The Team Are Bike Park ace goes for a ride in the woods with the European Downhill Cup winding up in the Black Forest!
After a steep downhill section, the riders' eyes straining to see in the reduced light of the wood, comes a pedalling section and then more downhill acceleration as Wallner and the rest have to watch out for tree roots.
A series of jumps and a wall ride means there's plenty of variety, with multiple line choices, while slippery rocks dotted around a rapid end mean you have to be careful not to wipe out on the last corner!
Seeding for Sunday's finals takes place on Saturday. Check redbull.com/bike for the latest results from the riders...
