I’m confused as to why we seem to need mandatory calendar events.
Is the aim to check calendar event completion by GPS?
if so you don’t need manned or ‘receipt’ controls.....
Just set control points that everyone must ride through, just like DIYxGPS, but leave the rest of the route flexible to the individual’s choice.
If it’s really to avoid info controls on a calendar you can just set extra control points at the info positions, check the GPS, and of course you also won’t need volunteers at the normal control points.
If an organisers routes were already long enough with the controls and infos, why go mandatory - let’s just allow GPS monitoring for all.
Mind you there are many non GPS riders out there, and if organisers are going purely mandatory, how can a non GPS rider prove completion of the full mandatory route ?
Mandatory calendar events would actually seem to discriminate against non GPS riders....
Maybe mandatory calendars are just to save the organisers doing any organising apart from route, start and arrivee ?
