About This Race
The 110K represents the full Istrian experience, demanding runners navigate the complete spectrum of technical challenges including sustained climbs through dense forests, rocky descents into ancient valleys, and the mentally demanding passages through medieval town centers. This distance requires seasoned ultrarunners comfortable with extended time on technical terrain, as the course's varied surfaces and elevation changes create a cumulative fatigue that tests both physical endurance and technical running skills over 12-15 hours. Positioned as the signature ultra distance, it offers the most comprehensive tour of Istria's landscapes while remaining accessible to runners with solid 100K experience seeking their next European ultra challenge.
