Open-water swimming races in Greece in 2026
Greece does not have one public database covering every federation and mass-participation open-water race. This guide combines selected events with accessible primary sources, without claiming completeness or turning unverified fields into facts.
Selected September events
Dates and distances are a source snapshot from 31 August. The newest official announcement for each event takes priority.
- 5 September — Alonissos Challenge: Junior 150 m and Golden & Silver Swim with an unresolved distance conflict
- 13 September — Serifos Sunset Race: 750 m, 1,500 m and 3,000 m, plus children’s races
- 25–27 September — Hellenic Swimming Federation National Masters Championship: location still marked as awaited
- 27 September — GO Milina–Alatas: 1.5 km, 3 km and 8.5 km

Federation and mass-participation are different feeds
The Hellenic Swimming Federation agenda is the source for federation events. Independent open-water events require checks on each organiser’s official page.
A location marked as awaited is not filled through inference. An event without an accessible primary source is not presented as confirmed.
What to check before entering
- Live registration status
- Final start times and athlete instructions
- Any date or location change
- Participation terms and required equipment at the official source
