On a knife blade.
Grist cannot be held responsible for the crapping of your pants while watching this helmet-cam of daredevil cyclist Geoff Gulevich going down a mountain:
The GoPro video of Gulevich’s ride is from the Red Bull Rampage in Virgin, Utah — an exclusive, invite-only mountain bike competition so dangerous it was cancelled for several years — so it’s prrrrrobably not anything you’d encounter in your morning commute.
Plus, Gulevich is a professional mountain biker, so don’t feel guilty if you’re not as daring on two wheels. After all, YOU risk getting doored and T-boned if you ride in the city, whereas THIS punk only flirted with the edge of a cliff. Pfffft. He’s got nothin’ on rush-hour San Francisco.
