The joys of winter bicycling in the Alaska Interior

From this post:

Cold weather has been a struggle. I bivied just below Rainy Pass one night as I pushed my bike through the knee-deep snow for 45 miles. My thermometer bottomed out at 20 below. I bivied again last night at Sullivan Creek when I kept literally falling asleep and falling off my bike. I woke up after three hours and set out to pack up, but it was so, so cold. Everything was frozen solid. My chemical warmers had turned to ice bricks and I couldn't make them go. I crawled back into my bag and waited another couple hours before attempting again. Again, couldn't quite handle the cold. I finally just decided to wait until daylight and stayed in my bag until 10 a.m., but didn't sleep much. I woke up to a 35 mph headwind and single digit temperatures. Ground blizzards were out of this world. Again, glacial pace.
