Training Week 16

So last night I decided to go for a run, and see how far I could go. In my mind I wanted to go 10. I did the first 5 mile loop and felt fine. I ran/walked a 12:30 min. mile pace and had NO pain. I stopped by the house after the 5 mile loop and changed socks since my blisters (from walking last week) were starting to bother me. I headed back out and when I got to mile 5.5 I decided that should be the end of my run. I never felt pain, but I felt something in my left knee related to the ITB which made me think it would be best to stop. Later on that evening, as we were watching the Redskins get eaten alive by the Eagles, I got up from the comfy chair I was in and my knee/ITB started to hurt when I walked!!! What in the world? I grabbed the foam roller and rolled myself on each leg and it went away. That was so bizarre. It seems ok today but who knows. I'm going to walk on the treadmill today and do some weights. My plan is that tomorrow will be a short run, walk Thursday, rest Friday and try to see how far I can go Saturday. Then I will evaluate what I should do for race day on 11/14. In my heart, I think it would be wise to switch to the half marathon. I am finally able to accept that and just know that there will be another time, another race and it would be best for me to heal first. I'll be the fist to admit that it's been quite a struggle to get past this disappointment, but I'm hoping I can learn a lot through this and help others who find themselves dealing with ITB during training.
