I mostly walked today. My knee is still bothering me, and I feel like I need to get it feeling better before I run on it much more. The running bothers it, so I really felt like my body was telling me to back off. Hopefully I can figure out what to do about my knee so I can get past this roadblock quickly!!!
2.85 miles, 36:30.
ETA: Sounds like this might be what's wrong.
