How much rest do you all give yourself?

42m, running on a 4 week rotation with 2 weeks at about 30 miles with one workout run per week, one week with about 22 miles with 3 workout runs and one week with about 16 miles and one workout run. I lift 2 days a week for an hour with a trainer at pretty high intensity and and 1 day a week by myself for 1-2 hours with a bit lower intensity.

I have one day per week where I don't do any structured exercise.

I've kept this up for a while now (it's been about a year and a half since I added the weights, running at about 15 miles per week for several years prior).

I've generally taken time off from all exercise if I'm actively sick or taken time off either running or weights at a time for minor injuries, nothing more than a week off either activity. In addition to that I've taken some trips that have reduced my exercise, although on those trips I'm usually pretty active (~20k steps per day).

Overall I'd say I miss maybe 2-3 weeks a year off of either running or weights at a time plus another 1-2 weeks off both at the same time.

Is that not enough rest? I'm starting to wonder if I should be taken some longer breaks or periods of lower intensity.
