There are no rules in the underground TK Avalanche. It’s just the fastest rider from the top of the park to the bottom. Want to cut corners? Go ahead. Want to straight-line it through the trees? Yup, you can do that too, you can even give that rider next to you a little nudge. Somehow, Super Grassroots rider Markus Zieher survived the top to bottom mayhem and shared this crazy video with us!
