My injuries of last year are healed, but there is a good amount of scar tissue in both quad and hamstring.

I am noticing that when my rides exceed 2 hours, or if there is a lot of climbing, occasional that scar tissue starts to twinge. I always back off when this happens, but it is getting frustrating. Between this and the weather I've been unable to build my mileage up to where I would like to see it at the end of June. Please note I am avoiding the use of the word "should"

This is not a new injury, or a return of an old one. This is not pain, there are no signs of inflammation or anything like that; I certainly learned all of the signs of injury last fall when I was carefully ignoring it all.

The twinging stops immediately when I either stop or avoid climbing for the rest of my ride. This makes it quite challenging to prepare for a ride called "Brown County Hill Challenge" in October.

I am going to break out my roller and start rolling that area well a few times a week. Is there anything else I can do that will help?
