Ston Wall Marathon

On September 21, 2025, you'll run 42.2 kilometers through Ston, Croatia on a hilly trail course that climbs 802 meters over varied terrain. The route follows the historic Ston Wall with elevation changes ranging from near sea level to 129 meters, making this a proper climbing day that demands respect for the terrain and decent downhill management. This is a trail marathon, not a road race, so expect uneven surfaces and the kind of footing that requires focus, especially in the later miles when fatigue sets in. Registration is open now, and the race is part of the Zero Waste Blue project, meaning the organizers are serious about minimizing environmental impact. Check the FAQ section on their website for specifics about start times, course measurement verification, and registration confirmation details, since the website indicates these are common questions from runners.
