Its the lower part thats been resurfaced, maintenance work has been done to the top bit too (just filling in holes really), the rocky step is still there. The lower part was always pretty smooth and fast with a few loose corners and a few breaking bumps but nothing at all technical. When I was last there in April it was BMX track smooth, which made it ultra fast and had taken away all the puddles you used to get in the compressions in the woods.
I don’t think Whinlatter needs to be technical, there are plenty of technical options within a few miles of the place. For me it provides a great place for a quick early morning spin, where I don’t need to worry too much about hurting myself whilst on my own and where the challenge is doing bits of it/all of it without stopping as fast as I can.
