Managed to get injury #4 on my quest back into 50 miles. I felt great on Tuesday night and found myself running in the low 7 minutes w/o any distress. Decided to do a few fartleks in the 6:15 pace and felt great. Woke up with a sore butt. Doing my typical Google diagnosis, I found that I have: Piriformis Syndrom Going to take a few days off and chill out.
