I am happy for you. The last time I ran a half marathon was about 20 years ago. It was so fun! I must say, I started a commitment to yoga in January and I am amazed. I feel so much stronger, more flexible and core strength is much better. (I had a yoga teacher who was a runner encourage me to take it) You should really! There is a YouTube show by the name of Yoga with Adrienne .....she is so sweet, and very good. Check her out! (It'll help your running ;) )
