What is in the file?
A route file for preparation and navigation
The GPX metadata states 165 kilometres and 8,900 metres of climbing, with the start in Auron on 25 September 2026 at 13:00 and the finish in Nice.
Distance and elevation can look different after import. Watches and route planners often recalculate the track using their own elevation and distance models. Use the official headline figures for race communication and the GPX mainly to study the shape and location of the course.

How to use the GPX

Distance and elevation
Why your watch may not show exactly 165 km
The GPX metadata contains the official headline figures of 165 km and 8,900 m of climbing. The track itself contains thousands of points, and software may calculate a slightly different total from them.
That is normal: point filtering, map matching, elevation correction and platform algorithms can all change the displayed totals. For cut-offs and official communication, the organiser’s published figures remain the reference.
Important on race day
Not a replacement for the official course information
Verify the final route before you travel.
During the race, follow the organiser’s markings and any last-minute course changes. A downloaded GPX can become outdated as soon as the route is adjusted.
