About This Event

Run through the pine-scented, car-free lanes of Büyükada, this race uses the island's quiet roads — shared with horse-drawn carriages and bicycles — as its course. Organized jointly by bro'event and the Adalar Kültür Derneği, it offers three distances from 5K to a half marathon. The island is reachable only by sea, so getting to the start means a ferry: sailings differ between operators, and the timetable is worth checking against the operator's own site when planning the trip. Entry fees rise across three windows; the normal one closes on 31 August and late entry runs to 20 September.

Frequently Asked Questions

How do I register for an event?

Registration happens on each event's own official website — RaceTurkiye links you there, but doesn't process registrations or payments itself.

Can I get a refund if I can't make it?

Refund and cancellation policies are set by each event's own organizer, not RaceTurkiye — check the event's official registration page for their specific policy.

Do I need an account to browse events?

No — you can browse and compare events without signing up. Creating an account lets you save races to a personal list under "My Account".

Are the reviews on this page verified?

Not yet — any signed-in athlete can leave a review, and we don't currently verify that reviewers actually took part in the event. That's why every review is labeled as an unverified attendee.

How accurate is the event information?

We aggregate publicly available facts (dates, distances, pricing) from each event's official source and write our own descriptions. Always confirm final details on the event's own site before registering.
