Only very strong riders and likely not solo efforts.
15 MPH to 18 MPH average speed is more likely for most riders on solo rides more than 20 miles.

Many cyclists and runners are surprised at the level of difficulty encountered when they take up the other discipline for the first time. Fitness in one discipline does not correlate well to fitness in the other. I think you are seeing this so give it time and keep riding.
