Welcome to Vienna

The Vienna O Challenge launched in 2019, with the idea to create an international event open for everyone, in challenging areas, and fun to be part of. Thanks to everyone who has participated in the first five editions; 2024 already more than 340 participants from 24 countries. See you at the next Vienna O Challenge!
