Endurance load on ITRA's km-effort scale — not steepness or technical terrain.
How we measure
km-effort = distance + climb/100, ITRA's published scale: every 100 m of climb counts like ~1 km of distance. Six levels, Easy → Brutal, from the hardest distance of the event. The climb figure (m/km) shows how vertical the course is.Drive

Our take
The catch · Our read
166 km-esforç, 26h cutoff, overnight cold at altitude — this is a genuine mountain ultra, not a "trail"
Who it's for · Our read
experienced ultra runners with high-mountain nav and cold-weather kit. Not for first-timers
Also nice · Our read
alpine grandeur, sold-out prestige, Salomon production values
In a word · Our read
Catalonia's answer to a UTMB-circuit 100 — harder than the "100 km" label alone; the 6600 D+ is the real story
