Probably the wrong advice for Zula, who responded by releasing the brakes and letting the bike run downhill at a speed that was on the edge of being out of control. She managed to slow it down just enough to avoid spinning out at the next switchback, got it fishtailed around, built up speed again, and then had to slam the brakes hard to avoid a head-on collision with a camo-painted four-wheel ATV coming up the other way.
