Knee pain

I did this morning exercise and my knee was very sore throughout the run. My hip felt okay (not great). My muscles are still very sore and it took a lot of effort to walk to work. I'm still happy and confident. I'm thinking that it may be fun to also do the Las Vegas Marathon in January.
