Cold-season weekly rides?

I'm looking for some rides to do with people who like a good ride. Not a slow cruise ride, something that's a bit of a challenge. I go out on the Donut Ride when I can but I can't always make it out or would also just like a change of route every now and then. It also seems like most weekly rides end around this time when it's cold and a lot of people don't like to go out riding.

I'm not one of the fastest riders but I do keep a good pace. (some of the Donut guys are fast as hell)

I've done a bunch of century rides and many more metric centuries. Anyone interested in adding a person to their group, feel free to email me dillingerescaped at gmail dot com

im a 27 year old guy and usually work weekdays 9-5.

thanks.
