The climbs that shape the race
The track holds 4 major climbs and one major descent. The biggest climb runs from km 0 to km 11 (from Start - Sierre): +1,501 m over 10.7 km at an average of 13.8%. The longest descent drops 777 m over 8.9 km from km 22 (down to Zinal (Finish)), at an average of 8.3%.
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.
