British mountain bike racer Dan Atherton created the most dangerous course in the world in the village of Dinas Mawddwy, Wales. He filmed himself doing with a GoPro while competing in the Red Bull Hardline 2016.
He had to navigate tight forested sections, massive boulders and drops. It also includes an amazing 50-foot gap jump.
Atherton finished in 13th place, marking a time of 3.47.66. The winner was Bernard Kerr, also British, with a mark of 3.32.46.
