Autumn–winter races in Greece: Oct 2026 to Feb 2027

A five-month season: what the bib2bib catalog shows

The bib2bib catalog is not static — it is continuously updated, and every listing carries a source and a last-checked date. In the 29 September 2026 snapshot, the 197 verified races between October 2026 and February 2027 are spread very unevenly across the five months.

• October 2026: 131 races — the busiest period of the year
• November 2026: 45 races — headlined by the Athens Marathon
• December 2026: 14 races — the shift into winter
• January 2027: 5 races — the second-quietest stretch
• February 2027: 2 races — trail in Attica and Crete

October 2026: the busiest period of the year

October accounts for nearly two-thirds of the whole catalog, across almost every sport at once: road, trail, triathlon/aquathlon, cycling and open water. A selection, not the full list:

• Spetses mini Marathon — 3–4 October 2026, Spetses — 5/10/25 km road races and 1.5/3 km open-water swims as separate catalog entries; the official programme page and the swimming-races page disagree on the date of the 3 km swim, a discrepancy noted on the race page
• Run Greece 2026 – Piraeus — 4 October 2026, Piraeus — 5/10 km
• 18th Greece Race for the Cure® — 4 October 2026, Pedion tou Areos, Athens — 5 km race and 2 km community walk
• Patras Night Half Marathon "Fanis Tsimigkatos" — 10 October 2026, Patras — 5/21.1 km

• 12th Run of the Immortals and King Leonidas Run — 24–25 October 2026, Tripoli–Sparta(–Mystras–Kalamata) — two separate ultra-distance races (142 km and 80 km) through the Taygetus range; the Run of the Immortals is this year dedicated to the 200th anniversary of the Exodus of Messolonghi and should not be confused with the Spartathlon (Athens–Sparta), which does not fall within this catalog window

November 2026: the Athens Marathon and the autumn ultra circuit

November opens with the country's best-known road race and closes with another round of ultra-distance and multisport events.

• Athens Marathon — 8 November 2026, Athens — 42.2/10/5 km; the 43rd edition, according to the race's own official website, which also states World Athletics Road Race Label status and a new partnership with the Abbott World Marathon Majors

December 2026: the shift into winter

The race count drops sharply in December, but the quality of the lineup stays high, headlined by the Minoan Athlos in Crete.

• 24th Minoan Athlos — 6 December 2026, Phaistos to Knossos, Heraklion — 70 km run (9-hour cutoff) and a new 3x23 km relay, plus a separate 140 km cycling event on the same date and route

• 12th Run the Lake Vouliagmeni — 20 December 2026, Vouliagmeni, Attica — 1/5/10 km; the listing notes the official 2026 proclamation was still pending at the last check

January 2027: the second-quietest stretch of winter

Only five catalog races fall in January, all trail/ultra apart from the national cyclo-cross championship.

• 2nd Ermionida Cross Country Running — 9 January 2027, Ermioni, Argolida — six distances, from 1.3 to 18 km

• Kalikantzaros Trail 2027 — 31 January 2027, Serres — 8/21 km

February 2027: warming up before spring

Just two races sit in the catalog for February 2027 — both trail. It is the thinnest month of the period, and the most likely place for new listings to be added as the date approaches.

• Retzakas Trail Run — 7 February 2027, Plokamiana Inachoriou, Chania — 6.8/24.7 km
• 12th Lycabettus Run — 21 February 2027, Lycabettus, Athens — 4.5/5.5/9/11 km

Cycling, open water and swimrun across the same period

Sports are not spread evenly across the five months. Cycling (federation races, brevets, MTB) is heavy in October and November, drops to 5 listings in December (four brevet/MTB entries plus the 140 km Minoan Athlos cycling race named above), and nearly disappears after that: just one listing in January (the national cyclo-cross championship) and none in February. The catalog's open-water swims fall exclusively in October (6 listings, all by 17 October). Swimrun bridges October (Hydra) and November (Corinthia), with no further listing until February.

Triathlon/aquathlon follows a similar pattern: concentrated in October (e.g. whynot Legacy Nafplio, XTERRA Greece O.W.S. Challenge) and November (whynot Legacy Sounio, TITANES Ioannina), with no catalog listing in December, January or February within this period.

How to use this calendar on bib2bib

The list above is a selection, not the full catalog — especially for October, which holds 131 listings. For the complete list for any given month, bib2bib's own month page (e.g. bib2bib.com/races/month/2026-10 for October 2026) shows every verified event with its date, location and a link to the race page.

• Filter by month, sport, region and distance on the Races page.
• Open each race page to see its verification status and last-checked date.
• If a listing carries a notice — like Spetses mini Marathon's 3 km swim date, or Run the Lake Vouliagmeni's pending proclamation — treat it as unconfirmed until an official clarification is published.
• Always use the official outbound link before registering, booking travel or accommodation.
