Istria by UTMB

Istria by UTMB started in 2013 and has grown into a major trail running event that brings together more than 3,000 runners from around the world. The race showcases many different sides of Istria through courses that combine difficult and technical terrain with coastal elements, old medieval towns, deep forests, city centres, muddy trails, streams and brooks, canyons, and numerous panoramic views. Its character comes from the variety of landscapes and surfaces encountered along the way, offering runners an immersive journey through the region rather than a single-style trail experience. The event is presented as part of the UTMB World Series environment, with race pages and community updates connected through the official UTMB platform.
