I have been running very responsibly this summer, only about three-four mile runs for about 4 days/week with a longer run one weekend day. Usually only logging in about 20ish miles per week. BUT my hip is still moaning a little and my knee on my other leg is causing me a little discomfort while running as well. I just don't feel like I am running enough to warrant any pain.
An interesting note is that I ran with two buddies this am and we ran a faster pace for about seven miles and I felt fine. Do you think I am just lonely during the week and all the little pains come to my attention?
