Thai Energy Drink Carabao took a page from RedBulls playbook earlier this year by hosting an incredible looking PK Competition this past May. Dubbed Sky-Ladder Challenge, the event was held in Tianmenshan of Zhangjiajie in the Hunan province of China, where 20 international traceurs and 30 Chinese traceurs were invited to participate. This Course looks awesome and tiring, and the two videos below give you a good sense of it. The first is from Chinese news agency CCTV+, and the other is a POV video shot by Utah traceur Calen Chan, who did the whole course with a GoPro in his mouth! That's breath control right there! Take a look and enjoy.
