Aydos Ultra Trail Run

Istanbul will swap skyline for singletrack on May 3, 2026, as Aydos Ultra Trail Run takes over the pine-scented paths of Aydos Forest in Yakacık (Kartal)—a rare chance to run “in nature” without leaving the city behind. With 5K, 10K, 20K, and a 43K ultra on the menu, this event is built like a ladder: easy entry for newcomers, longer loops for seasoned trail runners, and a full ultra test for those who want the weekend to bite back.

For performance-minded runners, there’s a real competitive edge: finishers of the 20K and 43K will collect points toward ITRA rankings, adding international credibility to a course that already delivers on atmosphere. And for sports travelers (and their companions), Aydos is the sweet spot—forest air, fast access, and a race-day vibe that feels like a getaway. Even if you’re not running, you’ll still want to come along—because the sidelines are shaded, the energy is close, and Istanbul’s “green side” is a story worth seeing.
