XTERRA Greece Vouliagmeni in Vouliagmeni/Athens
An off-road triathlon on the Athenian Riviera, combining open-water swimming off Vouliagmeni Beach with technical mountain biking and trail running through the South Hymettus hills, held since 2016 after the Greek edition's earlier run at Lake Plastira. Multiple distance categories, including a full-distance race, a sprint option and a children's triathlon, run across the same weekend near central Athens.
A swim in the sheltered water off Vouliagmeni Beach gives way almost immediately to steep, rocky mountain-bike single-track through the South Hymettus range, and that abrupt shift from Athenian Riviera coastline to genuine off-road terrain is the entire premise of XTERRA Greece.
