On 8th of December , 2019, thousands of costumed runners and walkers – elves, Santa Clauses and other imaginative characters – ran and walked for the fourth year in a row in the heart of Zagreb’s festive decorations as part of the most colorful humanitarian race, Zagreb Advent Run. The central and only sporting event of the famed Zagreb Advent 2019 was held with a record number of participants – as many as 3,150 runners and walkers from 34 countries.
