The top section begins in the trees on a familiar dirt and pine needle trail, then you emerge out into the open clearing greeted by a rocky trail that's fast flowing with lots of well-sculpted berms. The rocky trail surface is quite different to other tracks at thornielee but can be a nice break from the mud on wet days.

This trail is unsanctioned.

      Rocky and slippy in the wet I thought, but maybe my tyres are at fault. Berms didn't stand out but maybe hidden by the undergrowth!
      Still ,a fun challenge. I felt gumdrops was easier so I'm not sure about the red designation here

      We hope you've been enjoying Trailforks!
