The Grey Earth Trail

Highlight (Segment) • Trail

Special stage 13, The Grey Earth, is unique to this part of the world. What looks like a combination of grey cement dust mixed into tarmac that has then rolled down a hill like lava, has then set into long flowing ridge lines of incredibly grippy and fast rolling trail. For the riders, there's a suggested line laid out for them but the opportunity to go "off-piste" and choose a quicker line is there for those that want it.
