E:60 on Tuesday, Nov. 1: "RISK" on ESPN

E:60 will dedicate its entire November 1 show (7 p.m. ET, ESPN) to exploring the concept of "RISK" through some of the world's biggest risk-takers and top risk activities. Segments of Tuesday's "RISK" show:

RISK - Extreme Kayaking, Tyler Bradt: Legend of the Falls
While most kayakers are content navigating frigid, white water, Tyler Bradt seeks higher adventure. Bradt, 25, is a thrill seeker who holds the world record for kayaking down the highest waterfall. E:60 looks at Bradt's rises and falls as one of the world's best kayakers, including a harrowing adventure when he broke his back during a controlled plunge down a 90-foot waterfall earlier this year, and how he miraculously survived and came away with the ability to pursue his passion.

"Doing what I do, you can't help but look at stuff and consider the possibility of potentially dying. I wouldn't do the stuff I do if I was afraid of dying." -- Tyler Bradt

RISK -- Mountain Biking: Kings of the Mountain
Take glory, gears and guts, and mix them with an almost sheer rock face, and you have the Red Bull Rampage mountain bike competition. The mission takes place near Virgin, Utah, where free riders compete, picking any route they want between the start line and the finish line - which is hundreds of vertical feet below - capped by a wild ride off a half-pipe-style wooden ramp. To get in, you have to be invited. And to be invited, you have to suspend fear and defy gravity. E:60 documents this hairy thrill ride, set against the rugged and unforgiving backdrop of Utah, which can be breathtaking - and often bone-crushing.

Land, Sea & Air
Three men, three world record attempts, one common calling - RISK
On land (High Lining): With just a pair of jeans, a T-shirt and two bare feet, Dean Potter walks high above the earth on a tightrope, over a nearly 3,000-foot drop, without a harness.

At sea (Free Diving): Free diver William Trubridge uses his body, two bare feet and one breath of air to plunge hundreds of feet down into the world's deepest blue hole, and back up again.

In air (Space Jumping): Before there were astronauts, there was Joe Kittinger, who in 1960 tried to become the first man to jump from the brink of space -- 22 miles above Earth, from a weather balloon.

Why Risk It?
Kayaking off waterfalls, riding mountain bikes down near-vertical mountain faces, tightrope walking - who willingly risks life and limb in these kind of challenges? And perhaps, more importantly, why? E:60 consults experts to try to find the answers.
