I did Skyline in early October, I wasn’t impressed 🙁
The final decent is amazing, but the general feel of the thing is back to front, we seemed to climb on hard singletrack and then descend on fire roads.
When we did ‘descend’ on single track it was more traversing, everytime I got into a bit of flow, there was a bit of unexpected uphill which completely put me off.
Pretty much all the other routes and the final descent are very good trails, although I would take some skillz or armour. I took neither and rode into a tree after unexpected taking off over the awesome rolling final descent from… can’t remember which one. It really hurt.
