The allXtri family consists of the Norseman Xtreme Triathlon, the CELTMAN! Extreme Scottish Triathlon and the SWISSMAN Xtreme Triathlon. These three events together are the allXtri Trilogy and support each other in friendship. Following the original idea of the Norseman, the three extreme triathlons have the same goal of being a unique race with a familiar atmosphere, offering each athlete and supporter a once in a lifetime adventure in breathtaking surroundings. It is important that each of the three triathlons represents its country well and promises the participants a difficult but beautiful journey.
