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 GPX is the full route shared by the solo and the relay; it does not separate the two legs.
