Last couple of days in Idaho, start to finish. Claire and I climbed the height of Everest in under 36 hours. 30+ hours of hiking, very little sleep, lap after lap. Every lap included The Wall, a 43% grade. Most treadmills max out around 15%. My feet were wrecked. My knee hurt. There were moments the pain almost brought me to tears. But you keep moving. Claire climbed 22,838 vertical feet, the height of Aconcagua. Watching my wife keep grinding was the best part of the whole thing. Eventually you stop thinking about Everest. It's just one more lap. Then one more. At some point your body starts begging you to stop. Your mind starts giving you permission to stop. That's where you find out who's actually in charge. 29,029. Done. I asked last week what hard thing you've been meaning to do this year. Anyone started theirs? Dr. Matt
