Enitsirk, I don't have an answer, but had to commiserate about the boyfriend and the advice. Back in college (I ran 3 - 5 miles a day) my boyfriend ran with me a few times, until it became dangerous for him to do so. One time (I was slow, just jogging), he told me "I could run at this pace for days and days on end!" I told him to go to....well, I suggested he move to a warmer climate.
He quit running with me at that point. I think I was mean, maybe... :shrugs:
