Dear orienteering friends,

we are glad to inform you that our competition South East European Orienteering Championships and 5 days Zagreb Open will be organized on 25th to 29th of August this year. As most of multi day competitions this year are cancelled we are keen to give it a try and to see you in large numbers in Croatia.

Preliminary Bulletin is online. More updates are due to come, especially regarding accommodation. We are working on hotel arrangements, camping and dorm possibilities.

You are welcome to share the news.


If you need any additional information do not hesitate to ask us.

Good news are coming from different parts of Europe and we can expect free entry to Croatia for all visitors having “Covid” passport, test, proof of vaccination or overcoming the COVID-19 infection.
From today all visitors from Austria do not have to go to quarantine after visiting Croatia. In next few days hopefully most of the Europe will have free traveling with above mentioned papers. This means that we will probably also get a green light for a race with some smaller restrictions (no big ceremonies, parties etc.). It will mean pure orienteering 😉
We moved the entry dates a little bit later so take you chance for cheaper entry fee. Entries for the competition can be done via OOnline platform.
We opened entries on IOF Eventor for W and M 21E classes which are WRE Events on sprint, middle and long distance. Please do not forget to make your entry for MW21E classes through Eventor system.
