The organiser's 5 checkpoints split the course into 4 sections. The table gives each leg's own climb, descent, average grade and high point, measured on the official GPX.
| Section | Km | Distance | D+ | D- | Avg grade | High point |
|---|---|---|---|---|---|---|
| Start - Motovun → Livade | 0.0-5.1 | 5.1 km | +123 m | -268 m | -2.8% | 272 m |
| Livade → Grožnjan | 5.1-20.9 | 15.7 km | +724 m | -448 m | +1.7% | 380 m |
| Grožnjan → Buje | 20.9-27.8 | 7.0 km | +65 m | -180 m | -1.6% | 297 m |
| Buje → Umag (Finish) | 27.8-42.0 | 14.2 km | +95 m | -264 m | -1.2% | 215 m |
The climbs that shape the race
The track holds 4 major climbs and 6 major descents. The biggest climb runs from km 4 to km 8 (through Livade): +376 m over 3.6 km at an average of 10.1%. The steepest sustained climb averages 11.2% over 1.0 km from km 0 (from Start - Motovun), with pitches of 20.8%. The longest descent drops 98 m over 8.2 km from km 33 (down to Umag (Finish)), at an average of 1.0%.
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.
