Kladno Marathon

25. Kladenský maratón is a traditional “runners for runners” event hosted at the Kladno City Athletics Stadium and set for Saturday, September 19, 2026 (start 10:00). The race combines a classic stadium start/finish with a loop course through Lapák forest park, creating a friendly but serious marathon setting that’s well organized, easy to follow for spectators and built for steady pacing.

The marathon begins on the track and continues with 8 laps on asphalt and compacted park paths before returning to the stadium track for the finish. The time limit is 6 hours, and aid stations are provided every 5 km plus refreshments at the finish. Facilities on site include changing rooms and showers, with race-day registration/check-in available in the morning at the stadium grandstand.

Beyond the main marathon, runners can choose:

• Relay for 2–4 runners (mixed, no age/gender limits)

• 6 km side race (start 11:00) with the same support and service standards as the marathon

The event also serves as a key competition for experienced athletes, including regional and masters championship classifications, with cash prizes, trophies and bonus rewards for breaking the course records. Participation is open to runners 18+ and awards are scheduled for 14:30.
