The organiser will have put a lot of time into designing it.
I don't care. If it's a too much hurtle to them, then do not organize an event. It's simple as that.
it’s their responsibility to ensure they pass through the controls as prescribed.
They are not prescribing the locations properly. Having it hidden somewhere in the 321432.th turn instruction on a 8 page long PDF. That is not appropriate . A GPS coordinate looks like this: 51.3423 -1.59701
You don't have scroll through 8 pages, and there is no chance of missing one. Also in the PDF the search function is disabled, so if you miss one, you are not getting the event validated. I'm not a secretary to scroll through 8 pages, and pay 18 quid to Audax uk,and another 10-20 quid to the organizer.
We are in 2022, so getting a GPS coordinate out is 2 clicks using Google Maps.
