How we verified this.
Is Istanbul worth visiting during the Istanbul Marathon?
Packed on the event day; the nearest calm days are Calm. our forecast
Worth it if Istanbul 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 5–7 Nov 2026 is the quieter plan. advice
Where are the crowds in Istanbul during the Istanbul Marathon?
The bridge itself is closed to vehicles for the morning, and every distance — the marathon, the shorter races and the mass run — ends near the historic core, so that is where the crowd lands: runners and walkers all pouring into the same streets by the monuments.
Road closures: what closes and when the streets reopen
The Bosphorus Bridge is closed to vehicles for the morning of the race. The organiser publishes the routes for each distance and the closures on its own site; check them before planning any crossing that morning — the ferries are the way over the water.
Times and routes change: maraton.istanbul 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.
