Frequently asked questions
Is the La Grande Course — Relais à 3 GPX available?
Yes. The track and its profile can be viewed here, and the file is available as a free download from this page.
Do these details replace the organiser's instructions?
No. This page makes sources easier to consult and separates published data from GPX calculations. Check the latest official instructions before the start.

Differences and information still uncertain
These items are shown explicitly so an approximation is never presented as official data.
Organiser distances and elevation figures are indicative; the rules state that some private or dangerous sections are not necessarily included in the public GPX. Race-day course marking takes priority.
The initial PDF regulations still describe 64 km/3,100 m D+, a 5:00 start and later cutoffs. The current operational pages and the GPX linked by the organiser use 59 km/2,800 m D+, a 4:00 start and the cutoffs included in this listing.
The full relay listing uses the complete GPX officially linked; the three sections are also kept separately, without artificial merging.
