Clearly communicating the difficulty of a course is something the club continually struggles with, which is unfortunate, because newcomers/beginners/up-and-coming-ers suffer the greatest impact.
I looked at last year's short advanced Bog Slog on Route Gadget
and controls 4 through 7 look devilish for an intermediate orienteer to achieve, and number 10 on a subtle veg boundary looks particularly horrible.
That's the kind of course that could take an enthusiastic intermediate orienteer and push them over into, "I can't effing do this, what the hell was I thinking trying to get into this sport?"
But how is the public to know all the things you just said about this year's short advanced versus long advanced? All the website says is that Short advanced is shorter, not that what it's cutting off is significantly more off-trail stuff.
