|Snow at the summit of Alpine Loop|
Of course climbing I was plenty warm. The fat bike isn't particularly fast so I didn't hit the summit until about 11pm. There were remains of snow starting at Salamander Flats and continuing up to the summit, but never any real accumulation of snow.
I had to be careful on the decent because I really wasn't dressed for the combination of cold and wind on the way down. Used a lot of brake to keep the wind chill down, but still got my hands, feet, and legs cold. Once I got out of the canyon and could start pushing again everything warmed up fine, but the cold on the legs resulted in a bit of leg cramping and pain in the knee.
I have decided I really don't like the tubeless setup on my fat bike. It just seems the low pressure of the tires and aggressive riding tends to break the seal too much and I loose air a lot. I had to pump up my rear tire three times during the 55 miles and 7ish hours of riding. I definitely won't be going tubeless on the South Pole expedition. At -40° F the sealant would freeze and overall it just hasn't been reliable.
