Injured

I went for a long run a week ago around New Glasgow and I have had a very sore hip ever since. I was wearing fairly old sneakers which could be part of the problem. It was also a very hilly route. I am not sure what the exact cause is. I took most of last week off and then ran for about an hour yesterday. My hip is still sore but not as bad. I am going to buy new sneakers this week to see if that helps. I also wonder if I have over stretched things by doing yoga too agressively. I think that is also possible. Otherwise, I am hoping to get back to my routine and also start doing more indoor spinning. I need to get my trainor set up for the winter. I purchased a new cyclo cross bike and i hope to use it a bit outdoors this winter. It is hard to believe that i will be heading to Tucson in about 2 and a half months for cycling. It helps make for a shorter winter.
