Traffic police will be closing off sections of the road network in central Athens on Sunday afternoon to clear the way for participants in the 4-kilometer "Live Well" race, which kicks off at Syntagma Square at 7 p.m.
The event is open to all members of the public, whether they want to run it, walk it, or ride their bicycles.
The aim of the event is to raise awareness regarding the benefits of a healthier lifestyle, with proceeds from donations going in support of the "Filoi tou Paidiou" (Friends of the Child) charity.
Some 5,000 people participated in last year's race.
All major thoroughfares from Syntagma Square to the start of Syngrou will be closed off, including parts of Academias, Vassilissis Sofias, Vassileos Constantinou, Amalias and Vassileos Olgas.
The race will end at 9 p.m., back in Syntagma Square.
