Kevin Fedarko is a celebrated and well-heeled journalist, accustomed to dropping in on an exotic place and extracting a story, often in less than a week. But in 2004, he left his job at Outside and went looking for something deeper and more meaningful: a story forged over months and years. He ended up at the bottom of the Grand Canyon at the helm of a boat full of poop called the Jackass.

More than two decades after he radically transformed big-wave surfing, Laird Hamilton is still a dominant force in the sport. As detailed in the new documentary Take Every Wave, Hamilton is again pushing the edge with his new obsession, hydrofoil surfing. His wife, Gabby Reece, is a former professional volleyball player, model, author, and currently the host of the NBC reality show Strong. At their home in Malibu, Hamilton and Reece have created an elite training boot camp where they torture themselves daily, run extreme pool training classes, and constantly experiment with new approaches to exercise and nutrition. In this first installment of a four-part look at the science of performance, Outside editor Christopher Keyes pays the super couple a visit to try and understand the methods behind what sure looks like total madness.

Killer frogs! Forest-destroying moths! Bird-eating mongooses! These may sound like biblical plagues, but they’re the result of bad human decisions. All too often, after an invasive species shows up in an ecosystem and wreaks havoc, our response is to import another species that will eat the first one. Then, of course, the predator turns out to be even worse for the environment. Except now, maybe, we’ve figured out how to do biocontrol right. And as it turns out, some of those infamous mistakes weren’t so bad after all. In this story, our friends at New Hampshire Public Radio’s Outside/In reexamine the history of biocontrol to find out the truth behind the horror stories and understand why throwing hungry critters as a problem has enduring appeal.

Jack Johnson is known as the world’s mellowest pop star. A surfer raised on the north shore of Hawaii, his acoustic strumming has been the default soundtrack to good-times beach living for more than 15 years. But these days, something’s up with Jack Johnson. He’s decided that in the current political and social climate, quietly supporting environmental non-profits and greening the music industry isn't enough. He’s ready to speak up, beginning with his new album, All the Light Above It Too. Executive editor Michael Roberts chased Johnson down to ask: What happened?

Rebecca Rusch is called the "Queen of Pain" for a reason. She's a three-time world champion in the 24-Hour Mountain Bike race, the 2011 National XC single-speed champion, and she's won the Leadville 100 mountain bike race four times.

But a couple years ago, Rusch decided to take on an entirely new kind of pain. It would involve an epic ride along the Ho Chi Minh trail to find the crash site where her father, a U.S. Air Force pilot, was shot down when she was just three years old. Her emotional journey is the subject of a new documentary called Blood Road. Rusch met up with XX Factor host Florence Williams at the Telluride Mountainfilm festival to explain why this was the hardest ride of her life.

In 2012, Vanessa Garrison co-founded GirlTrek, an organization with a simple goal: get women walking for 30 minutes a day. Now 110,000 walkers strong, GirlTrek is a national force. The story of GirlTrek is about health, justice, power, and survival. But mostly it’s the story of trying to change your community, and the world, through something as simple as going for a walk. To understand how GirlTrek was started, how it blew up, and where it’s going next, Outside contributing editor Florence Williams takes a rambling walk with Garrison around Washington, D.C.

The swamps of Alabama are one of the most biodiverse places on earth. They’ve been called America’s Amazon for the remarkable number of species of fish, turtles, mussels, and other aquatic creatures that live there. Not so long ago, the Alabama sturgeon was a staple of life in these parts. The funny looking fish swam here for millennia, migrating hundreds of miles up streams to spawn. They were caught and eaten in the tens of thousands. Then, a decade ago, they vanished. To the protectors of Alabama’s swamps, this presents a terrifying question: If the rivers can no longer support sturgeon, what does that say about the water we swim in and fish in and drink?

Among most important advances in sports technology, few can compete with the invention of the sports bra. Following the passage of Title IX in 1972, women’s interest in athletics surged. There was just one problem—actually, make that two problems: their breasts. Boob bounce hurts, as women getting in on the jogging craze found out. Then some friends in Vermont had an idea to stitch a couple jock straps together to build a contraption to keep things in place. Their creation revolutionized women’s participation in sports and launched what’s become a multi-billion-dollar industry. Today, high-tech boob labs are helping designers make ever more effective—and stylish—iterations, even for athletes with DDD cups. Outside contributing editor Florence Williams, author of Breasts, looks back at the game-changing invention, takes measure of just how far we’ve come, and points towards an even brighter, bounce-free future.

Nearly every sport can point to a comedy taking aim at its flaws. Hockey has Slap Shot. Car racing has Talladega Nights. Skiing has Hot Dog. And dodgeball has, well, Dodgeball. Now cycling can claim its own: HBO’s Tour de Pharmacy, featuring executive producer Andy Samberg and a laundry list of A-List celebrities. It’s about damn time. Is any sport riper for parody? Besides the rampant doping, there’s the leg shaving, the spandex, the team names, the whiteness, the stuffy British commentators, and, of course, the curiously misshapen bodies. The film sends up all that with a gonzo storyline that clocks in at a breezy 38 minutes and features—spoiler alert—no less than four shots of full frontal male nudity plus recurring commentary by Lance Armstrong. We caught up with Samberg to find out how the film came about, why he chose to pick on cycling, and his fetish for wiener gags.

When something goes wrong in the wilderness, someone needs to evacuate and get help. When that someone is you, and every minute counts, the stress is enormous. And you just might not be fast enough. Scott Pirsig and Bob Sturtz were on a spring canoeing adventure in the Boundary Waters, a million-acre wilderness in northern Minnesota, when Bob suddenly started acting weird. He complained of a headache. Then he became disoriented, lost control of his hands, and stopped speaking. He’d suffered a stroke, which meant time was everything: the longer it took to get him to a hospital, the more brain cells he’d lose. If it took more than a few hours, he’d die. So Scott zipped his friend into his sleeping bag, begged him to stay put, and paddled off at a sprint into dense fog. What happened next forever changed both men.
