Ironman Costa Navarino 70.3 2026

A dirt-path run with the Ionian Sea in view distinguishes this IRONMAN 70.3 from a generic resort triathlon. The race is based in Messinia, Greece, offering a late-season half-distance IRONMAN: 70.3 miles of swimming, cycling, and running, half the original IRONMAN format. It is part of the IRONMAN Pro Series, where elite athletes compete in selected events for prize money. Costa Navarino provides a sports-resort setting for the race, featuring four 18-hole golf courses, the Mouratoglou Tennis Center, and summer camps that already attract athletes. Greece entered the IRONMAN 70.3 circuit with this event, and its first edition became the country’s largest triathlon, biggest bike race, and biggest open-water swim. The format links it to a global 70.3 calendar of over 150 races in more than 50 countries, but the local event remains closely tied to the Messinian coast and the Ionian Sea.
