Yvon Chouinard once said WHEN EVERYTHING GOES WRONG—THAT’S WHEN ADVENTURE STARTS. If that’s true, then my 5-week expedition to Antarctica was the adventure of a lifetime. Not only did things go wrong, it seemed that nearly anything that could go wrong, did. And while I’m no stranger to adversity or physical suffering to achieve an objective, I can honestly say that this was the most trying and at times, psychologically demanding trip I’ve ever been on. But, let me start at the beginning...

In Japan, we spent two full days simulating the harshest mountain environments possible while I wore the 8000-Meter suit and walked uphill on a motorized treadmill. A big screen that dominated one entire wall of the chamber projected mountain scenes, making the sterile, stainless steel chamber seem a little livelier. Meanwhile, the control room technicians monitored my body temperature and used infrared cameras to determine how effective the WarmCube technology was at insulating me from the cold, wind, and rain. I felt a bit like the proverbial hamster on a wheel. The suit was perfect, however, and I knew it would do the trick in Antarctica, where I planned to climb the continent’s highest peak, Vinson Massif, ski to the South Pole, and climb the highest volcano, Mount Sidley. It was an ambitious itinerary, never attempted in a single “season” (i.e., austral summer, opposite of the northern hemisphere) by any female, but I rationalized that it made sense to do everything at once, since the logistics of simply getting to Antarctica are one of the biggest hurdles to overcome. It was going to be the longest and coldest expedition I had ever undertaken.

Antarctica was a special project for me. It was the last continent I had yet to set foot on, and the culmination of my mission to complete the Seven Summits, by scaling the highest peak on each continent. Of course, I would be collecting data again, since much of what we know about polar exploration and physiology is largely based on military research and predominantly involved men. I saw another opportunity to provide insight into the unique requirements of female athletes in extreme cold, and high-altitude environments. From a nutrition and exercise physiology standpoint, I wanted to know what happened to a woman’s metabolism and thermoregulation during prolonged polar travel. How many calories were burned at rest and during activity? How much of that was from fat versus carbohydrate sources? Did body temperature regulation change over time to adapt to the environment? How stressful were all of these things—environment, exertion, limited nutrient availability—on the body during 30 days or more of exposure?

To test these questions, I wore a custom garment designed to monitor astronauts’ vital signs at the Space Station. That’s right, I went to the folks responsible for keeping astronauts safe in space (Astroskin, Carre Technologies) in order to continuously monitor my biometrics. Energy expenditure, heart rate, breathing rate, skin temperature, blood pressure, EKG, oxygen saturation, all of these vital signs, basically the equivalent of a wearing a hospital bed, would be recorded during my trip. In an inconspicuous tank top embedded with advanced sensors, tucked away underneath my WarmCube layers, I would be a walking science experiment at the end of the Earth. Sure, it would cost me a few extra pounds worth of equipment, but what the heck, this was for science.
