Take a couple days off. Actually if you really have been doing this every single day for years, take a week off.
Doing the same thing every day is a poor way to train. You need both stress and rest in order to improve. You will find that you improve with proper rest.
I take at least one day off each week, and have another day be an easy day. The real training days are usually either long (3-5 hour) endurance rides, 2-3 hour fast group rides, or 2-3 hour rides with interval workouts. That's training for road racing; training for something else would be different.
