The Cathedral course of the Alpine Gravel Challenge – Portes du Soleil is open to all and can be practiced with all types of bikes, electric or not. It is designed as a popular race with no categories or rankings, unlike the 100 and 70 km courses that offer participants in certain categories the opportunity to qualify for the 2024 Gravel World Championships.

This 30 km race aims to provide a fun and accessible experience for a wide range of participants, showcasing the region's beautiful scenery without the competitive aspect of other routes.
