adidas Stockholm Half Marathon 2026

The adidas Stockholm Half Marathon starts and finishes near the Royal Palace in Stockholm, Sweden. This 21.1 km road race crosses a capital city situated on 14 islands, featuring a medieval old town. The course guides runners past significant public structures rather than leading them to the city outskirts. The route begins at the royal castle, proceeds into the city center, moves to Kungsholmen, and then reaches Södermalm before looping back to finish before the castle. It passes Karlberg’s Castle, City Hall, the Royal Palace, the Swedish Parliament, and the Royal Opera House. While a substantial challenge, the distance is achievable for well-trained runners, making the race suitable for those seeking a demanding city half-marathon rather than solely specialists focused on personal bests.
