Alright, time to hit the trail and see how this new-and-improved knee handles it!
With regular stretch breaks, and rolling with the tennis ball every time I stopped it held up! At least 90%, if not 95%. Enough to go almost 19 miles, anyway.
Sadly, I think we're leaving the windmills behind. I'm gonna miss them, if for no other reason than they imply a breeze. Oh well.
