I've done some multi-day touring rides with my own gear. Usually I find after 2 consecutive days of cycling 80-100kms. per day, the 3rd day I want to scale down to 10-15 km. to at least rest but still retain muscle memory. It would a slow, tootling type of day.
By the 5th day or so, I really do need to not bike at all for such a touring ride. Then the next day I'm refreshed.
I'm 53. I've never tried compression tights. Just a short ride or 1rest day helps me.
For a normal ride to me about the city would be 15-40 km. per day. I've been on the bike daily for the past 20 days. That's very normal for me during spring to early fall-- to cycle for 14-25 consecutive days before I take 1-2 days off. It's weekends I do the longer distances. But I am not racing against my own time, I'm just cycling at a speed that suits me and for what I want to do along the way since cycling is part of my whole lifestyle ...being car-free for so many years.
Once you get used to cycling the way I do it, your body gets hooked to the natural drug endorphins that cycling/exercise produces or that natural "high" feeling.
