Ultramarathon of the 1944 Insurrection 2026

If you’re up for a challenge that truly means something, the 1944 Insurrection Ultramarathon in Wieliszew will give you chills from start to finish.

Here, you move to the rhythm of Masovian nature and the shimmering reflections of lakes & ponds, with that little positive tension that tells you: “OK, today I’m doing something big.” 🌿.

The 63 km format is long… but above all, it’s a chance to live a real adventure: you alternate calm stretches along the water, wilder sections, and moments when you surprise even yourself. And yes, in Wieliszew, you’ll “get wet” just enough—but always with style. 💧.

Me, as a local guide, I’ll tell you: come for the race, stay for what comes after. Once you’ve crossed the line, you can treat yourself to a great recovery with a side of exploration: a stroll along the shores of Jezioro Zegrzyńskie, a break at the harbor in Nieporęt, a detour through Legionowo to wander and grab something good to eat, or even a hop over to Warsaw to soak up the history and energy of the nearby capital 🏞️.

And if you’re coming as a duo or with family, it’s all set: a little outing on the water at Lake Zegrze, a sunset walk, then a quiet terrace to replay your day… so, ready to write your own chapter in Wieliszew? ⭐️
