10th Authentic Phidippides Run 2026 - Athens - Sparta - Athens 485km

The Authentic Phidippides Run is a 485.3 km road ultramarathon in Greece, following an Athens-Sparta-Athens route. It takes place in November; the listed edition is the 10th, marking it as a niche long-distance event rather than a standard city marathon. The course concept is straightforward and its scale is brutal: runners travel from Athens to Sparta and then return to Athens on roads. The name references Pheidippides, the ancient Greek messenger associated with the Athens-Sparta journey, providing the race its identity more than any modern city circuit could.
