LBTC, I don't know how I missed your reply - so sorry! I do yoga, but will try to be more mindful about stretching the ileopsoas and see if that helps.

Sally, Yup, it's me.

Had another bout of diarrhea last week, but I think it was related to my period - no blood in the stool this time. So, I only ran one day last week and laid off after the diarrhea started (had my last bout on Saturday). I've got a 10-miler planned for tomorrow evening - wish me luck!
