2026 Warsaw Marathon - Sep 27 Countdown

Q: How do I register for the Warsaw Marathon 2026?

Registration is first-come, first-served through the official portal at rejestracja.maratonwarszawski.com &mdash; there is no lottery. The marathon field is capped at 14,000 entrants, and it historically fills before race day, so register early. Note that the Warsaw Half Marathon is a separate event held in March, not part of the September marathon weekend.

Q: How much does the Warsaw Marathon cost?

The full marathon entry is date-tiered: roughly 210 PLN in late 2025, 260 PLN through March 2026, 310 PLN through August, then 360&ndash;410 PLN in the final weeks. International runners can also use a dedicated EUR tier (~&euro;60&ndash;120). Earlier you sign up, the more you save.

Q: Is the Warsaw Marathon course flat?

Yes &mdash; it is one of the flattest big-city marathons in Central Europe, with only about 90 m of total elevation gain over 42.195 km. The single city loop has no significant climbs, which is why it markets itself as a personal-record course.

Q: Is the Warsaw Marathon a Boston qualifier?

Yes. The course is certified by both the Polish Athletic Association (PZLA) and World Athletics, so a finish time counts toward Boston Marathon qualifying and other races requiring a certified result. No qualifying time is needed to enter Warsaw itself.

Q: What is the time limit for the Warsaw Marathon?

The overall cutoff is 6 hours 30 minutes from the starter's gun (about 9:15 per km). There are intermediate checkpoints: 3:15 at halfway, 4:45 at 30 km, 5:30 at 35 km, and 6:15 at 40 km. Runners off these splits may be asked to move to the sidewalk.

Q: What is the weather like for the Warsaw Marathon?

The late-September race day is typically cool and dry: around 14&deg;C (57&deg;F) at the 9:00 a.m. start, climbing to the mid-teens by midday, with humidity near 71% and only a ~19% chance of rain. These are near-perfect marathon conditions.

Q: How big is the Warsaw Marathon?

It is the largest marathon in Poland. The 2025 (47th) edition drew a record field of over 11,500 marathon starters and about 9,500 finishers &mdash; the largest full-marathon field in Polish athletics history. (The marathon entry cap is 14,000; the 11,500 starters and 9,500 finishers reflect the actual 2025 turnout, which ran below that cap.)

Wind Impact on Race Day

Wind at 20.4 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.
