Spetsathlon
Spetsathlon — Greece's largest triathlon weekend — returns to car-free Spetses in mid-May 2027, with open-water swims off Agios Mamas, a circuit of the island by bicycle and the Sunday triathlons from Poseidonion Square.
Spetsathlon is an annual multi-sport event held on Spetses in the Saronic Gulf, described by its organisers as the largest triathlon held in Greece. The event was launched in 2013 under the presidency of Marina Koutarelli, who had founded the Spetses Mini Marathon two years earlier. The weekend runs almost entirely from Poseidonion Square at Dapia on the car-free island; Spetses has restricted private cars from its lanes since the early 1960s. The 2027 edition is scheduled for mid-May; the exact dates are to be confirmed by the organisers.
Saturday comprises the standalone disciplines: open-water swims of one and three kilometres off Agios Mamas beach, a twenty-five-kilometre cycle around the island, and a five-kilometre run in the late afternoon. Sunday morning holds the two triathlons from Poseidonion Square: the Sprint over 750 metres of swimming, twenty-five kilometres of cycling and five kilometres of running, and the Endurance over its Olympic-plus distances of 1.5 kilometres of swimming, fifty kilometres of cycling and ten kilometres of running.
