Going 360mph on a two-wheeler, taking a leap of faith into a Chinese sinkhole, and biking a high wire across Newark: all things you won’t be doing this month.

The Fastest Man on Two Wheels

“When things go right it’s the most awesome feeling there is,” says Rocky Robinson, who broke the land speed record for a motorcycle on September 26. On the way to 361 mph, which bested the old mark by 10 mph, the canopy on Robinson’s Top 1 Ack Attack streamliner came open about two and a half inches. “When it popped, it got real turbulent,” he says. Robinson needed a second run on the 12-mile course at Utah’s Bonneville Salt Flats to make it official. He hit 359 on the second pass. – Dacus Thompson

Flying Down a Chinese Sinkhole

After riding a converted ski lift chair across a cable spanning the 2,054-foot-wide mouth of China’s Tiankeng (literally, “heavenly pit”), 23 BASE jumpers, including Miles Daisher, Shane McConkey, and Chuck Berry, leaped into the world’s largest sinkhole on October 2. As thousands watched, Berry inched out on the cable over the 2,231-foot-deep hole and jumped, executing a double backflip on the way down and landing inside a huge opening at the bottom of the rock wall. “The cave is supertight,” says Daisher. “That was a giant concern for us — the hospital was 12 hours away!” Not to mention the 3,056 steps just to get back out of the cave. – Martin Mulkeen

Biking the Newark Skyline

In October, Nik Wallenda pedaled to a world record for the greatest distance traveled by bicycle on a tightrope. With no net, he rode a bike across 235 feet of wire between two cranes 135 feet above the streets of Newark, New Jersey. Wallenda, 29, the seventh generation of the legendary Flying Wallendas family, says preparation is a must, especially for his planned tightrope walk across the Grand Canyon. “If I’m going to walk a mile across the Grand Canyon, I’m going to walk 10 miles on a wire before that,” he says. – Martin Mulkeen
