The climbs that shape the race

The track holds no major climb and 2 major descents. The longest descent drops 118 m over 5.2 km from km 7 (down to Thaugland), at an average of 1.7%.

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.
