Kaarinan Syysmaraton 2026

The Kaarina Autumn Marathon is a Finnish running event held in Kaarina and Piikkiö, centered on a flat 10.5-kilometer loop. Participants can select the marathon, half marathon, or 10 km distance, all of which are officially measured. The event also includes short races for children, with the youngest participants covering approximately 150 meters and older children running about 500 meters. The loop structure means the marathon consists of four laps, the half marathon uses two laps, and the 10 km is run over a single lap. The children's race is free and does not require pre-registration, allowing families to participate with minimal planning. A runner's account from the event characterized it as a calm yet competitive marathon environment, suitable for personal-best attempts on the flat course, though the race demands perseverance past the 30 km mark.
