You probably wouldn’t look twice at Mirinda Carfrae if she sat down next to you at a Boulder cafe. At five feet three inches, the muscular 31-year-old appears to be just one more exceedingly fit Front Ranger. In reality, she’s a world champion Ironman athlete who can, in succession, swim 2.4 miles, bike 112 miles, and run a marathon faster than almost any other woman—and all but a handful of men—on the planet.
The People’s Republic has become one of the largest bases for championship-caliber Ironman prepping in the country. For three decades, more male winners of the Ironman World Championships in Hawaii—held annually in October—have trained in Boulder than anywhere else. Last year, Craig Alexander and Chrissie Wellington, who both train in Boulder, took first in the men’s and women’s competitions, beating out 1,296 and 475 competitors, respectively. Carfrae, an Aussie who began training in Boulder in 2005, placed second.

So what is it about Boulder that draws the sport’s best? The boost in blood chemistry (an increase in red blood cells helps carry more oxygen to your muscles) attributed to working out at higher elevations is only part of the answer. What sets Boulder apart, local Ironman athletes say, is the training infrastructure: clubs with 25- and 50-meter pools that cater to serious swimmers; well-maintained roads with mountain climbs that are safe for cyclists; top-quality sports massage centers; and access to seasoned coaches and trainers, like six-time Ironman world champion Dave Scott. “You don’t feel like you’re out of the ordinary being a professional athlete here,” Carfrae says. “We’re not freaks of nature. We’re the norm in this population.”
Tips for getting into triathlons
• Join a group.
“I encourage people to try and train with others,” Carfrae says. “It’s always nice to be part of a team.”
• Start short
Try sprint triathlons—about a ninth of the distance of an Ironman.
• Don’t expect too much
“Just try and enjoy the race and finish it,” says Paul Ambrose, who won Ironman Australia in May.
