What a Disater!!

What a difference a day makes. Wednesday I had one of my best training runs ever. Thursday I run 100 Yards and have to stop due to pain. However I walked a bit and was able to run through it but it had/has me scared. After my race I was very sore in the right glut. It seemed to dissapate but reared its ugly head yesterday. I'm hoping I don't have Piriforms Syndrome. Anyway, lots of Advil, Ice and Rest for today. I'm hoping I can continue my 1/2 marathon training uninterrupted. If need be I'll rest on Saturday instead of my easy 3 miler. I do not want to miss Sunday's 7 miler. I'm nervous.
