The Wingra is a flat bar bike and will give you a relatively upright riding position. That tends not to be good for 20+ miles. But different people have different preferences. You should try out a bike with drop bars. Once you decide between drop bars and flat bars, figure out how much you're willing to spend.
You've said you're interested mostly in comfort and speed. These two things tend to be a bit at odds with one another. Up to a certain point, you can have both, but there's a threshhold somewhere where faster bikes are less comfortable to ride. You probably don't need to go that fast, so I would look for a nice comfortable road bike.
If you want something with flat bars, the Jamis Coda and Specialized Sirrus are good options. If you want drops bars, check out the Jamis Ventura or Specialized Allez.
Or ask you local LBS to recommend something. Ride a few bikes and see what you like.
