Treadmills were fun for me at one time. However, now that I am have started running outside, joined running clubs, and found trails that I love to run, the treadmill has become almost like a punishment to me. Yesterday, I went to the Y for the first time in some time and ran on a treadmill. To say that I hated it, would be an understatement. I ran for 30 minutes and did not run particularly well . . . Maybe Thanksgiving eating has caught up with me. I did about 3 miles and got a good sweat, but it was a real slog fest over the last 15 minutes, and I felt bored out of my mind. Also, there weren't any inclines or declines to have to adjust for, which is one way that I keep my mind occupied. After the run, my left heel got kind of cranky, which hadn't happened in a long time. However after looking over my blog, I noticed that I said something similar after running on the treadmill one of the last times that I ran on it, so I think this is a sign that I should just avoid the treadmill.
