I wouldn't go down that at even a quarter this speed!
Rider Speeds Down Crazy German Bike Trail In Heavy Fog

This is a video of mountain biker WolfPack Adventures providing a high speed tour of the Green Hill Bike Park in Schmallenberg, Germany. The rider says it’s the most unique bike park he’s ever ridden, and it shows — those trails are wild. And in the heavy fog it looks like he’s racing towards Silent Hill. No thank you, Mr. Pyramid Head! Also, if this had been me I would probably still be there trying to find all my teeth in the leaves.
