Yeah, I guess maybe the course isn’t everyone’s cup of tea. As far as being “technical” the downhills aren’t technical in the sense of lots of wet roots and rocks but rather in the sense of “how dare they put this descent midway through an XCM race!” At speed they’re technical.
It does remind me though: the last time I rode the SM100 we camped next to a group of roadies from upstate NY who complained about how much gravel was on the course before the race, then about how much singletrack after the race.
