How about that longer uphill bit when you're heading east on the BP just before the stairs of doom?? I've only made it up that a couple of times and now with a dropper post there's no reason to not continue.
I have been able to get that most times now especially with the ground grippy. Don't know if I would have the legs or lungs to make it on the big bike but good to go on the trail bike.
Last summer it was really hard with everything loose and covered in an inch of dust.
