A new semi- marathon race, the Poseidon Challenge, will be held for the first time on October 2 at the southest part of Attica, at Sounio Cape. The race will link the Temple of Poseidon with the ancient theatre of Thoricus near Lavrio, the most ancient theatre in Greece.

To commemorate Sunday's full moon, numerous Greek archaeological sites and museums will be open to the public with free admission.

The National Technical University of Athens (NTUA) has collaborated with the Attica Regional Authority to turn old railroad tracks into bicycle lanes, according to reports.
