About
ZAGREB21 – Zagreb Spring Half Marathon takes place on 20 and 21 March 2027 in Zagreb, Croatia. Saturday closes with a 5K at 7pm. On Sunday morning at 8.30am, the 21.1 km half marathon starts alongside a relay covering the same distance in teams of four runners. All races are run on roads.
The weekend format lets runners pair a fast evening race with a half marathon the next day, or share the load within a group. With legs of just over five kilometres per runner, the relay is a friendly introduction for those not yet aiming for the full distance. For the half, a ten-week plan with a progressive long run and a weekly threshold session covers most needs, and a spring city course lends itself well to a personal best attempt.
