Altitude equals cold. Wear every layer you have. Don’t forget that the air is thin so you still need to breath through it all.

Can’t imagine what it would be like to ride at altitude. You and the bikes have done well.
Take care in the rare air!
Thanks Andrew. Fortunately you get used to it pretty quickly. At least we did.
