Dang my body aches

I could not move this morning. My body was sore/ stiff from doing the 8.6 miles yesterday. So I opt to not even move this a.m.:D. But I knew that I couldn't stay in bed all day. This evening I went to the gym and walked on the treadmill for 30 minutes and did 3 sets 12 of pull up. I can say it help loosing up my body.
