Stay in or near the civic district so the start is a walk, and keep the evening races in mind when you plan dinner — the bay loop is the course, not the promenade, on those nights. The heat is the opponent here; the evening timings exist because of it. advice

How we verified this.
Is Singapore worth visiting during the Marathon?
Packed on all 3 event days; the nearest calm days are Lively. our forecast
Worth it if the Marathon is why you're coming — expect Packed days; if crowds are your concern, it is the one time to avoid — the calm week of 10–12 Dec 2026 is the quieter plan. advice
Where are the crowds in Singapore during the Marathon?
The races run through the civic district and around Marina Bay, so that is where the closures and the crowd sit for the weekend; the international field fills the hotels for the whole of it.
Road closures: what closes and when the streets reopen
The closures sit inside the civic district and around Marina Bay across the race weekend, some of them in the evening because part of the running happens then. The organiser publishes the routes and the closure times on its own site — check them before booking anything that needs a car in the centre that weekend.
Times and routes change: singaporeinternationalmarathon.com is the organiser's own page and the authority.
Our crowd forecast is an informed estimate, not a guarantee — check with the organiser and/or local authorities before you plan around it.
our forecast marks a number we worked out from published data; advice marks something we think. Never the other way round.
Named places appear here only after checking their own website; anything unverifiable is left out.
