Experience the beauty of Istria during spring at Istria 100, showcasing the region's stunning landscapes. This challenging 100-mile course starts in the ancient town of Labin, ascending the Učka mountain and offering breathtaking panoramas along its rugged path. Competitors will encounter a variety of terrains, including technical sections, coasteering, medieval towns, deep forests, and historic routes, ultimately finishing in the vibrant city of Umag. The elevation gain of 6,390 meters makes this course incredibly demanding, making it essential for participants to be well-prepared. For those seeking a lesser challenge, an alternate 128-km route begins with a steep ascent to Učka mountain, merging with the main trail to Umag. Though it features a rugged, rocky section, the course eases towards the end, still presenting considerable demands, especially when tackled overnight. Additionally, a 67-km trail designed for aspiring ultra runners and a less challenging course from Motovun cater to beginners, ensuring a variety of experiences while immersing in Istria's captivating landscapes.
