The paved island route follows rolling coastal and interior roads around Büyükada. Hills and frequent changes in direction make it more challenging than a flat city course.

Race-day weather

Late September around Istanbul is often warm and sunny, with moderate humidity and a chance of wind from the Sea of Marmara. Shade varies around the island.
