Time Estimates
This climb begins in the French commune of Isola in the Alpes-Maritimes department in southeastern France and takes riders to the Isola 2000 Alpine ski resort.
The climb’s inclusion as the finish of stage 19 in the 2024 Tour de France marks only the second time it has been included in the Tour. (The first was in 1993, when Toni Rominger outsprinted Miguel Indurain in a two-up sprint for the win.)
Featuring 35 switchbacks, this is perhaps the twistiest climb in Zwift’s Climb Portal library!
