Istria 100 by UTMB

The 168K course is the hardest and the most beautiful course that we offer. It stretches from the eastern part of Istria, over its highest mountain down to the mainland, and ends on the western part of the peninsula in the city of Umag. Along the route, you will experience every possible aspect of trail running – really technical terrain, a little bit of coastering, old medieval towns, deep forests, city centers, old train route, muddy valleys, all spiced up with breathtaking panoramas. The course starts in the 3000 years old town Labin, climbs the Učka mountain with the spectacular views to Kvarner region and descends in Buzet where your drop bag will wait for you. After the well-deserved rest, the trail leads you into mainland, filled with small medieval towns such as Motovun – the Istrian pearl and back to the finish in Umag.

The second largest course starts from Buzet and offers you typical istrian inland trails. After first 20 km, the 110K trail merges with 168K trail and continues the climb to the highest peaks of Istria. As for the terrain, the part that leads to Buzet is very rocky and demanding, but it gets easier towards the finish in Umag. While 110 km with +4.074 m probably doesn’t sound very demanding, it is nevertheless very challenging.

This trail will show you Central Istria in all its glory! Although arduous, it is a great option for participants that are a bit less experienced in trail races. However, it still offers an opportunity to experience all the aspects of trail running – strenuous climbs, steep slopes, crossing creeks, as well as muddy and rocky terrain. At the same time, it leads through the beautiful medieval towns of Motovun, Oprtalj, Završje, and Grožnjan. The trail starts in the old town of Buzet and takes the shortest route to Butoniga lake, and it finish in the city of Umag. As for the terrain, expect large stretches of softer surfaces, combined with the all-present Istrian rock. The 69 km long trail with the climb of +2.331 m is an excellent start for participants who would like to try 168K or 110K course next time.

This course is dedicated to beginners in trail running. It starts at the bottom of the town of Motovun, climbs up the town, and merges with the other courses. With the elevation difference of 1153+ m and a time limit of 8 hours, this trail is not very challenging, but nevertheless, has all the elements of a real trail race: it leads you through steep climbs and slopes, wide paths, intact single tracks and charming hill towns – a real treat!

The race is intended for beginners in trail running, volunteers and accompanying runners who race over longer distances. The race starts in medieval Grožnjan and follows an easy path all the way to the sea, to the finish on the main square in Umag. With an elevation of 157+ m and thus a limit of 4 hours, the trail is runnable and not demanding.
