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 give 7:15/7:30 and a closing time of 18:30; the current operational page uses 6:00/6:15 and 15:30.
