25 mph average is racing speed. Elite type riders not your average, but fit Joe.

I know it is winter, but try to get outside to ride. I would also try to up the mileage a bit more. I ride double what you ride and I am just a slow chick.

To get an idea of where you rank, look at club ride speed categories. This is from the Philadelphia bicycle club.
