ZAGREB21 – Zagreb Spring Half Marathon turns a March weekend in Croatia’s capital into a full-scale celebration of running. Built around a Saturday evening 5K and a Sunday morning half marathon plus relay, the event brings together competitive runners, recreational participants, and teams in a format that feels bigger than a single race. Start and finish are set in front of the National and University Library, creating a recognizable focal point for the whole weekend and giving the event a distinctly urban identity from the first step to the finish line. Over recent editions, ZAGREB21 has continued to grow, with the organizers calling the 2026 race the largest edition so far, while the 2025 anniversary edition welcomed around 2,000 runners from 30 countries.
What makes the race especially attractive is the combination of speed, variety, and atmosphere. The half marathon covers 21.098 km over two laps of different lengths, and race materials describe it as a flat, fast course, while external event listings note that it crosses the Sava River four times and shows runners multiple sides of Zagreb. The relay adds a strong team element, and the evening 5K helps turn the whole program into a spring running festival rather than a one-distance event. With electronic timing, refreshments, medical support, closed roads, and a route designed to showcase attractive parts of the city, ZAGREB21 offers both a serious racing setup and a memorable way to experience Zagreb in motion.
