Half marathons in Greece 2026–2027: the complete guide
As of 29 September 2026, the day of the source check, the bib2bib catalog shows 25 upcoming half marathons (about 21.1K, discipline “road”) in Greece, running from 4 October 2026 through 16 October 2027, each with an official or verified source. Earlier in 2026 (August-September) the catalog's other half marathons already took place — they are not shown here, since this year's edition of each has already happened. Three further entries with “half marathon” in their name are left out of this list, each for its own reason: the Freedom Run from Thermopylae to Gorgopotamos, which will not take place in 2026 per the organiser's own cancellation notice (no return date announced); the Kremasta Lake Run - Acheloos Half Marathon, whose longest catalog distance is 25K, not 21.1K; and the Lefkas Fun Run Half Marathon, which has no official link yet and stays non-indexable. Every race below links to its official page, as confirmed during the source check on 28-29 September 2026.
What a half marathon is, and how many are still ahead in Greece this cycle
A half marathon is a 21.0975K (21.1K, 13.1094-mile) road race — exactly half the marathon distance (42.195K), per Wikipedia. In Greece the distance is usually published as “21 km” or “21.1 km” in race announcements, while a few events publish the exact figure (e.g. 21.096 or 21.097 km).
As of 29 September 2026, the day of the source check, the bib2bib catalog shows 25 upcoming half marathons in Greece (discipline “road”, excluding Cyprus), from standalone half marathons to city races where the half marathon is the longest of several distances on offer. All of them carry an official link or a verified source, so all are indexable on bib2bib. Earlier in 2026 (August-September) another 11 half marathons in the catalog already took place; they are not listed below, since this year's edition of each has already happened.
- October 2026: 17 races — the busiest month
- November-December 2026: 3 races
- Spring-autumn 2027: 5 races
October 2026 (1-11): the busiest stretch
October is the busiest month in the catalog for half marathons, with 17 events inside the month. The first eleven days alone account for 12 of them, peaking on Sunday, 4 October, when seven half marathons run at the same time in seven different cities. (The Freedom Run from Thermopylae to Gorgopotamos was also scheduled for 11 October, but the organiser has announced it will not take place in 2026 — see below.)

Greece's most international half marathons
Four events in the catalog explicitly claim an international profile, in their name or on their official site. The 18th International Poseidon Athens Half Marathon, run along the seafront at Faliro Bay, describes itself on its official site as open to “athletes of Greek or other nationality” and features testimonials from foreign runners. The 5th International Patras Half Marathon also brands itself as international and cites a certified course recognised by an international body. The Crete International Half Marathon in Arkalochori and the Thessaloniki Night Half Marathon (the 2027 edition is listed on the official calendar of AIMS, the world association of marathons and distance races) round out the list.
AIMS (the Association of International Marathons and Distance Races) functions as a worldwide federation of race organisers, running its own course-measurement services and a member calendar spanning the globe — a race's listing on that calendar signals international recognition, not a guarantee of record status on its own.
Coastal, night and memorial half marathons
Beyond geography, several half marathons in the catalog stand out for their format or the occasion behind them.
- Coastal: the Tamynai Seaside Run (Euboea), Oropos Seaside Race (Attica), Thermaikos Coastal Half Marathon (Thessaloniki)
- Night races: the Patras Night Half Marathon and the Thessaloniki Night Half Marathon (14th edition, plus the 2027 listing) — both run on a Saturday evening
- Memorial/historical: the 17th Panhellenic Road Race “Lignite Memories” (Ptolemaida), the Pella Half Marathon (Giannitsa Sacrifice Run) — note: the memorial Freedom Run from Thermopylae to Gorgopotamos has been cancelled for 2026, see Practical notes below
Practical notes: how to search, and what the official page always wins on
bib2bib's own half-marathon (21K) distance filter shows every catalog entry with a value between 20.9 and 21.2K, sorted by date. This guide also includes two 2027 festivals (Thermaikos Coastal, Thessaloniki Night) whose official distance list reads only "Half marathon" with no numeric figure for that leg — bib2bib's own filter does not yet surface these two until their distance string carries a ~21.1 value. For dates, registration deadlines, entry fees and bib pickup, each race's own official page remains the only authoritative source; bib2bib does not handle registration or payments.
Three entries named “half marathon” that are left off the list above show why it always pays to check current status, not just the name: the Freedom Run from Thermopylae to Gorgopotamos was scheduled for 11 October 2026, but its organiser (Trahina) announced that “the 2026 race will not take place,” citing rising running costs, with no return date given; the Kremasta Lake Run - Acheloos Half Marathon's longest catalog distance is 25K, not 21.1K; and the Lefkas Fun Run Half Marathon has no official verification link yet and stays out of the index until it gets one.
Frequently asked questions
How many kilometres is a half marathon?
21.0975K (usually rounded to 21.1K, or called a “21K”), which is exactly half the marathon distance (42.195K), per Wikipedia.
How many half marathons are still ahead in Greece through the end of 2027?
25 upcoming ones, per the bib2bib catalog as of 29 September 2026 (discipline “road”, excluding Cyprus), each with an official or verified source; another 11 in the catalog already ran earlier in 2026 and are not included. Three further entries with “half marathon” in the name are left out — one cancelled for 2026, one with the wrong distance, one non-indexable — see above.
Which month has the most half marathons in Greece?
October, with 17 events in the catalog — more than every other month combined.
Which half marathons in Greece have an international profile?
The International Poseidon Athens Half Marathon, the International Patras Half Marathon, the Crete International Half Marathon, and the Thessaloniki Night Half Marathon (also listed on the AIMS calendar) all explicitly claim an international profile.
Is there a night half marathon in Greece?
Yes, two: the Patras Night Half Marathon “Fanis Tsimigkatos” and the Thessaloniki Night Half Marathon, both run on a Saturday evening.
What is the difference between a half marathon and a marathon?
A marathon is 42.195K; a half marathon is exactly half that, 21.0975K. Marathons in Greece are covered in a separate bib2bib guide.
Why are some races with “half marathon” in the name missing from this list?
Three such entries are left out, each for its own reason: the Freedom Run from Thermopylae to Gorgopotamos was cancelled for 2026 by its own organiser; the Kremasta Lake Run - Acheloos Half Marathon's longest recorded distance is 25K, not 21.1K; and the Lefkas Fun Run Half Marathon has no official verification link yet, so it stays non-indexable.
How do I find the right half marathon for me?
Use bib2bib's half-marathon (21K) distance filter to see every entry sorted by date, and compare city, month and race type (coastal, night, city) yourself.
