ISTRIA 100 by UTMB 110K (Istria, Croatia) 2026
Also known as: ISTRIA 110K · Istria 100 by UTMB 110K
A point-to-point from the inland town of Buzet: after about 20 km it joins the 168K route and climbs to Istria's highest peaks, returns through Buzet and heads for Umag. The rocky section to Buzet is demanding; the terrain eases toward the finish.
The course tops out at 1,017 m (low point 0 m). 5 climbs of 300 m or more keep coming; the biggest is 592 m around 0–13 km. About 50% of the distance is gentle (under 5% grade). The median finish was about 19 h, through one night.
