40yo runner here, been running for about 8 years averaging about 70mpw for the last 4 years. Last year I had periods where I was doing 90-100mpw during the winter and summer. This year, running just seems to be more painful particular on the knees. Twinges of pain in the knees become more common in runs. The other day I noticed that my knee was making a clicking noise as I was walking down some steps. Also, it seems that around the 10 mile mark of almost every run, the pain becomes more pronounced.
I'm hitting the trails more often and trying to a 9 day training week to give myself more time to recover between harder runs. Just wondering if other master runners have gone through this and what you did training wise to get through it. Any supplements I should look into that could help the knees? Should I incorporate weights into my training? I'm thinking maybe I might have worn some of my cartiledge away.
I'd like to be eventually get back up to doing 90-100 but at this point, I'd be happy if I could just run pain free averaging 70.
