Yesterday I rode in one of the top three most extreme conditions of my days.
I realized right away that it wasn't going to be about the carve- it was going to be about survival. The other two times I wimped after an hour or two. Yesterday, I went from 8:59a to 1:30p with two stops, performing required tasks (throw a "tree-P", light a lighter, etc.) just to see if I could. Maybe my brain froze.
It was -12 F(ambient) at the top of Dipper (Heavenly) and about 2 F at the top of Sky. With gusts to 50, Skyline trail was life threatening. The visibilty was from nil to 40 feet with the occasional hole in the clouds.
Lessons learned:
The snow at this temp is a perfect hybrid between sand and velcro- no glide.
Your nose completely stops functioning somewhere between 2 and -5 F
Saliva really does keep the goggs good
Continual white-out scarving of a 186 PureRace leads to significant lactic retention in the front quad
Beer is required ( see required tasks above)
Some things are more fun to talk about
