If you are crossing the Historic Peninsula by road this morning, plan around the Istanbul'u Koşuyorum European Stage. The race starts beside the Langa bus stop in front of Yenikapı Miting Alanı and uses the Kennedy Avenue coastal corridor towards Kumkapı and Cankurtaran before returning to Yenikapı.
The useful traveller takeaway is simple: this is a short-lived but important Sunday-morning road disruption on a route that matters for taxis, airport transfers, private cars and cross-city driving near the south edge of the Historic Peninsula. Rail and Marmaray access to Yenikapı remain the more predictable choice for race participants, while drivers should use the official alternatives rather than trying to edge along the closed seafront.

1. What is closed on 4 October?
Istanbul Metropolitan Municipality's Transport Management Center says the seaside road is closed because of the Istanbul'u Koşuyorum – European Stage. A separate traffic notice lists the core closure on Kennedy Avenue between the Samatya Varyant area and Sirkeci Square, together with Langa Bostanları Street, Namık Kemal Avenue and selected Eurasia Tunnel exit connections towards Aksaray.
The race organiser's programme gives the practical closure window as 06:00–12:00. That means the biggest transport effect is concentrated in the morning, but traffic queues can take time to clear after barriers are removed. If you have a flight, ferry, intercity connection or fixed reservation, build in more margin than you would on an ordinary Sunday.
2. Race route and timing
The official event page places the start at the Langa bus stop in front of Yenikapı Miting Alanı. The race heads east along the coast on Kennedy Avenue, passing Kumkapı and Cankurtaran. The 5K description turns near Çatladıkapı Social Facilities and returns to Yenikapı on the same coastal road.
The event programme starts admitting participants from 07:15. The 5K warm-up is 07:40–07:50 and the race starts at 08:00. The 10K warm-up is 08:50–09:00 and the 10K starts at 09:15. The awards ceremony is listed for 11:00 and the event closes at 11:30.
For non-runners, those timings explain why a road can still be closed after the early field has passed. Do not assume a clear-looking stretch is open to normal traffic until police and traffic teams remove the controls.
3. What are the driving alternatives?
Traffic guidance published ahead of the event points drivers towards alternatives including the Eurasia Tunnel transit route, Vatan Avenue, Millet Avenue, Onuncu Yıl Avenue, Reşadiye Avenue, Ankara Avenue and Kadırga Limanı Avenue, depending on origin and destination.
That list is not a promise that every alternative will be quiet. When Kennedy Avenue closes, traffic is redistributed into other Historic Peninsula approaches. Use live navigation before leaving, and if your trip can be made by rail, metro or tram, public transport may be more reliable than trying to find a vehicle route around the event.
4. What should Istanbul visitors do?
Staying in Sultanahmet or Sirkeci: avoid planning a taxi journey that depends on a clean run along the southern seafront during the closure window. Tram, Marmaray and metro connections are less exposed to the road race.
Heading to or from an airport: the race does not close Istanbul's airports, but road access across the city can be slower where traffic is diverted. Leave extra time and rely on your live route rather than a saved estimate from the night before.
Visiting Yenikapı, Kumkapı or Cankurtaran: expect barriers, race activity and pedestrian movement around the coastal corridor. The disruption is useful to know about even if you are walking, because taxi pickup points and bus stopping patterns can shift temporarily.
5. Getting to the race
The organiser specifically recommends Marmaray Yenikapı Station for access to the start area. That is the simplest advice to follow because it avoids the same road network being closed for the race.
Both the 5K and 10K categories are shown as full on the official event page, so this is not a last-minute registration alert. It is primarily a race-day logistics and traffic update for people already entered, spectators, residents and visitors moving through the area.

Recheck before driving: temporary traffic controls can change in real time. Follow police, municipal and live-navigation instructions on the ground.
