Ended up making it Golspie today and think I pretty much covered all the blue, red and black routes.
Had a bit of a nightmare from lactic ladder onwards unfortunately as the weather turned really nasty slogging up the final fireroad at the top, then got 2 punctures early on the descent and after that rear brake failed so I was really tip toeing down for a while.
I think for me personally the red grade route and on up to one of the black shortcuts is ideal if I were passing again. Nice climb up that’s not a boring fireroad slog and some swoopy single track descending with a few features thrown in.
I’ll definitely be back next chance I get!
