Patras's Saturday-night half marathon: 21.1 flat kilometres along the seafront of Greece's third city, from the old port past the marina and Terpsithea to the Agyia marsh, with the Rio–Antirrio bridge ahead of you. The gun goes at 18:15, the sun sets behind the gulf within the first hour, and the city runs its waterfront in the dark. A certified course, named after the Patras marathoner Fanis Tsimigkatos.
