Flying down a concrete drainage ditch into British Columbia's Howe Sound looks ridiculously fun, but it's also been done before. So to up the ante, after each kayaker sped down the chute one by one, five of them piled onto a massive paddleboard to slide down together.
The group, TeamSuperTramp, was led by adventure videographer Devin Graham, who travels the globe pulling off stunts like urban kayaking. In a behind the scenes video, the kayakers explain that due to the rocks at the bottom of the drainage ditch, the stunt wouldn't have been possible during low-tide. We also learn that they had to develop a 200-pound frame to place under the large paddleboard in order to hold them all and to prevent it from being destroyed by the concrete.
It's not the first time someone has kayaked down this drainage ditch. Kayaker Ben Marr made his "Lions Bay Slide" back in 2013.
