SantaRun 2026
The SantaRun Haarlem has become a beloved tradition. In 2025, the city center of Haarlem was the scene of many hundreds of festively costumed participants for the twelfth time.
The course of approximately three kilometers leads through the illuminated streets of the historic city center. One lap is sufficient, but enthusiastic participants are of course welcome to complete multiple laps.
It's not about the fastest time. It's about fun, connection, and doing something good for the city together.
Why participate?
For the good cause
The proceeds from the SantaRun Haarlem go to local initiatives committed to combating child poverty. This way, the impact remains close by and visible.
For everyone
Running is not mandatory. You can run, walk, roll, or skip. Young and old participate in their own way.
For the atmosphere
Christmas music, a joint warm-up, special outfits, an outdoor bar, and a festive Grote Markt make the SantaRun a complete night out.
Put on your best Christmas outfit
Come as Santa Claus, Mrs. Claus, Christmas angel, reindeer, snowman, or in your own eye-catching Christmas creation.
The best and most original outfits stand a chance to win a prize. Participating alone is already festive, but doing it with friends, family, colleagues, or teammates makes it even more fun.
Friday, December 18, 2026 Grote Markt Haarlem Program from 18:30 Start at 19:30
