Well, turns out the 25k probably wasn't a good idea. Initially I felt great, running at Afton again felt so good. Kind of like going home, it just felt right. The first 5k went really well, then when I came down a hill in the back forty, the knee kind of buckled or I guess it was more of a wobble and from that point on, it was just about getting through it. I could not run down hill very well at all. By the time I got to meat grinder, I couldn't walk down the hill, I had to turn sideways and kind of side step my way down.
I made it eventually to the finish, it was great seeing some familiar trail faces but I will need to figure something out to be able to run trail :-(.
