If you want to ride your bike long distances outdoors, but can't due to weather, ride your bike a lot indoors on a trainer or rollers. Yes, it makes a heckuva difference. You don't really have to ride outside at all. You just have to simulate it indoors. That means the whole gamut of endurance rides, intervals, etc., but done on a trainer. Say 8-9 hours/week. And this must be done on the same bike, or a bike with exactly the same saddle and fit as your century ride. Because you can't ride hills or upwind indoors, you must do endurance rides of at least 1.5 hours, plus intervals, ranging from sets of 15 minute intervals at LT to say sets of 5-8 minute anaerobic intervals. As said above, ignore the miles and just do the hours.
My wife and I just completed a century yesterday having done essentially nothing for the last month other than ride indoors, ski, and snowshoe.
The above is conditioned on your knowing how to eat, hydrate, and pace yourself on a long ride. My wife and I have done many long rides.
