Cool start — fast day potential

A cool 49°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Light winds shouldn't be a major factor for pacing. High humidity (83%) will make it harder to cool down through sweat — increase fluid intake accordingly.

About the Istanbul 10K

The Istanbul 10K is the shorter race of half marathon weekend, run on the same Sunday morning through the Historic Peninsula. It starts and finishes at the Yenikapi Event Area in Fatih, beside the Marmaray and metro station, and stays on flat streets along the Marmara coast. The roads are closed to traffic, so the course is open and fast.
