I did similar for about 25 years. I had one injury from overtraining (I basically ran 20 miles every Sunday morning for 6 months, in addition to two shorter runs each week) that ended up plantar fasciitis and I had to take 4-5 month off.

I stopped doing that sort of weekly long run after that and did a lot more in the 6-10 miles range.

Then during and immediately post-COVID shutdowns, I just started running every time I felt stressed about something, and I started to neglect all the other holistic movements that complement running.

This ended up leading to a weird twinge in my hip that 2 years of focused strength training hasn't eliminated. Doctor says there is nothing structural but I don't run any more and I miss it often. There is a flow state I seem to get in somewhere just under to just over an hour in to a run.

The only other time I ever get in to that wonderful flow state is every once in a while when playing guitar, but it's rare.

I does feel good to run, and I miss it.

Could be arthritis.
