If you're a weekend waverer—should it be the bike, the running shoes, the paddle?—adventure racing might just be the sport for you. This medley of outdoor skills—usually including route-finding, trail running, mountain biking, and paddling—started as the brainchild of adventurous French journalist Gerard Fusil, who'd covered strenuous long-distance races like the Paris-Dakar Rally and the Marathon des Sables, and wanted to find another challenge. The first adventure race he organized, the Raid Gauloises (now held under the banner of the Raid World Championships), took place in 1989, a ten-day sufferfest through more than 300 miles of New Zealand wilderness.

The Eco-Challenge (www.ecochallenge.com), held in Utah's Canyonlands for the first time in 1995, brought this genre of grueling—some might say sado-maschistic—adventure to screens stateside. This competition was the brainchild of reality-TV honcho Mark Burnett after he took part in the 1992 running of the Raid. The televised series of the race (which first appeared on the Discovery Channel, covering the 1996 race in British Columbia), now beams adventure racing into as many as 944 million homes around the world each year.

Even though expedition-style races keep getting tougher, they've also spawned shorter adventure races for those looking to get their feet wet without the oozing blisters and sleep deprivation of a multi-day expedition. Most events now are beginner-friendly sprint races, averaging three or four hours, says Troy Farrar, director of the United States Adventure Racing Association. "It's a great stepping stone for people that can really give them the adventure-racing bug," he says.

And while classic adventure races involve coed teams running, pedaling, and paddling together—all while chasing down the next waypoint—new disciplines are continually being added into the adventure-racing mix, making wilderness adventures more challenging and more fun. Urban adventure races, like this summer's Quest Urban Adventure Race in Houston, can involve riding scooters and subways with the standard sports. No matter what the combination, adventure racing can take athletes of all levels to new challenges. "People get pushed to limits they've never been to before," says Farrar.
Pioneer: Rebecca Rusch

Rebecca Rusch stumbled into adventure racing by accident. "I just did it on a whim," says 36-year-old Rusch, "I didn't even know what the sport was." Now, it seems, she has an intimate association with all things adventure—the stalwart Team Montrail, which Rusch captains, won the 2003 Raid Gauloises, considered the world's premier adventure race, in Kyrgyzstan last December.

But the Chicago native wasn't a newbie to adventure sports. A college runner, Rusch got talked into doing her first adventure-racing camp while working at a climbing gym in Los Angeles, and had spent years as a river and climbing guide. Now based in Ketchum, Idaho, Rusch and team will hit ten competitions in 2004 in places from Borneo to the Canary Islands.

The sport's far-flung destinations are a draw for Rusch, whose feet have taken her to remote spots in Patagonia, Morocco, Australia, and elsewhere. And the ride is never boring. "I like the unpredictability the most," she says. In one Moroccan race, part of the event was to ride camels—luckily, she says, this section didn't count in the overall standings. "People got some really bad camels," she says, "but it was still cool."

Her next main event: the 2004 Raid World Championships in Argentina at the end of November, where she and her team are looking to retain their title. "Winning isn't everything," she says, but last year's victory "was definitely a pat on the back, like we were doing the right thing."
