Trying to log 80 miles each week on the static bike

Have been doing 10 miles each morning this week on the static bike. It takes me about 40 mins to warm up hit the target at mid resistance and coold down. If I drop the resistance back I can pedal at speeds up to 19 mph on the bike but it doesn't feel as realistic. Still its a good training aid while the weather is cold, and easy to do with time constraints.....
