Swider Ultra River Race returns for its jubilee tenth edition on January 23, 2027, celebrating the spirit of running alongside the Swider river. This year’s theme is about embracing the wild and untamed nature of the waterway as runners explore new stretches upstream. The event offers four unique distances that cater to various levels of adventure and endurance: - The Ultra Świderiada (50+ km) for those craving more than a typical race, offering over 50 kilometers of winding river paths. - Grubo Prześwidrowany (35+ km), providing runners with an extensive dose of scenic twists along the Swider's banks and wild trails. - A shorter yet challenging distance at 24+ km, allowing participants to immerse themselves in the natural beauty while enjoying a more manageable course. The race promises exceptional scenery as competitors navigate through untouched landscapes, encountering numerous river bends that add character to each mile. The atmosphere is one of camaraderie and celebration, with organizers hinting at an exciting new addition: another waterway known ironically as Piaseczna River, which will enhance the experience for returning enthusiasts. Join this unique event where running transforms into a philosophy centered around fun, health, and personal enjoyment without pressure to compete or prove anything. Experience the magic of Swider Ultra River Race on its special anniversary day! The race is not just about crossing the finish line; it's an immersive journey through nature’s beauty and challenges along the ever-inviting Swider river.
