I haven't done any running since my race this past weekend. I seem to have developed a strange twinge in my left quad. It's almost like when I put my weight on it to walk it feels like its going to give out. The strange part is its really hard to tell exactly where it's coming from? I'm thinking it may be a small pull. I rode my bike yesterday really slowly with my Mom and it never tweaked until I would walk on it? Not sure what that's all about but was hoping it would be gone by today so I could go run. I wonder if I should try to run on it or just wait it out?
