Extreme kayaker Ben Marr is at it again.
Last fall, the 24-year-old thrillseeker shot a video of his solo trip down a concrete draining ditch in the community of Lions Bay and posted it to YouTube, where it went viral.
In that trip, he claimed to have achieved a top speed of 54 km/h before being dumped out into Howe Sound.
When Marr, who is from Mallorytown, Ont., recently returned to the chute, he didn't go alone.
The newest GoPro video, posted to YouTube Tuesday and already making the rounds online, shows Marr and fellow daredevil Rush Sturges racing each other down the "Lions Bay slide."
"I think we should go in at the exact same time, pretty much," Marr tells Sturges in the video, as the two ready themselves to set off through a break in a chain link fence. "And then we'll duke it out."
"That sounds really scary, dude," Sturges said.
As Marr starts to pull him in, the 29-year-old from California protests: "Whoa, whoa, whoa. Seriously, that sounds sketchy."
"It'll be sick," Marr counters. "You should just calm down, dude."
The men, recording with helmet- and kayak-mounted GoPro cameras, launch in and end up sliding up the banks, spinning around and losing control as they gain speed.
Near the end, Marr make a move to pass Sturges and it looks as though he careens off course just before both get dumped into Howe Sound.
The YouTube post claims they reached a top speed of 72 km/h.
