No matter what kind of workouts you're doing, you need recovery days. Daily hard workouts are not going to improve your overall conditioning without recovery and nutrition. There are many websites and books that discuss training, overtraining, etc. I suggest that you avail yourself of those resources. For tracking cycling workouts, Strava is an invaluable app. It can help you figure out when your strength and endurance are improving or declining by comparing past and current segment times and hill climbing power output estimates. You can also plug in heart monitor data if you are so inclined.
