…and +1 to the 'great concept but badly organised'
Great atmos too and the summer ones have had decent weather.
I've done the first two, as nickegg says they had to miss out one section from the results on the first event. For the second event my chip timing was way out on one section and I spent about two weeks afterwards emailing the timing company trying to work out what it was likely to be (although they were very nice about it).
It's tricky as organising timing over such remote areas is difficult, but they need to switch to a different timing company with newer, more sensitive kit.
They have issues with marshals who don't space people out enough on some of the sections – particularly the hill climb if you do the enduro option.
The slight overcrowding could be controlled with set start times or setting people off in waves of some kind – but that might take away from the relaxed atmos of the event.
Do it anyway and see how you get on, if they manage to keep the timing under control you'll probably enjoy it!
