Used to spend alot of time in Norwegian winters with the Army.

The bonus there is that there is no moisture on the outside, it's all frozen solid.
A UK fell runner is probably at best (some try to avoid even that weight) only dressed for running or quick walking, or reliant on speedy recovery if immobilised. Sweating is the default position and UK fells have a tendency to be windy and wet with a temperature often hovering either side of freezing. Throw in exhaustion and low blood sugar and, God forbid, an injury and you have a bit of a 'mare to survive.
Editted to add. Of course, this is why we like the challenge of the sport. Just trying to emphasise the requirement to look after yourself.
