The climbs that shape the race
The track holds 7 major climbs and 10 major descents. The biggest climb runs from km 19 to km 21: +389 m over 2.9 km at an average of 13.5%. The longest descent drops 264 m over 13.4 km from km 56 (down to Umag (Finish)), at an average of 1.6%.
Distance, total climb and high point are the organiser's. Each section's climb, descent, grade and high point, the low point and the named climbs are measured on the official GPX with the same method as the interactive profile, so the sections can add up to a slightly different total.
