The Spetses Marathon (Spetses mini Marathon) is a 3 km and 5 km sea swim between the island of Costa and Spetses in Greece in October. The Spetses mini Marathon is the largest multi-sport event in Greece since 2011, including more than 10,000 participants, held in the picturesque island of Spetses, only 2.5 away hours from Athens and El. Venizelos Airport. It includes two sea swims, organized by Achilleas Tsimpogiannis. Chris Sifleet and Greek triathlon coach Armandos Linardos offer stroke analysis and nutritional advice for a week-long clinic on Spetses before the Spetses Marathon Swim.
