Spartathlon for beginners: the complete guide
The Spartathlon is a 245 km ultramarathon from Athens to Sparta, run under a 36-hour overall limit with its own cut-off at each of the route’s 75 checkpoints. It has run every September since 1983 with one exception, 2020 (cancelled), inspired by the ancient messenger Pheidippides, and entry requires a recognised endurance-race qualifying performance, an application inside the International Spartathlon Association’s (ISA) deadlines and, if qualified applicants exceed 400, a lottery.
What the Spartathlon is
The Spartathlon is a 245 km ultramarathon from Athens to Sparta, run under a 36-hour time limit. The organiser’s own route description states directly that “the race is very demanding, not only because of the distance, but also for the cut-off requirements and weather conditions,” with the course climbing from sea level to 1,200 metres on Mount Parthenio.
The race revives the journey of Pheidippides, the ancient Athenian messenger who, according to Herodotus, was sent to Sparta in 490 BC before the Battle of Marathon to seek help against the Persians.
Where the idea began
The idea came from John Foden, a British RAF officer and student of ancient Greek history, who wondered whether a modern runner could actually cover the Athens-to-Sparta distance described by Herodotus within 36 hours. In the autumn of 1982 he and two RAF colleagues came to Athens and attempted the route: Foden reached the statue of Leonidas in Sparta after 36 hours, John Scholten half an hour earlier, and John McCarthy in under 40 hours. The organiser’s own historical page describes the feat as proof that “a man is really able to cover 250 km in two days” — a description of that original 1982 attempt, distinct from the race’s current official measured distance (245 km).
The success of that attempt led to the 1st International Spartathlon in 1983, with 45 runners from 11 countries plus Greece, per the organiser’s own historical page. In 1984 the International Spartathlon Association (ISA) was founded, and it has organised the race every September since, precisely because, per Herodotus’s account, Pheidippides’ mission to Sparta took place at that time of year.
The route and today’s cut-offs
The organiser’s official route description gives 245.3 km as the point where runners reach checkpoint 75 and the finish in Sparta; the same text states directly that “each of the 75 race control points has its own time limitations and should a runner arrive later than the official closing time he or she will be eliminated from the race.” The Terms of Participation document, in turn, uses the rounded figure “245 km” for the same distance.
The course runs over tarmac, dirt track and mountain footpath, with aid stations every 3 to 5 km and medical coverage throughout. Its toughest stretch is the night-time ascent and descent of Mount Parthenio, a 1,200-metre climb.
When it runs
The ISA holds the Spartathlon every September because, per the organiser’s own historical page, Pheidippides’ mission to Sparta, as recorded by Herodotus, took place at that time of year. Spartathlon 2026 runs on 26-27 September 2026, starting at 07:00 from Athens.
Who can apply
Under Chapter 1 of the official Terms of Participation, the right to take part in the Spartathlon belongs only to “experienced Athletes, that are over the age of 18,” with each participant assuming full responsibility for their own state of health before and during the race.
Chapter 2 lists specific recent endurance-performance criteria (2024-2026) an applicant must meet. Examples include finishing a 100-mile race within 21:00 hours for men or 22:00 for women, finishing a previous Spartathlon within 36:00 hours, or covering at least 180 km for men / 170 km for women in a 24-hour race — the full list of international and Greek-race criteria sits in the official Terms of Participation. The qualifying performance must have been published officially online and achieved in a race with at least 5 finishers.
How selection works when applications exceed the cap
If the total number of athletes meeting the criteria does not exceed 400, all of them are accepted. If it does, automatic priority rules apply before any lottery: athletes performing at least 25% better than a criterion, the first male and female finishers of the previous Spartathlon, athletes with at least 10 prior Spartathlon finishes (veterans), and the sole applicant from a given country are all automatically qualified.
The remaining places up to 400 are filled by lottery, which then continues to build the waiting list. Athletes who applied in 2025 and were left on the waiting list without being drawn get a double entry in this year’s lottery.
2026 registration timeline and the medical certificate
Per the official Terms of Participation: applications are accepted from 25 January to 25 February 2026 (Chapter 4). Accepted athletes must submit the ENTRY FORM by 15 May 2026 at the latest, and the participation fee must be paid by 10 June 2026 (Chapter 5).
Chapter 10 makes a medical certificate a condition of entry: it must be dated after 1 July 2026, carry a doctor’s name and seal, a date, and a statement that the athlete is fit to take part in the “SPARTATHLON 245 km distance race.” Without it, the athlete is not admitted to the race.

Frequently asked questions
How far is the Spartathlon?
245 km from Athens to Sparta (245.3 km exactly, to checkpoint 75 / the finish), per the organiser’s official route description.
What is the time limit, and what does “checkpoint” mean here?
The overall limit is 36 hours, but the official route description states that each of the 75 checkpoints has its own time limit; arriving later than a checkpoint’s official closing time means elimination from the race.
Who can apply to run it?
Athletes over 18 who meet one of the recent endurance-performance criteria in Chapter 2 of the official Terms of Participation (e.g. a 100-mile finish within 21:00-22:00 hours, or a previous Spartathlon finish within 36:00 hours), achieved in a race with at least 5 finishers and published online.
What happens if qualified applicants exceed 400?
Automatic priority rules apply first (25%-better performances, the previous edition’s winners, veterans with 10+ finishes, a country’s sole applicant); the remaining places up to 400 are filled by lottery, which continues to build the waiting list.
When does the Spartathlon run each year?
Every September, because — per the organiser’s own historical page — Pheidippides’ mission to Sparta took place at that time of year. In 2026 it runs on 26-27 September, starting at 07:00.
Do I need a medical certificate?
Yes. Chapter 10 of the Terms of Participation makes it a condition of entry: it must be dated after 1 July 2026, carry a doctor’s name and seal, and state the athlete is fit for the 245 km race. Without it, entry is not permitted.
What is the story behind the race?
Briton John Foden wondered whether Herodotus’s account of Pheidippides held up, and in 1982 ran the route with two RAF colleagues. Their success led to the 1st International Spartathlon in 1983 (45 runners, from 11 countries plus Greece) and the founding of the ISA in 1984.
