Undeniably one of the more scenic running routes that you will find in Athens is Dionysiou Aeropagitou, the pedestrian street going around the Acropolis all the way to Thisseio metro station. You can even extend your workout and run along the metro tracks on Adrianou until Monastiraki and then circle back. Of course, during peak season, the street becomes crowded easily, so your best bet is to run early in the morning or late evening. Feel like pushing yourself? Combine a lap around the National Gardens before crossing the street to run on Areopagitou.
Located off the Areopagitou pedestrian road, Filopappou Hill is also an excellent running spot. Lined with trees, the routes crossing the hill include marble-paved paths (lit at night) and dirt trails. There is also a water fountain by The Pnyx, where you can catch a breath and enjoy an uninterrupted view of the majestic Acropolis.
Another hill you can run on if you want something a bit more challenging is Lycabettus Hill, which features a series of trails and offers spectacular views over the city and the sea. Try to visit it in the morning as this locale is not well lit at night. The road circling the base of the hill, which is three kilometres (1.9 miles) long, is also a sought-after location with local runners, but unless you know how to handle heavy traffic, it is best if you to stick to the hill itself.
For those staying by the Athenian Riviera, the wide promenade that sits along Poseidonos Avenue and the tram is an ideal destination for a run and features a refreshing sea breeze. The summer months may mean there is a lot of foot traffic, but you should still be able to get in a good workout. With a distance of approximatively 16 kilometres (10 miles) from Kallithea to Glyfada, the promenade is one of the best and safe running routes you will find in the city.
