Istanbul Marathon

Istanbul, Turkey · First Sunday of November

The world's only intercontinental marathon starts on the Asian side of Istanbul (Altunizade, 52 m) and crosses the Bosphorus on the 15 July Martyrs Bridge — the only day civilians can traverse it on foot. The bridge apex at 88 m delivers a bucket-list panorama and the race's steepest climb. What follows is 30 km of flat Marmara coastline past Dolmabahçe Palace and the Galata Bridge before a surprise 32-metre climb through Gülhane Park finishes beside the Blue Mosque at Sultanahmet. World Athletics Gold Label race since 2012.
