That’s a good question.

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 30th, 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 (travel and accommodation costs will be covered) to compete in the Marathon that will be held from June 28th to July 1st for prizes worth over € 20,000.

The involvement of local communities is of great importance. If you represent or work in a Municipality or another organization of your city, you can help bring the digital transformation to your city.

  • You can record ideas, problems or issues that you would like to see addressed by the applications to be created during the Marathon through a Consultation.
  • You can help by promoting the event in local communities and groups of students, professionals etc. that may be interested in participating.
  • You can participate in the event as a mentor or volunteer.

If a CityLab is to be held in your city, please contact the organizing team.

We are glad that you do.

The entire cost of the event is covered by Central Union of Greek Municipalities and the sponsors, as the participation of all contestants is FREE.

If you are interested in participating in the event and supporting by providing money or services in kind, please contact the organizing team.
