Find ways to enjoy the monotony. 🙂 Changing up routes can help. Throw in the occasional higher-speed section. Alternatively – I’ve run my routes along the Charles River so many times that I tend to focus more on thinking through some ideas, observing what thoughts pop into my mind, etc… my version of meditating. If you run with headphones, try leaving them at home for a couple of weeks and seeing how it goes.
If you can get an hour in every day, that’s excellent. Keep at it. Also keep an eye on (1) finding low-hanging fruit wherever you can, like strength or mobility, and (2) aiming for one long run per week that makes up ~20% of your weekly volume.
