Try changing your 5x a week rides from all the same distance (guessing that's what you're doing) to something like 3x 25 mile rides, 1x 35 mile 1x 50 (may need to work up to doing 50 miles regularly)... throw in some hills. Hills believe it or not are a good thing, and can help make you stronger... If you don't count miles, then go by time instead... do 1.5hr rides 3x a week, then throw in a 2hr ride and a 3-4hr ride. Do something like that for a couple weeks, then adjust it as you need to. Eat a proper diet, get good sleep (if possible), enjoy the ride
