The 2nd Innovation Marathon of Central Union of Greek Municipalities aims to make the digital transformation of cities known to every city and people of every age.

If you are a student and have ideas or suggestions on applications and solutions that will make your city better, we suggest you participate in the Student Contest. There, students from all over Greece will be able to submit their ideas to us. At the beginning of June, the teams selected (10 to 15 teams) will be notified to present their idea live on June 30, 2018 at the Stavros Niarchos Foundation Cultural Center. Those distinguished will receive gifts and prizes.

If you want to implement an application – MVP during the marathon and you are alone or part of a team, you can directly register to participate in the Marathon provided you can come to Athens at your own expense.

If you live near a city where a CityLab will take place, you can register to participate in the CityLab. If you qualify, we will notify you so that you can present your idea and, if you are distinguished, you will come to Athens for free to compete in the Marathon that will be held from June 28th to July 1st for prizes worth over € 20,000.
