I'm reaching out for some ideas as to why I'm having issues with my knees.
I'm 22yo and have only recently started road cycling 'seriously'. I try to ride ~30/40mi on Wednesdays and ~60/70 over the weekend, slowly building up on distances.
After about 10mi, my right knee starts feeling a little strange. The only way I can describe it is as if it's being filled with jelly or something of a similar density. I think it swells a tiny bit but nothing that you can really notice.
